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
Create an access point in extreme-pressure lines. Also known as Pressure Class 1500 flanges, bolt two of the same size together with a gasket (not included). These flanges are made of iron or steel, so they're best for noncorrosive environments.
