How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Brass and Bronze Unthreaded Pipe Flanges

Bolt these flanges to equipment or to another same-size, flat-surface flange with a gasket (sold separately). They have good corrosion resistance.

Socket-connect flanges braze onto unthreaded pipe with a brazing ring (sold separately) for a strong, leak-resistant connection. They are also known as Silbraze flanges.

Bronze Unthreaded Pipe Fittings

Snap a brazing ring (sold separately) into these fittings and braze them to unthreaded pipe for a strong, leak-resistant connection. Fittings are also known as Silbraze fittings. They are bronze, which is compatible with brass and has good corrosion resistance.

Union connectors separate into three pieces so you can access your line.

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.

Press-Connect Fittings for Copper Tubing

For Use With: Drinking Water
Maximum Pressure: 200psi @ 72° F
Temperature Range: 0° to 250° F
Tubing: Use with K, M, L copper
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.

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

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