Nibco nf932xc 1-1/2 in Press Spring Check Valve Lead Free

Product Description

The NIBCO nf932xc is a lead-free bronze in-line spring check valve designed for press-fit piping systems in residential and light commercial plumbing applications. It uses press x press female end connections with an inboard bead and EPDM O-rings, allowing a licensed plumber to complete a permanent, watertight joint in seconds using a standard press-fit tool — no flame, solder, or flux required. The valve is rated to 250 psi non-shock cold working pressure and holds a maximum temperature rating of 300 degrees F at 100 psi. The spring-actuated, lift-type internals use resilient discs to provide reliable backflow prevention with minimal pressure drop.

This valve is suited for potable water distribution lines where lead-free compliance and press-fit joinery are required. It is commonly installed in domestic water systems serving residential construction, multi-family buildings, and light commercial facilities. The press connection style eliminates open-flame soldering, making it well suited for tight mechanical spaces or fire-sensitive environments. At 1-1/2 inches, it fits standard copper tube sizes used in main distribution and branch supply runs.

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-1/2 inch press-fit copper piping systems in lead-free compliant domestic water applications.

Installation Notes

Installation is performed by a licensed plumber using a compatible press-fit tool sized for 1-1/2 inch connections. Shut off the water supply and depressurize the line before inserting the valve. Verify tube ends are clean, deburred, and fully seated against the valve stop before pressing. Observe all applicable local plumbing codes and IAPMO or IPC requirements governing check valve installation and flow direction.
