The BMI USA 6131 is a lead-free brass hex bushing designed for threaded pipe connections in plumbing and mechanical systems. This fitting reduces from a 1-1/4-inch female thread to a 1-inch male thread, allowing technicians to transition between pipe sizes within a threaded assembly. The hex body provides a flat wrench surface for secure, torque-controlled makeup without marring the fitting. At 0.42 pounds, it is a compact, solid-brass component suited for potable water, commercial plumbing, and general fluid service applications where lead-free compliance is required.
This hex bushing is used in residential and light commercial plumbing installations where pipe diameter reductions are needed within a threaded system. Typical applications include water supply lines, distribution manifolds, and mechanical room piping. The lead-free brass construction meets requirements for contact with potable water systems. Licensed plumbers and pipefitters install this fitting during rough-in and trim-out phases of construction and repair work.
Designed as an OEM-style replacement hex bushing for standard NPT threaded pipe systems requiring a 1-1/4-inch to 1-inch reduction in residential and commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not overtighten brass fittings, as the material can crack under excessive force.
