Bmi Usa 35029 Black Malleable Iron Pipe Coupling

Product Description

The BMI USA 35029 is a black malleable iron pipe coupling designed to join two sections of threaded pipe in mechanical, plumbing, and gas piping systems. Finished in black, this coupling provides a clean, corrosion-resistant connection suitable for low-pressure applications in both residential and light commercial settings. Machined from malleable iron for strength and durability, the 35029 accepts a 1-inch by 3/8-inch threaded configuration, making it a reliable transition or joining fitting for mixed-diameter pipe runs. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting as part of standard threaded-pipe assemblies.

This coupling is suited for use in gas distribution, water supply, compressed air, and general mechanical piping systems where threaded black iron fittings are specified. It is commonly installed in residential gas lines, boiler rooms, commercial kitchens, and industrial service drops where a transition between pipe diameters is required. Its black finish makes it appropriate for natural gas and propane piping applications where black iron pipe is code-specified.

Key Features

• Malleable iron construction provides strength and resistance to mechanical stress in threaded assemblies
• Black finish suitable for gas and general mechanical piping applications
• 1-inch by 3/8-inch configuration supports diameter transitions in threaded pipe runs
• Standard threaded ends for compatibility with NPT-threaded pipe and fittings
• Lightweight at 0.3 pounds for easy handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement or standard service fitting for threaded black iron pipe systems using NPT connections in plumbing, gas, and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local codes, including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off all gas or water supply and depressurize the line before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all threaded joints before assembly. Do not over-tighten threaded connections, as this can crack malleable iron fittings and compromise the seal.
