Bmi 35455 Malleable Iron Tee Black 1-1/4x1/2

Product Description

The BMI 35455 is a black malleable iron tee fitting designed for joining and branching pipe runs in plumbing and piping systems. The main run measures 1-1/4 inches with a 1/2 inch branch outlet, making it suitable for reducing branch configurations in supply and distribution lines. Malleable iron construction provides the strength and ductility needed to handle mechanical stress in threaded piping assemblies. This fitting is installed by licensed plumbers and pipefitters working on commercial and residential black iron pipe systems, including gas distribution, compressed air, and general plumbing applications.

The BMI 35455 is used in black iron threaded pipe systems where a reducing tee is needed to branch off a smaller line from a larger main. Typical applications include natural gas distribution piping, compressed air lines, fire sprinkler systems, and industrial plumbing where black iron pipe is specified. The reduced branch connection allows integration of a 1/2 inch line into a 1-1/4 inch main run without additional reducers in many configurations.

Key Features

• Malleable iron construction for strength and resistance to mechanical stress in threaded assemblies
• Black finish suited for gas, air, and non-potable water piping applications
• 1-1/4 inches main run with 1/2 inch reducing branch outlet
• Threaded connections compatible with standard NPT black iron pipe
• Tee configuration supports straight-through flow with a side branch takeoff

Compatibility

Designed as an OEM-style replacement and standard fitting for black iron threaded pipe systems using NPT connections in plumbing, gas, and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fitting. Apply appropriate thread sealant or tape rated for the intended service to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
