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.
Unions separate into three pieces for easy access to your line. Union adapters for galvanized steel threaded pipe join copper tubing to galvanized threaded connections on hot water heaters.
