    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 Flanges

    Also known as Pressure Class 1500 flanges, these have the strength to handle high pressures. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are for use in noncorrosive environments.
