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: 35° to 150° F
Tubing: See table
Specifications Met: NSF/ANSI 61

Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. Also known as instant fittings, they 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. All meet NSF/ANSI 61 for use in drinking water systems.

Solder-Connect Fittings for Copper Tubing

Temperature Range: 32° to 200° F

Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61, EN 1057, or DVGW GW 8(P).

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
