Bmi Usa 35475 Malleable Iron Black Pipe Tee

Product Description

The BMI USA 35475 is a malleable iron black pipe tee designed for joining threaded pipe runs in plumbing, gas, and mechanical piping systems. This reducing tee connects a 1.5-inch run on both ends with a 1.25-inch branch outlet, allowing directional splits or branch connections in a single fitting. Malleable iron construction provides the strength and ductility required for threaded iron pipe systems operating under pressure. Licensed plumbers and pipefitters are the primary installers in both residential and light commercial applications.

This black pipe tee is suited for use in gas distribution, compressed air lines, water supply, and hydronic heating systems where malleable iron fittings are specified. The black finish distinguishes it from galvanized fittings and is standard for gas service piping in many jurisdictions. Its reducing configuration handles branch flow at a smaller diameter than the main run, making it a common choice when stepping down to a 1.25-inch branch line off a 1.5-inch main.

Key Features

• Malleable iron construction for strength and resistance to cracking under stress
• Black finish suitable for gas service and general iron pipe systems
• Reducing tee configuration: 1.5 x 1.25 x 1.5 inches for branch line step-down
• Threaded ends compatible with standard NPT threaded iron pipe
• Weighs 1.45 pounds, indicating substantial wall thickness for pressure-rated use

Compatibility

Designed as an OEM-style replacement and standard fitting for threaded malleable iron pipe systems using NPT connections in residential and light commercial installations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code or International Fuel Gas Code where gas service is involved. Shut off the gas or water supply and depressurize the line before threading or unthreading any fittings. Apply an approved thread sealant or PTFE tape rated for the service medium before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack if forced beyond hand-tight plus the recommended turns with a pipe wrench.
