    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.

    FM-Approved Low-Pressure Iron and Steel Flanged-End Pipe Fittings

    Add an access point in fire-protection systems. FM approved, these fittings meet safety standards for reducing the risk of fire. The flat-surface flanged ends mate only to another same-size flat-surface flange, pump, or valve. You’ll also need a gasket (not included). Fittings are made of iron, so they’re best for noncorrosive environments.
