Hard Plastic Tubing for Drinking Water
Tubing meets NSF/ANSI Standard 61 for drinking water. It is made without plasticizers like DEHP, so it won’t impart tastes or odors to the fluid running through it. A lightweight alternative to copper tubing, it connects to fittings with no heat or soldering required. Tubing is opaque, so you cannot see inside the line.
Polyethylene tubing is compatible with Viega PEX tubing. It connects to barbed fittings with a crimping tool and crimping ring (both sold separately). Tubing is semi-flexible, so it is good for gradual bends. It meets ASTM F876 and ASTM F877 specification and testing requirements for material quality and dimensions of polyethylene (PEX) tubing. It is IAPMO certified to comply with the International Association for Plumbing and Mechanical Officials product performance standards and the Uniform Plumbing Code (UPC) for installation and repair of plumbing systems.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.
