The BMI USA 6274 is a lead-free brass street 45-degree elbow fitting in a half-inch male-by-female (MXF) configuration. Designed for threaded pipe installations, this fitting allows a 45-degree directional change in a run without requiring an additional nipple, since the male thread is machined directly into the fitting body. The lead-free brass construction meets current potable-water standards, making it suitable for use in domestic water supply lines. Licensed plumbers and pipefitters install this type of fitting in both new construction and retrofit applications where a compact, low-profile elbow is needed.
This street 45-degree elbow is used in residential and light commercial plumbing systems where a half-inch threaded line requires an angled transition. Typical install scenarios include water supply branch lines, fixture connections, and close-quarter runs where space does not allow a standard elbow plus nipple combination. The MXF thread pattern connects directly to a female-threaded fitting, valve, or port on one end and accepts a female-threaded connection on the other.
Designed as an OEM-style replacement or new-installation street elbow for half-inch NPT threaded plumbing systems in residential and light commercial applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply line before removing any existing fitting or making new connections. Apply thread sealant tape or pipe compound to the male threads before assembly, and tighten to snug with a pipe wrench — do not overtighten brass threads, as this can crack the fitting body. Inspect for leaks after restoring pressure.
