About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

For Use With: Drinking Water
Maximum Pressure: Fittings compatible with Viega ProPress or Viega ProPress XL-C: 200 psi @ 72° F
Fittings compatible with Viega Pex or Viega PureFlow Press: 100 psi @ 72° F
Temperature Range: 0° to 250° F

Fittings compatible with Viega Pex or Viega PureFlow Press: Use with hard polyethylene plastic
Specifications Met: See table

Crimp these fittings to copper tubing with a crimping tool (sold separately). An O-ring on the inside of the fitting creates a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings. Fittings have good corrosion resistance. They meet NSF/ANSI safety standards for use with drinking water systems.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
