The BMI USA 6105 is a 3/4 inch lead-free brass union fitting designed for threaded pipe connections in residential and commercial plumbing systems. Built from solid brass, this union provides a reliable, removable connection point that allows sections of pipe to be disconnected without cutting. The lead-free construction meets current potable water standards, making it suitable for use in domestic water supply lines. Plumbers and pipefitters install this fitting wherever a serviceable joint is needed on a threaded run.
This union fitting is appropriate for residential and light commercial plumbing installations, including water supply lines, water heaters, boilers, and similar threaded piping systems. Its 3/4 inch size fits standard NPT-threaded pipe and is a common choice for main branch connections and equipment isolation points.
Designed as an OEM-style replacement or direct-install union fitting for 3/4 inch NPT threaded plumbing systems in residential and commercial applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before beginning work. Apply thread sealant tape or compound to all male threads before assembly. Do not overtighten, as brass fittings can crack under excessive torque.
