    About Pipe and Fittings
    industrial info icon

    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    High-Pressure Iron and Steel Threaded Pipe Fittings

    These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.
    Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

    High-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

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

    High-Pressure Iron and Steel Socket-Connect 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.
