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.

Temperature Range: 32° to 200° F
Tubing: Use with K, M, L copper, polyethylene plastic

Connect these fittings to copper tubing with a push—no heat, solder, or flux required. They have an internal gripping ring and O-ring that hold the fitting secure. They also come with a tube support if you want to use them with polyethylene plastic (PEX) tubing. They are also known as instant fittings. Fittings are brass for good corrosion resistance. They are compatible with SharkBite® fittings. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61.
