    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.

    Extreme-Pressure Iron and Steel Threaded Pipe Fittings

    The strongest steel fittings we offer, these can withstand extreme-pressure applications.
    Note: The maximum pressure listed for Class 6000 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.
    Straight Adapters with Gasket
    UN/UNF (SAE Straight) Thread—Also known as O-ring boss threads.
    Zinc-Plated Steel—Zinc-plated steel fittings have better corrosion resistance than plain steel fittings.
