Questions about Little Red Cap Contractor Pack Caulk Saving Cap, Red (Pack of 35) (LRC.50) (Original Version)
Q:
It would seem like, for longer periods, it would still work best to put a nail in the tip before putting this on...any thoughts?
Answer: The nail will temporarily work for you, but air will still get in and harden the caulk. The Red caps provide a secure seal and are easy to remove and reuse.
Answer: I am an electrician, I use clear silicone occasionally. I was always throwing away partially used tubes. These babies really work all by themselves, no need for a nail, or a wire nut or duct tape. I've used the same tube for months now, just a dab every couple of weeks. I'm sold on them. I've actually given more away than I have used myself because they are reusable
Answer: nails tend to build up rust as a chemical reaction from caulk thats why i bought these sometimes you can reuse them if you are careful taking them on and off i usually use them once or twice my only request would be that they come in larger pkg maybe 500 in a pack so far these are the best for caulking tubes
Answer: I don't think a nail would make a better seal and it just may introduce air that might make it worse. The trick is to make a good seal and keep all of the air out. I wipe off the spout and squeeze out about half a drop of fresh caulk and then roll on the red cap. I have had some tubes of Dap 230 and Alex plus that I sealed with the red caps over a year ago that were ready to go after rolling the red cap off.
Answer: That would work the best.
Answer: If you're sealing latex caulk, the nail may rust and discolor the caulk. The jury is still out with me and this product.
Answer: As tight as these fit, I'd prefer the cap to the nail.
Q:
how are they packaged in this offer from Amazon? Other listings show a plastic box.
Answer: The one that I purchased came in a little round plastic box, 35 count. I also must say, THEY WORK GREAT!
Answer: They are packaged in a little round plastic container - very convenient and easy to stow.
Answer: They come in a small round plastic container. It's a little larger than a tin of shoe polish. They're well worth the money. I've saved tubes of Simpson strong tie epoxy, liquid nails, silicone and poly caulk for weeks and months with these.
Answer: A small round plastic box for convenient storage.
Q:
Are these meant for ~10 oz. cartridges only? Or will they also fit on "quart"-sized (29 oz.) cartridges?
Answer: They will also fit the 29 oz cartridges as well.
Answer: They are a one size fits all product. I use them on the big cartridges.
Answer: I have never used them on the larger tube but I believe they will work just fine.
Answer: Yes. They will fit on any size cartridge. The only thing that matters is the size of the nozzle. Note that if you cut a very large opening in a nozzle (3/8ths or larger) the caps can be a little harder to put on - otherwise they work well on just about anything.
Answer: They will fit the quart size
Answer: Probably, they stretch out. If it will fit in a caulk gun then I would say yes ?
Answer: I've used them on both,there is plenty of stretch,and with a little care they are good for many tubes over time
Answer: Although I have not tried the larger tubes, these caps seem to have enough stretch to seal them properly.
Answer: I have only used it on 10 oz, and they have worked well. Putting it on a 29 oz might be stretching to far for an air tight seal.
Answer: They're stretchable and fit on both. They don't work for me though. The DAP Caps do work well, especially if you squirt some goop into the cap before shoving the nozzle in, so as to make a broad sealing surface between the nozzle and the cap.
Answer: They fit on most of the cartages I have used, as well as glue bottles. In my opinion they are great. But I feel they are somewhat expensive for what you get.
Answer: They will fit on both. Check the price now, they have gone down in price. They can be used over and over again.
Answer: I am not sure. But I assume that they would.
Q:
Does it work for silicone RTV (which is very hard to seal unless the tube has a snap on cap)?
Answer: Yes, if it is in a caulking type tube. It wouldn't work if you buy it in the smaller metal squeeze tubes.
Answer: Yes. I've sealed RTV for over a month using these caps.
Q:
Are these meant for ~10 oz. cartridges only? Or will they also fit on "quart"-sized (29 oz.) cartridges?
Answer: They will also fit the 29 oz cartridges as well.

Answer: I have never used them on the larger tube but I believe they will work just fine.
Answer: Yes. They will fit on any size cartridge. The only thing that matters is the size of the nozzle. Note that if you cut a very large opening in a nozzle (3/8ths or larger) the caps can be a little harder to put on - otherwise they work well on just about anything.

