The BMI USA 35441 is a malleable iron black tee fitting used to create branch connections in threaded pipe systems. The tee connects a 1-inch run on both ends to a 1/4-inch branch outlet, allowing a smaller line to tap off a main pipe. Weighing 0.55 pounds, this fitting is well-suited for low-pressure gas, air, and compatible fluid distribution lines in residential and light commercial plumbing and mechanical systems. Licensed plumbers and pipefitters are the primary installers. The black finish is standard for gas service applications and meets typical code requirements for that use.
This tee is commonly used in residential and light commercial installations where a 1-inch threaded main line requires a 1/4-inch branch takeoff. Typical applications include gas piping systems, compressed air distribution, and steam or water lines where malleable iron fittings are specified. The reducing configuration makes it practical for instrumentation taps, gauge connections, or secondary branch feeds without requiring an additional reducing coupling.
Designed as an OEM-style replacement or standard-service fitting for threaded malleable iron pipe systems using NPT connections in residential and light commercial gas, air, or fluid piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas service, or IPC requirements for plumbing applications. Shut off and depressurize the line completely before disassembling or installing any fitting. Apply an approved thread sealant or PTFE tape to all male NPT threads before assembly. Do not overtighten malleable iron fittings, as the material can crack under excessive torque.
