Nibco nfb842xa Press Ball Valve 1 Inch Full Port Lead Free

Product Description

The NIBCO nfb842xa is a lead-free, full-port press ball valve designed for copper press-fit piping systems. Built with a bronze body and brass ball on a bronze stem, this quarter-turn valve delivers reliable shutoff in potable water systems and other plumbing applications. The female press x female press end connections allow tool-based crimping without open flame, speeding up installation and reducing fire risk on the job site. A reinforced PTFE seat seal provides durable, low-friction operation. The NIB-SEAL extended insulated handle gives clear visual indication of valve position and allows operation on insulated lines.

This valve is intended for residential and commercial plumbing systems that require a lead-free shutoff solution compliant with potable water standards. The press-fit end connections make it a strong fit for new construction and retrofit work where torch-free installation is preferred. Licensed plumbers installing copper press systems in water supply lines, mechanical rooms, and similar environments will find this valve straightforward to incorporate into standard press-tool workflows.

Installation Notes

Installation should be performed by a licensed plumber familiar with press-fit copper systems. Shut off and depressurize the supply line and drain the system before installing or servicing this valve. Use only approved pressing tools and correctly sized jaws for 1-inch press connections; an improperly crimped joint will not seal. Verify the unique witness mark is visible after crimping to confirm a completed press joint, and follow all applicable IPC and local plumbing code requirements.
