Bmi Usa 6438 Lead Free Brass Threaded Tee 1x1x3/4

Product Description

The BMI USA 6438 is a lead free brass threaded tee fitting designed for use in potable water and plumbing distribution systems. This three-outlet fitting allows a branch connection off a main run, redirecting or splitting flow in a piped system. The 6438 features a 1 inch by 1 inch by 3/4 inch configuration, with the reduced outlet accommodating a common step-down to a branch line. Constructed from solid brass, it is suitable for threaded pipe assemblies in residential and light commercial installations. Licensed plumbers and pipefitters are the primary installers of this fitting type.

This fitting is used in water supply piping where a tee connection is needed to branch off a main line. The 1 inch run ports suit standard main supply lines, while the 3/4 inch branch port connects to a reduced lateral line. Typical applications include domestic water distribution, irrigation manifold connections, and general plumbing rough-in work. The lead free construction meets requirements for potable water contact in residential and commercial plumbing systems.

Installation Notes

Installation of threaded brass fittings should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off the water supply and relieve system pressure before threading any fitting into service. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as excessive force can crack brass fittings or distort thread engagement.
