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 Tube Fittings for Drinking Water

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.