Q:

Q:
How much does the item weigh? It says 10 pounds, is this correct???
Answer: That must be a misprint. The container is similar in size to a round breath mint container. I would think much closer to 10 ounces rather than pounds.
Answer: 10# is wrong. it weight almost nothing. just a small rubber sleeve which rolls over the open end of the caulk tube.
Answer: Amazon site says .07 pounds so it is very light. All 35 caps in the plastic container weight less than one AA battery.
Answer: No. It's a small, round plastic container that holds the red caps. A few ounces, at most. Unless you buy them by the dozens, it's not a 10-lb shipment.
Answer: It doesn't even weigh 10oz.
Answer: Less than 1/4 of a pound
Answer: Same answer as 1972mgb. Container a few ounces at most.
Q:
Can these little caps be reused? Or is each cap a one-time use kind of thing?
Answer: Yes they can, pretty sturdy so they can be reused until they crack or get a hole, which doesn't happen easily. Like a rubber band, they will crack with time though.
Answer: Frirst off these things are great. I own and operate a remodeling company. We use these on every tube of caulk that we don't finish. They can be reused until you finish the tube. We keep a pack in every van. Worth every penny!
Answer: yes they are reusable however products like Liquid Nails does dry and make it hard to pull the "red cap" off to reuse.. but that's after the tube sits for over a few weeks!
Answer: Yes, they unroll on the tube and roll back up to take them off. Reuse will be limited by time, rather than number of uses, as they deteriorate over time, crack and fall apart. Still a great way to seal a tube, just not for long time storage.
Answer: I use multiple times. Key is to make sure the tip is basically clean before placing on for best long term use
Answer: I am re-using them as they seem sturdy enough and should be able to get multiple uses out of each one with minimal care.
Answer: Yes. It's best if you wipe off the tube nozzle first.
Product reviews of Little Red Cap Contractor Pack Caulk Saving Cap, Red (Pack of 35) (LRC.50) (Original Version)
John Schaben : Good buy
These things are pretty neat. Do the job very nicely and at about 35 cents apiece wont take long to pay for themselves given all the partial tubes of adhesives, caulks and sealants I've had to trash over the years. The idea isn't new by any means but the application is unique. My Dad told me that they used to cover the rifle muzzles in WWII with condoms to keep dirt and mud from jamming the weapon and this is a very similar issue, keeping air from contaminating the tube contents.
John Duke : Never throw a dried up calking tube again
This will save you money and well worth the price for the amount you get. No more dried calking in the tube when you start to use it. Just roll it on the calking tube and when ready to use again just roll it off the calking tube. The rubber forms a air tight fit around the applicator
The Editor : Little wonders
I hope the inventor got a patent and reaps the rewards. The picture looks like a fat doughnut. In reality, the Little Red Cap is a tiny but thick caulk-tube condom. Roll down the sides to seal a caulk tube or glue bottle. For longer term storage, the instructions suggest, leave a little room at the tip and squeeze out a few drops of caulk or adhesive. It'll cure into a plug. Also, they say, consider using two Little Red Caps at a time. Thanks to these little wonders, I can stop in the middle of a tube and take whatever time I need before coming back to the job. One cap can reseal a tube -- or a wood-glue bottle -- several times.
Gary C : Works great
I waited a while to write this review to see if they really worked. After using these on several tubes of caulking and storing it for a number of weeks, I had to re-use some. Once the cap was removed the caulk came out without any problem. It had not dried at all near the tip. This is far better than using a 16d nail and duct tape.
MargaretNC : DIYers need this too, because they caulk less often
The Little Red Cap is a clever and effective solution that is useful for DIYers too, because they use smaller amounts of caulk much less frequently than professional contractors. As others have mentioned, the tip of your caulking tube will spear through this cap if you apply it too tightly, and the hole may not show up for a few days. Leave a little space at the end so the the cap lasts longer.
Thomasj106 : Simple but ingenious idea.
These caps are really a very good idea. They beat "the screw in the end of the nozzle" trick any day. Even the snap on caps that come with some caulks don't seal out air as well as these do. Caulks last so much longer when the air can't get to them. I have been using these since I first saw them on the market maybe 7-8 years ago. Buying them here was easy and they were shipped to me fast.
xcalibur12 : Just made my second order....
Very often, simple is better. These caps are extremely simple to use and they do the trick. Try not to pull them down too tight, if you have cut a sharp point on your caulk tube, as you can puncture them. Other than that, they are simple and quite effective. I highly recommend.
DWD : Fantasic
Excellent simple invention that will save your tube for a very long time. Have spent plenty of time trying to re-use a tube of construction glue or caulking months later just to discover it hardened. Not now! This works really good.
John Duke : Never throw a dried up calking tube again
This will save you money and well worth the price for the amount you get. No more dried calking in the tube when you start to use it. Just roll it on the calking tube and when ready to use again just roll it off the calking tube. The rubber forms a air tight fit around the applicator
El Dorado Dave : Great idea!
What a great idea! Lots of different applications for these, but the caulking tips definitely work well. I put a couple on the tips of my epoxy bottles too. They roll on, well, like a condom. Unlike a condom, they can be removed and reinstalled. Probably pay for themselves in eliminating one or two tubes of wasted caulk or glue.
Saliandra : The best condom for your caulk! Seriously, these work great!
These little covers are so great! I have had them on several tubes of caulk, some of which I placed over a year ago. The caulk is still soft and pliable and easy to work with. Yep - with these little red condoms, you want your caulk to remain soft, haha!
AY : ABSOLUTELY AMAZING = keeps silicone tube fresh for a year -- with intermittent use !
I have tried everything over 35 years to keep from wasting half used tubes. I bought these in 2017 -- and have used them on caulk. silicone, roofing cement, etc. When the red cap "condom" is removed, there is 3/4 inch of solid - then the good stuff. I sometimes use small screwdriver to remove the plug.
$$$$$$ ===HINT FOR USE ===$$$ -- After at least 25 applications, I have learned to start it on the erasure end of a pencil -- the proper side for application isn't obvious. By starting the "condom" on a pencil you will determine the proper application -- and I leave a little of the end unraveled -- it's easier to apply to a tube with a large end.
This stuff is the "real deal" -- I bought 4 - in case they become unavailable in the future. AMAZING.

