About Pipe and Fittings

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

Press-Connect Fittings for Copper Tubing

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
Tubing: Fittings compatible with Viega ProPress or Viega ProPress XL-C: Use with K, M, L copper
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.

Crossover Connectors, Female Press-Connect Tube

Crossover connectors route your line around existing pipe, tubing, or obstructions. By using one crossover instead of multiple elbows, you reduce the number of possible leak points in your line.
