Legend Valve 416-147 1-1/2 in FNPT Stainless Steel Union 316 Grade 290 psi equipment

1-1/2 in FNPT Stainless Steel Union 316 Grade

This union joins two 1-1/2 inch FNPT threads in industrial plumbing systems. It is made from 316 grade stainless steel for corrosion resistance. The component is rated for 290 psi working pressure. It suits installers who need a removable joint in process piping.

Union design allows quick disassembly without pipe

The three-piece construction lets technicians separate the joint by unthreading the central nut. Female National Pipe Taper threads on both ends accept standard male NPT fittings. 316 stainless steel withstands aggressive fluids and high temperatures. The connection remains tight after repeated make-and-break cycles.

Pressure rating of 290 psi governs system design

Under normal service the union handles the rated pressure without leakage. No moving seals or packing glands are present to wear or generate noise. Installation torque determines joint integrity rather than ongoing power draw. California Proposition 65 warnings apply to chemicals in the product.
