    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.

    Medium-Pressure Iron and Steel Threaded Pipe Fittings

    With better strength than our low-pressure iron and steel pipe fittings, these can handle medium-pressure applications. They are for use in noncorrosive environments.

    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.
