50 Pcs Glue Mouth Protective Cover Caulk Sealer Saver Silicone Nozzles Accessories Red Caulk Saving Cap for Sealing and Preserving

good bye to throwing away half used tubes, works really well.. buy buy buy

A really good price against the potential of what you can gain. Very pleased.Easy to use to cap your partially used silicone mastic tubes. Just clean them off after use and you can reuse them again, No more throwing part used tubes away when I've only used the a bit.

So handy. Why has no one ever thought if this before...

Didn't believe for one minute that these would work, but fed up of digging out nozzles full of solid silicon and caulk so thought I would give them a try. Absolutely wonderful, they preserve the contents superbly and it is available to use whenever.They protect your tubes like the adult versions protect ******!Buy them, you won't regret it.

I put them on the tubes and only one ripped and I think that was my fault as the tip was really sharp but for by that if you use a lot of silicone these are a must excellent invention

Does the job very well.

I use adhesive and caulk almost every day, though these would be a good idea. Unfortunately every one I have used seems to work but when I go get it the next day I find that they have burst and the caulk has dried out. Better just buying new cartridges.

Nice tight seal so hopefully will enable me to keep sealant for longer.
