    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 Iron and Steel Unthreaded Pipe Flanges

    Forged for extra strength, these heavy duty flanges can withstand high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line.

    Low-Pressure Iron and Steel Threaded Pipe Fittings with Sealant

    To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection. Also known as Pressure Class 125 or 150 fittings. Made of either iron or steel, they’re best in noncorrosive environments. Even with sealant, threaded connections can be taken apart for maintenance and repair.
