Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Barbed Tube Fittings for Drinking Water
- Temperature Range: 32° to 180° F
- Tubing:
All Fittings: Use with hard polyethylene plastic
Socket-Connect Fittings: Use with hard polyethylene plastic or copper - Specifications Met: See table
Connect these fittings to tubing with a ring and a crimping tool (both sold separately). They have multiple barbs that grip onto tubing for a secure hold. Fittings are compatible with Viega PEX tubing. Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.
Brass, bronze, and copper fittings have good corrosion resistance. PPSU Plastic fittings offer corrosion resistance at a lighter weight.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
