Bmi Usa 35453 Black Malleable Iron Pipe Tee 1-1/4x1-1/4x1

Product Description

The BMI USA 35453 is a black malleable iron pipe tee used to create branch connections in threaded piping systems. This fitting joins three pipe runs at a single point, allowing flow to be directed or split across a system. Weighing 1.06 pounds, it is built from malleable iron for reliable strength under pressure and temperature cycling. The black finish is standard for gas piping applications and meets typical code requirements for that service. Licensed plumbers and pipefitters install this type of fitting in both residential and light commercial systems.

This tee is sized at 1-1/4 inches by 1-1/4 inches by 1 inch, with the branch outlet reduced to 1 inch. It is a standard reducing tee configuration used where a smaller branch line taps off a main run. Common applications include natural gas distribution lines, propane supply piping, and black iron steam or water systems where malleable iron fittings are specified. The threaded ends accept standard NPT pipe threads for straightforward field assembly.

Key Features

• Malleable iron construction provides durability and resistance to mechanical stress and vibration
• Black finish suitable for natural gas and propane piping applications
• Reducing outlet configuration: 1-1/4 inches run by 1 inch branch
• NPT-threaded ends for standard field assembly with pipe wrenches
• Weighs 1.06 pounds — solid and consistent with OEM-grade fittings

Compatibility

Designed as a standard NPT malleable iron reducing tee for use in threaded black iron piping systems where 1-1/4 inch run and 1 inch branch connections are required.

Installation Notes

Installation of black iron pipe fittings is typically performed by a licensed plumber or pipefitter. Shut off and verify the absence of gas or fluid pressure before breaking any connection in the line. Apply an approved pipe thread sealant or PTFE tape rated for the intended service to all threaded joints. Gas piping work must comply with applicable local codes and IFGC requirements; pressure-test the completed assembly before returning the system to service.
