Mueller Industries 113-526 Brass Gas Ball Valve 1-1/4 in Fip

Product Description

The MUELLER INDUSTRIES 113-526 is a one-piece forged brass gas ball valve designed for shutoff and flow control on gas distribution lines. The one-piece body construction reduces leak paths and extends service life compared to multi-piece assemblies. It features a 1-1/4 inches female iron pipe (FIP) inlet and a 1-1/4 inches FIP outlet, making it a direct threaded connection on both ends. The square head handle is yellow, a standard visual indicator that identifies the valve as part of a gas service line and allows for quick open/closed identification. Licensed plumbers and gas fitters install this valve in residential and light commercial piping systems.

This valve is rated for use with natural gas, LP gas, oils, and general plumbing service. It is suited for residential gas supply lines, appliance isolation, and light commercial gas distribution where a full-port, threaded shutoff is required. The forged brass body provides corrosion resistance in typical indoor and buried-adjacent installations. The 1-1/4 inches FIP x 1-1/4 inches FIP end configuration fits standard iron pipe and compatible fittings commonly found in residential and commercial gas rough-in work.

Installation Notes

Installation must be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the upstream gas supply and verify zero pressure before removing or installing any valve. Apply an approved thread sealant or PTFE tape rated for gas service to all male threads before making up connections. After installation, perform a leak test with an approved gas leak detection solution before restoring service.
