The BMI USA 6271 is a lead-free brass street 45-degree elbow fitting sized at 1/8 inch, configured in a male-by-female (MXF) thread arrangement. It allows directional changes in threaded piping runs without the need for a separate coupling, making it a compact solution for tight-quarter installations. Constructed from lead-free brass, this fitting meets current potable-water material standards. Plumbers and pipefitters install this type of fitting in low-pressure threaded systems where a 45-degree offset is needed along a run.
This street elbow is suited for residential and light commercial plumbing applications where 1/8-inch threaded connections are used. The MXF configuration means one end threads directly into a female-threaded fitting or valve, while the female end accepts a male-threaded pipe or fitting. Typical uses include water supply lines, instrumentation connections, and compressed-air service lines operating within the fitting's rated pressure range. Its small size makes it a common stocking item for service vans and shop inventory.
Designed as an OEM-style replacement or standard stock fitting for 1/8-inch threaded brass piping systems in plumbing and light mechanical 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 relieve system pressure before removing or installing any threaded fitting. Apply thread sealant tape or paste to the male threads before assembly and tighten with a pipe wrench to achieve a leak-free connection without over-torquing. Inspect the joint for leaks after restoring system pressure.
