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.

Brass Push-to-Connect Fittings for Copper Tubing
- Tubing: Use with K, M, L copper, polyethylene plastic, CPVC
Connect these fittings to copper tubing with a push—no heat, solder, or flux required. They have an internal gripping ring and O-ring that hold the fitting secure. They also come with a tube support or retainer if you want to use them with polyethylene plastic (PEX) tubing. They are also known as instant fittings. Fittings are brass for good corrosion resistance. They are compatible with SharkBite® fittings. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61.

A release clip is required to disconnect the fitting from the tubing.
Use release clips with a depth gauge to mark how far you need to insert your PVC pipe into its fitting to ensure a watertight connection.
