Barbed Tube Fittings for Drinking Water
- Temperature Range: 32° to 180° F
- Tubing: Use with hard polyethylene plastic
- 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. Fittings are compatible with Viega PEX fittings. Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.
Brass fittings offer good corrosion resistance.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
