Bmi Usa 35131 Black Malleable Iron Hex Bushing

Product Description

The BMI USA 35131 is a black malleable iron hex bushing used to reduce a larger threaded pipe opening to a smaller threaded fitting. The hex profile provides a flat wrench surface for reliable torque during installation without slipping or rounding. This bushing transitions a 1-inch female thread down to a 1/8-inch male thread, making it a standard pipe fitting for reducing connections in gas, air, and general piping systems. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during new construction and retrofit service work. It weighs 0.21 pounds and carries a black iron finish suited for ferrous piping systems.

This hex bushing is commonly used in residential and light commercial applications where a pipe thread reduction is needed at valves, manifolds, gauges, or branch connections. The 1-inch by 1/8-inch size is frequently encountered when adapting standard pipe runs down to instrument ports or small-diameter control line connections. Its malleable iron construction allows for reliable thread engagement under moderate stress and vibration typical of mechanical system environments.

Key Features

• Hex profile provides flat wrench surface for secure installation without pipe wrench slippage
• Malleable iron construction resists cracking under thread stress and moderate vibration
• Black iron finish compatible with standard ferrous pipe system conventions
• 1-inch female NPT to 1/8-inch male NPT reduction in a single compact fitting
• Lightweight at 0.21 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement or standard service fitting for threaded pipe systems requiring a 1-inch to 1/8-inch reduction in malleable iron construction.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded ferrous piping systems. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape to male threads per applicable IPC or IFGC requirements for the system type. Do not over-torque malleable iron fittings, as cracking can occur under excessive force.
