Nibco 39923349231 Lead Free Ball Valve 3/4 in Threaded

Product Description

The NIBCO 39923349231 is a 3/4-inch, two-piece, full-port lead-free ball valve from the T-585-66-LF series, designed for water supply systems where potable water safety compliance is required. The silicon bronze body pairs with a stainless steel ball and stem, rated to 600 psi CWP and 300 degrees F. RTFE seats provide low-friction shutoff with consistent seal integrity. The NIB-SEAL extended insulated handle allows secure actuation and reduces heat transfer to the operator. Licensed plumbers and pipefitters install this valve in both residential and commercial water distribution lines as a durable, code-compliant shutoff.

This valve is intended for applications that deliver water for human consumption, including residential and commercial construction. It meets NSF/ANSI 61-8 (rated to 180 degrees F for potable water contact) and NSF/ANSI 372 for lead-free compliance. The full-port, 3/4-inch orifice maintains maximum flow with minimal pressure drop. The threaded end connections are suited for typical iron-pipe-thread installations in supply lines, distribution manifolds, and branch shutoffs.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IAPMO or IPC standards. Shut off the water supply and depressurize the line fully before removing the existing valve or making any threaded connections. Apply thread sealant or tape rated for potable water service to all male threads before assembly. Do not exceed the rated pressure or temperature limits during system commissioning or pressure testing.
