Bmi Usa 35479 Black Malleable Iron Pipe Tee

Product Description

The BMI USA 35479 is a black malleable iron pipe tee designed for threaded pipe systems in plumbing, gas, and mechanical applications. The fitting connects three sections of pipe at a branch point, allowing flow to be split or joined within a run. The reducing configuration accommodates a 1-1/2 inch run, a 1-1/4 inch run, and a 1/2 inch branch outlet, making it well suited for systems where pipe sizing steps down at a junction. Licensed plumbers and pipefitters are the typical installers, though experienced mechanical contractors also work with these fittings in commercial and light industrial settings.

This tee is used in threaded black iron pipe assemblies common to residential and commercial gas distribution, steam systems, compressed air lines, and certain water piping configurations. The black finish indicates an uncoated malleable iron fitting, which is standard for gas piping and steam lines where galvanized coatings are not appropriate. The 1-1/2 x 1-1/4 x 1/2 inch reducing geometry suits applications where a main run transitions to a smaller branch drop or take-off.

Key Features

• Malleable iron construction provides strength and resistance to cracking under mechanical stress
• Black finish suitable for gas piping and steam system installations
• Reducing tee geometry: 1-1/2 inch x 1-1/4 inch run with 1/2 inch branch outlet
• Threaded connections for standard NPT pipe assembly
• Compact and lightweight at 0.98 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems using standard NPT thread connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off gas or fluid supply and relieve system pressure before disassembling any existing piping. Apply an appropriate thread sealant or PTFE tape rated for the intended service before making up threaded connections. Do not over-tighten; use a pipe wrench with a backup wrench on the adjacent fitting to avoid stressing upstream joints.
