The BMI USA 6378 is a lead-free brass street 90-degree elbow designed for threaded pipe systems. This male-by-female (street) configuration allows the fitting to thread directly into another fitting without a nipple, simplifying assembly in tight spaces. Constructed from solid brass, it is suited for potable water, plumbing distribution, and hydronic applications where lead-free compliance is required. At 1.15 pounds, the fitting is sized for 1-1/2 inch pipe connections. Licensed plumbers and pipefitters are the primary installers for this type of fitting.
This street elbow is used in residential and light commercial plumbing systems where a 90-degree directional change is needed in a threaded piping run. The male-by-female street design eliminates the need for an additional coupling or nipple at one end, making it a practical choice for retrofit work, service calls, and new rough-in applications involving 1-1/2 inch threaded pipe.
Designed as an OEM-style replacement and standard fitting for 1-1/2 inch NPT threaded piping systems in residential and light commercial plumbing installations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before disassembling any threaded connections. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten, as this can crack fittings or damage threads.
