Connection Geometry & 316 Stainless Steel Construction

This BSPP female y-piece three-way branch fitting features one-piece investment cast three-way y-pattern body in a three-port y-branch (y-piece) profile, providing BSPP Parallel Female (Three Ports) connections for modular stainless steel piping, equipment hookups, and manifold assemblies. Manufactured in 316 (CF8M) Stainless Steel, the fitting offers molybdenum-bearing austenitic corrosion resistance suited for process water, chemical transfer, utility air, and washdown environments.

Size Coverage & Thread Assembly

Dimensioned generally in accordance with ISO 4144 (150 LB series) as stated on the series datasheet (a reference dimensional design rather than full standard certification). The series covers nominal sizes across 1/8"–2". 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 BSPP female y-piece three-way branch fitting, verify that your mating ports match the BSPP Parallel Female (Three Ports) interface and select an appropriate thread sealant or gasket for the joint. Specify the required nominal size from 1/8"–2" and confirm installation clearance when ordering.
