Nibco njb83txb Lead-free Bronze Ball Valve 1-1/4 in

Product Description

The NIBCO njb83txb is a two-piece, lead-free bronze ball valve designed for 1-1/4 inch nominal pipe size with female solder cup end connections. The valve body is constructed from lead-free bronze, with a silicon bronze stem and ball, meeting requirements for potable water service. A quarter-turn operation — 90 degrees from fully open to fully closed — gives technicians fast, reliable shutoff. The two-piece body design simplifies field service and internal inspection without removing the valve from the line. This valve is suited for residential and commercial plumbing systems where lead-free materials are required by code.

The njb83txb is intended for potable water supply applications in both residential and light commercial construction, including domestic water distribution systems. The female solder cup ends allow connection to copper tubing using standard soft or hard solder methods. The lead-free bronze construction satisfies requirements under NSF 61 and NSF 372 standards for drinking water component materials, making it appropriate for new construction and renovation projects subject to lead-free mandates.

Compatibility

The njb83txb is listed under NIBCO model S-585-80-LF-NS, Series S-585-80-LF. It is designed as an OEM-style replacement or new-installation valve for 1-1/4 inch copper tubing systems requiring lead-free bronze construction.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the system before soldering. Allow the valve body to cool fully before operating the valve after soldering, as excessive heat during the connection process can damage internal seals. Refer to the NIBCO technical data sheet and valve selection guide for pressure and temperature ratings before installation.
