IN-Fittings are leak-free push-to-connect fittings with a gripping mechanism that utilizes different components to hold tubing in place and create a pneumatic seal. Stainless steel retaining ring grabs onto the tubing with teeth to ensure a strong hold. The Oring, which is available in either BUNA-N or viton, rests below the retaining ring and seals on the tubing. Sizes from 1/8 to 1/2 in, with threads from 10-32 to 1/2 in. NPT.
