How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.
