Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Medium-Pressure Stainless Steel Threaded Pipe Fittings
Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.
Fittings that meet ANSI/MSS SP-114 adhere to high-quality standards for heat treating, material thickness, and marking.
304 stainless steel fittings have very good corrosion resistance.
316 stainless steel fittings have excellent corrosion resistance.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
