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.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Cleaned and Bagged Solder-Connect
Fittings for Copper Tubing

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

Low-Pressure Socket-Connect Stainless
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

High-Pressure Stainless Steel
Unthreaded Pipe Flanges

Use these heavy duty forged flanges for high-pressure applications.

Bronze Unthreaded Pipe Fittings

Also known as Silbraze fittings.

Brass and Bronze Unthreaded Pipe Flanges

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Brazing Rings for Brass and Bronze
Unthreaded Pipe and Pipe Fittings

Snap one of these rings into an unthreaded pipe fitting and braze to unthreaded pipe for an extra-strong, leak-resistant connection.

High-Pressure Socket-Connect
Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Low-Pressure Steel Unthreaded Pipe Flanges

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

Extreme-Pressure Steel Unthreaded Pipe Flanges

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

Copper-Nickel Unthreaded Pipe

Also known as Pressure Class 200 pipe.

Metal Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Socket-Connect On/Off Valves for Fuel

Install these valves to start and stop the flow of diesel fuel, fuel oil, kerosene, and gasoline. Fire-tested to meet American Petroleum Institute (API) 607, these valves are designed to securely isolate fluid and prevent the spread of fire. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

Gradual On/Off Valves with Solder-Connect Fittings

Solder these valves to copper tubing for a permanent, leak-tight connection.

Gradual On/Off Valves with Press-Connect Fittings

For a leak-tight connection, crimp the press-connect fittings on these valves to metal tubing with a crimping tool—no heat or soldering required. They open and close gradually as the wheel handle turns, preventing sudden starts and stops of flow.
