The BMI USA 6412 is a lead-free brass threaded tee fitting designed for use in potable water, plumbing distribution, and general piping systems where a 4-inch branch connection is required. Constructed from solid brass, this tee provides a durable, corrosion-resistant junction point for splitting or combining flow in a threaded piping run. Its lead-free construction meets the requirements for use in drinking water applications. Licensed plumbers and pipefitters install this type of fitting in both residential and light commercial plumbing systems where code compliance and material integrity are essential.
This tee fitting is suited for threaded pipe installations in water supply and distribution systems, mechanical rooms, and plumbing retrofits. The 4-inch size makes it appropriate for main line branch connections in larger residential builds or commercial plumbing applications. It is installed by licensed plumbers and pipefitters working with NPT-threaded pipe systems.
Designed as an OEM-style threaded brass tee for use with standard 4-inch NPT-threaded pipe in potable water and general plumbing distribution systems.
Installation should be performed by a licensed plumber in accordance with the applicable edition of the International Plumbing Code. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to all male threads prior to assembly. Do not overtighten threaded connections, as brass fittings can crack under excessive torque.
