The BMI USA 35584 is a malleable iron pipe tee designed for use in threaded pipe systems where a branch connection is required. This fitting measures 3 inches by 3 inches by 1 inch and features a black finish applied over the malleable iron construction. Malleable iron provides strong resistance to mechanical stress and is well suited for gas, air, and compatible fluid distribution lines. Weighing 4.04 pounds, it is a solid, full-bodied fitting intended for commercial and industrial piping installations. Licensed plumbers and pipefitters are the primary installers of this type of threaded fitting.
This tee fitting is used in threaded black iron pipe assemblies common to commercial gas distribution, compressed air systems, and general piping infrastructure. The 3 x 3 x 1 inch configuration allows a full-size run with a reduced branch outlet, making it useful where a smaller branch line must be tapped off a main run. It is appropriate for both above-ground indoor installations and accessible mechanical room applications where black iron pipe is the specified material.
Designed as an OEM-style replacement or direct-use fitting for standard NPT threaded black iron pipe systems in residential, commercial, and light industrial piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off and depressurize the pipe system fully before cutting into any existing line. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before threading the fitting. Do not over-tighten threaded fittings, as malleable iron threads can crack under excessive force.
