Bmi Usa 35021 Black Malleable Iron Pipe Coupling

Product Description

The BMI USA 35021 is a black malleable iron pipe coupling designed for joining threaded pipe sections in plumbing, gas, and light industrial piping systems. Machined from malleable iron with a black finish, this coupling provides reliable mechanical strength at threaded connections where a reduction from 1/2 inch to 1/8 inch pipe size is required. The black finish indicates an uncoated, oil-dipped surface treatment standard for gas and air line fittings. Licensed plumbers and pipefitters install this fitting as part of low-pressure distribution runs in residential and light commercial applications.

This coupling is suited for residential and light commercial piping installations where a 1/2 inch to 1/8 inch threaded reduction is needed. Typical applications include natural gas supply lines, compressed air distribution, and general-purpose pipe assemblies where malleable iron fittings are specified. The black finish is the standard choice for gas service, distinguishing it from galvanized fittings used in water service.

Key Features

• Malleable iron construction provides strength and resistance to cracking under mechanical stress
• Black oil-dipped finish standard for gas and air line service
• 1/2 inch to 1/8 inch reducing configuration for pipe size transitions
• Threaded connection compatible with standard NPT pipe threads
• Lightweight at 0.15 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or standard stock fitting for threaded malleable iron pipe systems requiring a 1/2 inch to 1/8 inch reducing coupling.

Installation Notes

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 applicable. Shut off and depressurize the pipe system completely before removing or installing any fitting. Apply an appropriate thread sealant or tape rated for the service medium before threading the coupling onto the pipe. Do not overtighten threaded connections, as malleable iron fittings can crack if excessive force is applied.
