ATC 5/8 in. Flare X 3/8 in. D CTS Brass Forged Flare Nut

You'll never go back to your old caulk gun again - no job is too big or too small. Even the tightest spaces are no challenge to SILIGUN. The 4 in. patented, lightweight, heavy duty design makes it the most compact, easy to use caulk and silicone gun available and has a powerful thrust ratio of 12:1. Best of all, the fact that you can actually remove excess from the silicone tube, allows you to reach even the tightest spaces, corners, and angles (i.e. behind the toilet). Bottom line, If you can get your hand in there, you can work with the SILIGUN caulking gun. The gun with built-in anti-drip features can be used for all 10 oz. cartridges/sausage packs (310 ml.). Suitable for use with latex, acrylic, silicone caulks and similar compounds. It takes seconds to load and seconds to remove. You are ensured a clean job due to the drip free technology. The SILIGUN also comes equipped with a reusable puncture pin and a hanging hook to keep neatly within reach. When your job is complete, SILIGUN stores away into your toolbox for ready for the next use. Space is never an issue.
