Bmi Usa 35278 Black Malleable Iron 45 Degree Street Elbow

Product Description

The BMI USA 35278 is a 1-1/2 inch black malleable iron 45 degree street elbow designed for threaded pipe systems in plumbing, mechanical, and industrial piping applications. A street elbow features one male-threaded end and one female-threaded end, allowing direct connection to a fitting without a short nipple. The black finish is achieved through an oil-dip or lacquer coating, making this fitting suitable for gas distribution, steam, and non-corrosive fluid systems where galvanized coatings are not required. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This 45 degree street elbow is used in residential and light commercial piping systems where a directional change is needed in tight spaces. The street configuration eliminates the need for an extra nipple between fittings, saving space and reducing potential leak points. Typical applications include natural gas supply lines, steam piping, compressed air systems, and general water distribution where black iron fittings are specified. The 1-1/2 inch size suits branch and main line connections in moderate-flow applications.

Key Features

• Malleable iron construction for strength and resistance to mechanical stress
• Black finish suitable for gas, steam, and non-potable fluid systems
• 1-1/2 inch pipe size fits standard NPT threaded connections

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the supply line before removing or installing any threaded fittings. Apply pipe thread sealant or PTFE tape to male threads before assembly and tighten to manufacturer-specified engagement using a pipe wrench. Do not overtighten malleable iron fittings, as cracking or thread damage may result.
