About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Push-to-Connect Fittings for Plastic Tubing—High-Purity

For Use With: Air, Nitrogen, Water
Temperature Range: 32° to 100° F
Tubing: Use with polypropylene plastic

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings are produced in a clean room and are double bagged to prevent dirt and moisture from contaminating the inside. They are polypropylene, which has excellent impact and abrasion resistance.