Rev357 : I've uncapped one of these a month later and been able to get a good flow of caulk without having to mess around
Where have these been all my life!? I've used painters tape for years in order to try to get more than one use out of a caulk cartridge, with mixed success. These little caulk condoms have been very helpful. Spread your caulk, slip one on, push a bit more caulk into the tip to get a seal, and then put it away. I've uncapped one of these a month later and been able to get a good flow of caulk without having to mess around.
Mr. Green Thumb : For Caulk
This is good for GE silicone but don't expect it to work for adhesive.
I used it on Loctite 3x polyurethane adhesive and it got stuck on overnight.
When I removed it, it tore a hole in the tip and the product still cured.
Since then I just let the product ooze out and seal itself.

kindle reader : Highly recommend!!
I didn't even know anything like this existed until it popped up on my screen while I was shopping for something else. Ordered them because I had just ordered industrial adhesive and had no way to seal it after I used it. These are amazing, I haven't used the adhesive yet be cause of all the rain we have had, but I tried one on a small bottle of glue that was always drying in the cap and clogging the nozzle. It works great. No more drying glue and no more clogging. I love it!!!
48-fordf-1 : Good to cap those open leaky cartridges
They seem to work good so far
Kenn AH : What a great idea !
I have used these a couple of times on tubes of calk.
It's only been about 2 weeks but so far so good.
The quality is there ( meaning these can be used over & over) & the calk is kept fresh.
Will it keep an open tube of calk fresh for several months ?
Only time will tell but I am pleased thus far
4/23/12, I have had one open tube of calk covered with one of these " Little Red caps " for over 4 weeks .
I took the red cap off today & checked the first bit of calk out of the tube , no signs of tried out calk
meaning no waste. The cap is constructed of quality material & I was able to reuse the cap again. Very Pleased

J. McGaw : Simple, but they worked perfectly
Who would have thought that a condom for a caulking tube was a practical idea? Well, they really do work amazingly well. I just got done re-using a tube of construction adhesive opened in the Spring of 2014 that was sealed with one of these and it was still in perfect condition. Sadly, I bought a pack of 35 back then and managed to lose it somewhere among construction detritus after only using a few. So, here in 2018, I bought a new package (the smaller one this time) so that they would be on hand. Now to find someplace to put them where they won't get lost...
BU Engineering Grad : Great glue saver
I do a bit of woodworking. Seems like every time I start a project, I have to clean the glue tip from what dried up last time. These has caused me to nearly destroy a few glue bottle tips. I was considering buying one of those specialty glue bottle until I found these. They work great and some the problem. No need to transfer glue to a special bottle which would probably had the same issue.

