Bmi Usa 20108 1-1/2 Inch Black Malleable Iron Pipe Union

Product Description

The BMI USA 20108 is a 1-1/2 inch extra heavy (XH) malleable iron pipe union finished in black, rated at 300 PSI. Pipe unions allow for the disconnection and reconnection of pipe runs without cutting, making them essential for service access and future maintenance. This fitting is constructed from extra heavy malleable iron for durability in demanding piping systems. Licensed plumbers and pipefitters install this type of fitting in steam, gas, and water distribution systems where a secure, removable joint is required at a fixed point in the line.

This union is suited for commercial and industrial piping applications where extra heavy fittings are specified. The 300 PSI pressure rating and XH construction make it appropriate for higher-pressure service conditions beyond standard black iron fittings. It is commonly installed in mechanical rooms, boiler piping, steam distribution headers, and industrial process lines where black iron fittings are the standard of practice.

Key Features

• Extra heavy (XH) malleable iron construction for high-pressure service
• 300 PSI pressure rating suitable for steam, gas, and water piping
• 1-1/2 inch size for standard pipe connections
• Black finish compatible with standard black iron piping systems
• Union design allows pipe disconnection without cutting for future serviceability

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch black iron piping systems requiring extra heavy union connections at 300 PSI rated service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the piping system fully before removing or installing any union fitting. Apply appropriate thread sealant or thread tape to all threaded connections before assembly. Do not over-tighten the union nut, as malleable iron threads can be damaged by excessive force.
