The BMI USA 35052 is a 3x2 inch black malleable iron pipe coupling used to join sections of threaded pipe in plumbing, mechanical, and piping systems. Machined from malleable iron and finished in black, this reducing coupling steps down a 3 inch connection to a 2 inch connection in a single fitting. It is suited for gas, water, and general plumbing piping where a durable threaded reducing connection is required. Licensed plumbers and pipefitters are the typical installers in both residential and commercial applications.
This coupling is used in black iron gas piping systems, industrial fluid systems, and general plumbing where threaded pipe assemblies require a size reduction. The black finish is standard for gas distribution piping and is compatible with schedule 40 threaded pipe assemblies. It is commonly installed in mechanical rooms, utility spaces, and gas distribution runs where a 3 inch to 2 inch reduction is needed.
Designed as an OEM-style replacement or direct-use fitting for threaded black iron pipe systems requiring a 3 inch to 2 inch reducing coupling.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code where relevant. Shut off gas or water supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not overtighten threaded fittings, as malleable iron threads can crack under excessive torque.