G. Farnsworth : Perfect for caulk and for protecting your shirt from your pens!
I really love these and recommend them to everyone. I have two uses for them:
1. The main use I have for them is the one for which they are designed: keeping tubes of caulk good between uses. In the past I used to put a plastic bag over the end and then wrap a rubber band around. The problem with that (besides looking terrible) is that these caulk tubes have very low friction at the end and frequently the plastic and rubber band would come off quite easily. These caps do a much better job. I don't really like actually exposing the rubber to the caulk or adhesive or whatever. So what I do is put a small square (maybe 2x2 inches) of plastic or saran wrap over the tip, then put this on top--if you want to store for a very long time and are worried about it drying, you can insert a nail in the end before putting on the plastic. This product unwraps just like a condom. It exerts pressure all along the end of the caulk tube and goes past the plastic square...it stays on and looks good. When you want to take them off, you just unroll from the bottom and they come off and look just like they did before use. So you can use them over and over (if you put plastic on there first. At Ace there are plastic caps that are intended to do the same thing but they don't work nearly as well. Actually there are several competing products but this is by far the best.
2. I also put this on the ends of my clicky pens that I wear in my shirt pocket. They are gel pens similar to a pilot G2. The problem with that type of pen is that if it ever gets clicked open inadvertently, it will soak into your shirt and ruin it. Put this over the end and that will never happen. You can carry your pens without adding bulk to your pocket and without worrying about ruining your shirts. Basically this is a much improved pocket protector.
Anyway, this is a great product. These two uses are really quite important to me, so I will always keep them around.

Roger : These are great! If you want your caulk to last two ...
These are great! If you want your caulk to last two or three times longer add some aluminum foil to the tip before applying this cap. Aluminum is a much better moisture barrier
Rich : can't say enough good things about this extremely cleaver solution to a life ...
can't say enough good things about this extremely cleaver solution to a life long issue of sealing caulking tubes and glue bottles -- also seems to work well protecting my pencils in my toolbox -- have recovered 2 phillips screwdrivers that have been used to seal tubes for the past 40 years -- reusable probably forever
Davey Jones : GREAT Invention
These are the cleverest product! After using nails, tape, screws, and caps for years, this product keeps the caulk "fresh" in an opened tube the best. Also, you don't end up with rust discoloration when you start. I think that they work exceptionally the first time used - but may not be quite as good upon re-use because of introduced caulk, dirt, etc.
Walter : a must get
when your using a lot of silicone and calking tubes, these little rubbers will safe the unused portion of you silicone for months.
T H. : simple and reasonably effective
A nice quick way to seal an open caulk tube for later re-use. Probably would not last forever, but neither does an unopened tube.
Jimbone : A great product and at an unbeatable price.
I read about this product in the Family Handyman. It's simple and yet innovative. Makes you wonder. Damn why didn't I think of this. As a DIY, I've tried lots of things to seal a half used caulk tube. Screws, plastic and rubber bands, plumber's putty. The plumber's putty actually got me about 90% success in reusing these caulk tubes. But now with these Little Red Cap I'm never going back. Bluntly put they work like a condom. Sealing out all air and moisture. Reusing can be tricky as sometimes they lose their elasticity or shape and can be challenging putting them back onto the caulk tube's end. I guess pretty much like a real condom which you shouldn't reuse, right?
donald d. : GREAT
These little condoms are the the best .Always had a problem with sealing a tube of calk-NO MORE
Kim : Who'd have thought a caulk-tube-condom would generate such pleasure!
I come from the school of, "shove a 10 penny nail into the open end of a partially used tube of caulk and hope the next time you yanked it out with a pair of pliers it would be usable!" But, those days are gone. Now I roll one of those little red condoms over the tip of the tube and voila, an air-tight seal that lasts and lasts. (I had one tube that was so old the condom had lost its elasticity, but the caulk still emerged...too old to be usable, but still soft). I reuse the Red Caps util they somehow disappear on their own or get too crusty to roll/unroll. I love these little red guys!

