Bmi Usa 35477 Malleable Iron Black Pipe Tee

Product Description

The BMI USA 35477 is a malleable iron black pipe tee designed for joining threaded pipe runs in plumbing, gas distribution, and mechanical piping systems. This reducing tee connects a 1-1/2 inch run pipe to a 1-1/4 inch run outlet and a 1 inch branch outlet, making it a practical fitting for systems that require a step-down in pipe size at the branch point. The black finish is standard for gas service applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting in both residential and light commercial work.

This tee is suited for low-pressure gas lines, steam systems, and water distribution piping where malleable iron fittings are specified. The reducing configuration handles three different pipe sizes in a single fitting, reducing the need for additional bushings or couplings at the branch. Typical installations include residential gas supply lines, boiler rooms, and mechanical rooms where schedule 40 black iron pipe is standard.

Key Features

• Reducing tee configuration: 1-1/2 inch x 1-1/4 inch x 1 inch threaded connections
• Malleable iron construction for strength and thread integrity under pressure
• Black finish suitable for gas service and steam piping applications
• Threaded ends accept standard NPT pipe threads
• Compact form factor at 1.22 pounds for easier handling during installation

Compatibility

Designed as an OEM-style replacement or standard-service fitting compatible with schedule 40 black iron pipe in 1-1/2 inch, 1-1/4 inch, and 1 inch NPT-threaded configurations.

Installation Notes

Installation of malleable iron threaded fittings is typically performed by a licensed plumber or pipefitter. Always depressurize and isolate the pipe section before disassembly or fitting installation. Apply an approved pipe thread sealant or PTFE tape rated for the service type, whether gas or water, before threading the fitting onto the pipe. Follow applicable codes including IFGC for gas piping and IPC for water and drain systems.
