Bmi Usa 35321 Black 90 Degree Street Elbow 1/2x1/8

Product Description

The BMI USA 35321 is a malleable iron black 90-degree street elbow designed for threaded pipe systems in plumbing, gas, and general industrial piping applications. The fitting connects a 1/2-inch male thread on one end to a 1/8-inch female thread on the other, allowing a sharp directional change in tight or restricted runs. The black finish indicates this fitting is uncoated malleable iron, suited for gas lines and non-corrosive fluid systems. Licensed plumbers and pipefitters install this type of fitting where a standard elbow and nipple combination would consume too much space. The compact one-piece design simplifies assembly and reduces potential leak points in the joint.

This street elbow is used in residential and light commercial piping systems where threaded iron pipe is the standard connection method. Typical applications include natural gas distribution lines, compressed air runs, and low-pressure steam or water systems. The 1/2-inch to 1/8-inch reduction makes it useful where a line transitions from a larger distribution pipe down to a smaller branch outlet or instrument connection. The fitting is appropriate for indoor applications where thread-seal compound or PTFE tape is applied per local code requirements.

Key Features

• 90-degree street elbow configuration with male and female threaded ends on the same fitting
• 1/2-inch male NPT to 1/8-inch female NPT reducing configuration
• Malleable iron construction provides strength and impact resistance in threaded pipe assemblies
• Black finish suitable for natural gas and non-potable water piping systems
• Compact one-piece design reduces assembly steps compared to a standard elbow plus nipple

Compatibility

Designed as an OEM-style replacement or standard service fitting for threaded malleable iron pipe systems using NPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable local plumbing and mechanical codes. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly and tighten to a proper engagement without over-torquing, which can crack the fitting. Gas line installations must be leak-tested after assembly in accordance with local gas codes and IFGC guidelines.
