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 180° F
Tubing: Use with hard polyethylene plastic
Specifications Met: ASTM F1807, NSF/ANSI 61

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). They have multiple barbs that grip onto tubing. Fittings are compatible with Viega PEX fittings. Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61. They are brass for good corrosion resistance.
