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.

- Specifications Met: IAPMO Listed, NSF/ANSI 61
Connect drinking water lines with ease—these one-piece fittings have a built-in sleeve that crimps onto tubing for a leak-tight connection that doesn’t require heat or soldering. Each fitting has a viewing hole to prevent installation errors and ensure it’s fully inserted before installing them. Press them onto polyethylene tubing, also known as Viega PEX tubing, using a crimping tool (sold separately). Choose a crimping tool with a grip color that’s the same as your fitting’s ring color. They meet NSF/ANSI 61 for drinking water systems.
Fittings are IAPMO (International Association for Plumbing and Mechanical Officials) certified to comply with product performance standards. They also comply with the UPC (Uniform Plumbing Code) for installation and repair of plumbing systems.
Bronze fittings are strong and resist corrosion.
PPSU Plastic fittings are lighter in weight than copper tube fittings. They also have good corrosion resistance.