Pink Taco Bandit : I’m on the fence, but leaning towards good
14 Jul 2019: They’re basically mini condoms for your opened tubes. The rubber thickness is about the thickness of your average blow up balloon.
I got these for cheap so I did buy a few packs. Unsure on how long your tubes will remain fresh, but I do like that I don’t have to widen the hole with a screw.
I’m on the fence because they do rip easy (basic ballon thickness). Only time will truly tell if they’re worth it or if I should go back to using a screw, cling wrap and a rubber band.

Mark's Amazon : Awesome Caulk Caps, almost perfect
Awesome little caulk tube condoms! They work great but using a nail and then covering it with the red cap condom is the best solution I have found!
My only problem with these is that polyurethane type construction adhesives eat through the red caps and then dries out. My solution for construction adhesives is to use a nail and use two caulk caps. They are longer than necessary and a sharp caulk tube tip can puncture them during storage.
Please make caps to resist poly chemicals.

The Editor : Little wonders
I hope the inventor got a patent and reaps the rewards. The picture looks like a fat doughnut. In reality, the Little Red Cap is a tiny but thick caulk-tube condom. Roll down the sides to seal a caulk tube or glue bottle. For longer term storage, the instructions suggest, leave a little room at the tip and squeeze out a few drops of caulk or adhesive. It'll cure into a plug. Also, they say, consider using two Little Red Caps at a time. Thanks to these little wonders, I can stop in the middle of a tube and take whatever time I need before coming back to the job. One cap can reseal a tube -- or a wood-glue bottle -- several times.
G. Farnsworth : Perfect for caulk and for protecting your shirt from your pens!
I really love these and recommend them to everyone. I have two uses for them:
1. The main use I have for them is the one for which they are designed: keeping tubes of caulk good between uses. In the past I used to put a plastic bag over the end and then wrap a rubber band around. The problem with that (besides looking terrible) is that these caulk tubes have very low friction at the end and frequently the plastic and rubber band would come off quite easily. These caps do a much better job. I don't really like actually exposing the rubber to the caulk or adhesive or whatever. So what I do is put a small square (maybe 2x2 inches) of plastic or saran wrap over the tip, then put this on top--if you want to store for a very long time and are worried about it drying, you can insert a nail in the end before putting on the plastic. This product unwraps just like a condom. It exerts pressure all along the end of the caulk tube and goes past the plastic square...it stays on and looks good. When you want to take them off, you just unroll from the bottom and they come off and look just like they did before use. So you can use them over and over (if you put plastic on there first. At Ace there are plastic caps that are intended to do the same thing but they don't work nearly as well. Actually there are several competing products but this is by far the best.
2. I also put this on the ends of my clicky pens that I wear in my shirt pocket. They are gel pens similar to a pilot G2. The problem with that type of pen is that if it ever gets clicked open inadvertently, it will soak into your shirt and ruin it. Put this over the end and that will never happen. You can carry your pens without adding bulk to your pocket and without worrying about ruining your shirts. Basically this is a much improved pocket protector.
Anyway, this is a great product. These two uses are really quite important to me, so I will always keep them around.

Hculbert : Great as a cap for air tools
I did buy this on a friend's recommendation as a cap for keeping dirt out of air tools. It will, however, also serve me well in keeping partial tubes of caulk and adhesive! They are doing the job for the air tools. I'll have to see in a month or two when I go to use a partial tube of caulk. I'll also be interested to see how long the rubber remains good on the air tools.
S. Albert : Review Still In-Progress - So Far NOT Impressed
I used this "caulk condom" on a tube of GE Silicone II. It didn't work as expected. The tube wrapper was applied as you would expect, but it must not have been air-tight. There was a bit of a bubble at the tip. When I tried to use the silicone after 2 months, the silicone in the rigid tube was cured. I busted out caulk from the back when I pushed too hard.
Previously, I've used liquid Plasti-Dip on my caulk tubes and it has worked amazing- the filling has been as fresh as when I first snipped the tip. The only bad thing about Plasti Dipping your tubes is that it tends to run, so you need to dip it a few times until you build up a layer of the liquid on the tip, and then find some way to let it hang straight down while it dries.
I tried this caulk saver again this past weekend on a tube of Polyseamseal Tub & Tile Ultra. This had previously been Plasti-Dipped and it performed like a champ. We'll see if the tube sock works as well. I'll update this review if the produc improves with time.

