The BMI USA 35070 is a malleable iron pipe coupling finished in black, designed to join pipe sections in industrial and commercial piping systems. This 6 x 4 inch reducing coupling provides a secure mechanical connection between two pipe runs of differing diameters. Malleable iron construction delivers the durability and strength required for demanding trade applications. Licensed plumbers and pipefitters typically install this coupling in gas distribution, water supply, and general mechanical piping where a threaded reducing connection is needed.
This coupling is suited for commercial and industrial piping installations where a 6-inch to 4-inch threaded reduction is required. It is appropriate for use in new construction and retrofit applications across mechanical, plumbing, and gas piping systems. The black finish is standard for gas piping applications in many jurisdictions, making this fitting a common choice for natural gas and propane distribution lines.
Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron piping systems requiring a 6 x 4 inch reducing pipe coupling.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as appropriate. Shut off and depressurize the pipe system completely before removing or installing any coupling. Apply thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not over-tighten or use a pipe wrench in a way that could crack or deform the fitting body.
