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.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Straight connectors fully threaded from one end are also known as merchant couplings. They are threaded all the way in one direction.

Threaded female x butt weld straight adapters are also known as half couplings.

Female x male 90° elbow adapters are also known as street elbows.

High-Pressure Galvanized Steel Threaded Pipe Fittings

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Class 3000 fittings, they have excellent strength to handle high-pressure applications.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Threaded female x butt weld straight adapters are also known as half couplings.

Female x male 90° elbow adapters are also known as street elbows.

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 pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.

Union straight connectors separate into three pieces for access to your line.

Socket connect x butt weld straight adapters are also known as half couplings.