Florida Bourne : Indispensable
Great product for your caulking tube and will keep your male cat from impregnating the the neighborhood
Tal A. : Cheaper than any other solution out there
This things are great!
I won't say they're sealing 100% but they seal good enough. My tubes last much longer now than just wrapping the tips with a masking tape.
You'll still need to run in a rod to clean any clogs but it's noticibly fresher. As long as you don't puncture them and when removing rolling all the way to original shape, they would last for more than one tube.

CoconutGrover : Finally - Something that works
I got these after reading a magazine article. I had my doubts because the tape solution never works. Well i used this on acrylic caulk. A month or two later i took it off and to my surprise there was absolutely no hardened caulk. I can not speak for other caulks/adhesives, but for the acrylic it worked great. And they are very easy to apply and remove.
UPDATE- Used on Polyurethane sealant and sealant was hardened in the nozzle after 3 months; i took 1 star off.
Still way more convenient than tape and i believe it works better. I plan to continue using them.
UPDATE 6/2020- Generally pleased with them, especially for relatively short term use. Reordering and back to 5 stars...

E. Sikorski : Saves money on caulk - worth the price after using only a few!
This has helped me save many tubes of caulk. It is so much better than the plastic red cap/tooling device I bought at HD. The caulk stays flexible and easy to restart. Just pushing the metal rod on your caulk gun through the end a few times is enough to get it going again. In fact, most tubes usually start right up without even having to do that. I have had tubes sit in the basement for well over 6 months and still work fine. These are reusable as well...as long as you don't get too much wet caulk on them. Definitely a must for everyone's tool bench/box.
DRMORRIS1 : Single Use
Don’t plan on using these more than once. They shred when you remove them.
Oakley24 : Multiple uses, and these just work
After trying a million ways to save caulk, adhesives, glue, etc, I have finally found the solution. There is nothing more frustrating than having to buy more caulk, even though you have 3/4 of a tube that was used only 3 months before.
These little rubber caps work really well. I have not had them break as others have, they seem to be thick enough to handle the angled tip that I usually cut on caulk tubes. And after 6 weeks, I took this cap off and my caulk was as fresh as the day I opened it. Hopefully, it will stay that way for longer, but I haven't had the chance to test longevity yet.
I also use them for my air tools, since most of the plastic caps that came with them are broken or have disappeared. Also on my glue bottles, even though they close pretty tightly, I think this keeps air out completely. And I keep looking for more ways to take advantage of this ingenious product.

Jeff Geerling : Elegant solution to an annoying problem!
I've tried many different things to preserve the tips of my caulk tubes from hardening, leaking, or completely clogging (thus wasting a tube of caulk or glue!). These little caps are deceptively simple, but work very well. I've used them on a few tubes now, and they work better than duct tape or cellophane.
I've tested these with Alex Plus, Liquid Nails, and standard white latex caulk, and the next time I've used the caulk, it came out easily. Just make sure you clean the tip of the caulk tube after you're finished using it, and put on the little red cap fully.

Sleepy Joe Biden : These Work Pretty Well - But There is A Better Way
The Little red Caps are a great idea. They are easy to use, but putting them on without breaking them takes a little practice. They preserve the unused caulk for quite awhile. I keep they on hand because they are quick and easy. My only complaint is the cost. They seem expensive for a small container of rubber.
There is a very low cost alternative that preserves the opened caulk for the life of the original product. Seal the open end of the caulk tube with hot glue. The hot glue seals completely and is easily removed when it comes time to use it again. This takes a little longer than the red caps but it is less expensive and more effective.

Mutt : Keeps my tubes for a month or more.
Easier and cleaner than nails or screws, and better than tape. Everyone I show them to has bought a pack.
