X 12 Resealable Silicone Sealant Caulk Mastic Cartridge Nozzle Caps

Everyone knows the problem once a silicone cartridge has been opened it has a very short life 

We have all done it and put a screw into the end but this does not work

Are you fed up with throwing out hardened part used tubes?

Then these are for you!

They will pay for themselves in a very short time.

The caps provided with some brands
are nice but they do not work because the
air is still getting in.

These screw caps hold an
O-Ring to seal the cartridge 100% airtight.

Made From a Hard Wearing Plastic.
NO CARTRIDGE OR SEALANT APPLICATOR INCLUDED.
