Solder-Connect Fittings for Copper Tubing
- Temperature Range: 32° to 200° F
Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
- For Use With: Drinking Water
- Tubing: Use with K, M, L copper
- Specifications Met: See table

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.
Straight adapters with flanged end bolt to equipment or other flanged connections found on pumps and valves to create a convenient access point.

High-Temperature Steam-Resistant Metallic Pipe Gaskets
Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil. The metal construction provides structural strength. These gaskets can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards.
Corrugated gaskets conform to rough and uneven surfaces when put under low pressure for a tight seal.
Smooth gaskets can withstand higher pressure than the corrugated gaskets.
