Nibco 39923347374 Lead Free Ball Valve 1/2 in Fnpt 600 Psi

Product Description

The NIBCO 39923347374 is a two-piece, full-port brass ball valve in the T-FP-600A-LF series, rated at 600 psi cold working pressure and engineered for lead-free drinking water service. The valve features a brass body, brass ball, brass stem, and PTFE ball seats, with a 0.56-inch orifice and FNPT end connections on both inlet and outlet. A standard lever handle provides quarter-turn shutoff operation. This valve meets NSF/ANSI 61-8 and NSF/ANSI 372 lead-free requirements and complies with California AB1953 and Vermont Act 193 (111-380) for potable water service. Licensed plumbers and mechanical contractors install this valve on residential and light commercial piping systems.

The T-FP-600A-LF series is designed for hot and cold water distribution and gas applications where a lead-free, full-port shutoff is required. The full-port bore minimizes pressure drop across the valve, making it well suited for domestic water lines, hydronic systems, and fuel gas piping where flow restriction must be kept to a minimum. The FNPT connections allow direct threaded installation into standard pipe fittings without adapters.

Compatibility

Rated for hot and cold water and gas applications. Designed as a lead-free, full-port threaded ball valve replacement suitable for 1/2-inch FNPT piping installations in systems requiring NSF/ANSI 61-8 and 372 certification.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IFGC requirements for gas service. Shut off the water or gas supply and relieve system pressure completely before removing the existing valve or threading the new valve into place. Use appropriate thread sealant or PTFE tape rated for the service medium on all FNPT connections. Do not exceed the 600 psi cold working pressure rating, and verify that the lever handle has adequate clearance for full quarter-turn operation after installation.
