Bmi Usa 35179 Hex Bushing 1-1/2 X 3/8 Inch Black

Product Description

The BMI USA 35179 is a black malleable iron hex bushing used to reduce pipe thread sizes in plumbing, HVAC, and gas piping systems. It features a hexagonal outer profile that accepts a standard wrench for secure installation and removal. The bushing transitions a 1-1/2 inch female NPT connection down to a 3/8 inch male NPT thread. Its black finish is standard for gas line applications. At 0.35 pounds, it is a compact, durable fitting suited for use wherever a threaded pipe size reduction is needed in a professional installation.

This hex bushing is commonly installed in residential and light commercial piping systems where a threaded reduction is required between two pipe segments of different nominal sizes. Typical applications include gas supply lines, steam and hot water piping, compressed air systems, and general plumbing service work. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting as part of routine pipe assembly and system modification work.

Key Features

• 1-1/2 inch female NPT to 3/8 inch male NPT thread reduction
• Malleable iron construction for strength and durability in threaded pipe systems
• Black finish suitable for gas piping applications
• Hexagonal outer body allows wrench engagement for proper torque
• Compact and lightweight at 0.35 pounds

Compatibility

Designed as a standard threaded hex bushing for use in 1-1/2 inch to 3/8 inch NPT pipe reduction applications across residential and commercial plumbing, HVAC, and gas piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable local plumbing and gas codes, including IPC and IFGC guidelines where required. Shut off and depressurize the pipe system completely before disassembling any threaded connections. Apply appropriate thread sealant or tape to the male threads before engagement, and use a wrench on the hex body to tighten to a firm, leak-free connection. Do not overtighten, as malleable iron threads can be damaged by excessive force.
