    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.

    Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings with Sealant

    The male threads on these fittings have a sealant applied for extra leak protection. Fittings are made of galvanized iron or steel, which have fair corrosion resistance. Also known as Pressure Class 125 or 150 fittings, they are for use in low-pressure applications.

    Precision Extreme-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

    Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings. They are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces. They are galvanized steel, which has fair corrosion resistance.
