The BMI USA 35316 is a malleable iron black 90-degree reducing elbow designed for threaded pipe installations. This fitting connects a 3/8-inch pipe to a 1/4-inch pipe at a right angle, allowing directional changes in low-pressure gas, air, or fluid distribution systems. The black finish indicates a standard non-galvanized iron coating suitable for gas line and industrial piping applications. At 0.13 pounds, this compact fitting is lightweight without sacrificing the strength and durability malleable iron construction provides. Licensed plumbers and pipefitters install this type of elbow where a run changes direction and a pipe size reduction is needed in the same connection point.
This reducing elbow is suited for residential and light commercial piping systems where threaded malleable iron fittings are specified. Typical applications include natural gas distribution, compressed air lines, and general-purpose fluid piping. The 90-degree angle makes it appropriate for tight-space routing where a straight coupling and separate elbow would not fit. Plumbers and gas fitters working on black iron pipe systems will find this a standard component for branch takeoffs and directional changes that also require a step-down in pipe diameter.
Designed as an OEM-style replacement or standard-service fitting for threaded black iron pipe systems using NPT connections in residential and light commercial gas and fluid piping applications.
Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off the gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service type before threading the fitting. Hand-tighten first, then wrench-tighten to a snug fit without over-torquing, which can crack malleable iron fittings.
