    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Low-Pressure Galvanized Iron and Steel Threaded Pipe Flanges

    The galvanized finish on these flanges provides fair corrosion resistance. Also known as Pressure Class 150 flanges, they are for use in low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.
