Bmi 35445 Malleable Iron Black Tee 1x3/4x1/2

Product Description

The BMI 35445 is a reducing malleable iron tee finished in black, designed for threaded pipe systems in plumbing and mechanical applications. This fitting connects three pipe runs at a branch point, accommodating a 1-inch run with a 3/4-inch through-port and a 1/2-inch branch outlet. Malleable iron construction provides the ductility and strength needed to handle mechanical stress, vibration, and thermal cycling in working piping systems. Licensed plumbers and pipefitters install this type of fitting in gas distribution, water supply, and industrial piping where reliable threaded connections are required.

This tee is suited for residential and light commercial plumbing and mechanical piping systems. The reducing configuration handles transitions between pipe sizes in the same assembly, eliminating the need for separate reducers at the branch. Typical applications include gas supply lines, water distribution headers, and black iron piping systems where NPT-threaded fittings are specified. The black finish is standard for gas piping installations per common trade practice.

Key Features

• Malleable iron construction for ductility and resistance to mechanical stress
• Black finish standard for gas and industrial piping applications
• Reducing tee configuration: 1 inch x 3/4 inch x 1/2 inch eliminates need for separate reducers
• NPT-threaded connections for compatibility with standard threaded pipe systems
• Three-way branch fitting for splitting or combining flow in a piping run

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded black iron pipe systems used in plumbing, gas distribution, and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code, or the International Fuel Gas Code where gas service is involved. Shut off the gas or water supply and depressurize the line before disassembling any existing fittings. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections; use a pipe wrench with a backup wrench to avoid stressing adjacent fittings or pipe.
