- Thick, flexible vinyl
- Keeps moisture and solvents in and air out
- Caps grip snuggly to nozzle
- Stores on caulking gun hanger while caulking, for hands free control
- Help prevent open caulking tube from drying out
This is the on...
This is the only cap I have ever found that actually works. Others are hard plastic and they either fit or don't and allow air into the caulking tube. This one is
soft and pliable and stretches enough to fit but stays tight enough to seal. I won't use anything else.
