Buying Guide: Stainless Steel Pipe Fittings and Valves
Stainless Steel Pipe Fittings
Fittings include nipples, close nipples, caps, couplings, elbows, a tee and a union, with MPT and FPT threads. Match the thread type and size on the old fitting, such as 1/2 in. MPT or 1-1/4 in. FPT, and compare the part number before ordering. The 1/2 in. FPT cap and 1/4 in. MPT close nipple are recommended for use in corrosive environments.
Stainless Steel Ball Valves
Ball valves use a spherical disc to control flow, and flow is allowed when the hole in the disc lines up with the inlet and outlet. The full port valves come in sizes such as 1/4 in. and 3/4 in., with FIP connections, PTFE seats and body seal, and a blow-out proof stem. Confirm the valve size and connection type match the pipe before ordering.
Stainless Steel in Place of Brass
Smith-Cooper's stainless steel fittings and nipples can replace brass, with more corrosion, heat and pressure resistance. They are used in marine, automotive, agricultural, irrigation and plumbing work.
