The BMI USA 6804 is a 1/2-inch lead-free brass threaded cross fitting designed for use in potable water and plumbing distribution systems. This four-way fitting allows a single supply line to branch in three directions simultaneously, making it a practical choice for residential and light commercial plumbing installations. Constructed from brass, it meets lead-free material requirements applicable to drinking water applications. Licensed plumbers and pipe fitters install this type of fitting during rough-in work and system modifications where a cross-branch configuration is needed.
This cross fitting is suited for residential and light commercial plumbing systems where threaded connections are specified. Its lead-free construction makes it appropriate for potable water lines subject to safe drinking water regulations. The 1/2-inch size fits standard half-inch threaded pipe and is a common size in domestic water supply runs, irrigation headers, and manifold assemblies.
Designed as an OEM-style replacement or new-installation fitting for standard 1/2-inch threaded plumbing systems in residential and light commercial applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before making any connections. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly, and tighten to hand-tight plus a wrench turn — do not overtighten brass fittings, as this can crack the fitting body. Pressure-test the system after installation to confirm leak-free connections.
