Product overview
Connection Geometry & 316 Stainless Steel Construction
This BSPT close taper male nipple in 316 stainless steel pipe is machined from 316 seamless pipe with close back-to-back taper threads in a compact close-coupled double-male pipe nipple profile, providing BSPT Taper Male × BSPT Taper Male (R, ISO 7-1) connections for modular stainless steel piping, equipment hookups, and manifold assemblies. Manufactured in 316 Stainless Steel Pipe (ASTM A312), the fitting offers molybdenum-bearing austenitic corrosion resistance suited for process water, chemical transfer, utility air, and washdown environments.
Size Coverage & Thread Assembly
The series covers nominal sizes across 1/8" to 4" (12 nominal pipe sizes). Refer to the dimensional schedule on this product page to match each thread size against its corresponding envelope length, outside diameter or across-flats width, and unit weight. Before installing this BSPT close taper male nipple in 316 stainless steel pipe, verify that your mating ports match the BSPT Taper Male × BSPT Taper Male (R, ISO 7-1) interface and select an appropriate thread sealant or gasket for the joint. Specify the required nominal size from 1/8" to 4" (12 nominal pipe sizes) and confirm installation clearance when ordering.
