Value Collection B-BUS0705 Black Iron Bushing 3/4x1/2 Class 150

Product Description

The VALUE COLLECTION B-BUS0705 is a black-finish malleable iron pipe bushing rated for Class 150 service. It reduces a 3/4-inch female threaded port down to a 1/2-inch male threaded connection, making it a standard component in threaded pipe assemblies across plumbing, gas, and HVAC piping systems. With a 300 psi liquid and gas pressure rating, this bushing handles typical low-pressure piping loads without issue. The black finish is standard for gas-line applications. Both connections are NPT-threaded for compatibility with standard trade pipe fittings.

This bushing is used wherever a threaded reduction is needed between 3/4-inch and 1/2-inch pipe. Common install scenarios include gas supply drops, black iron HVAC piping manifolds, compressed air lines, and general plumbing rough-in work. Plumbers, pipefitters, and HVAC technicians reach for this type of fitting when transitioning between pipe sizes on threaded iron systems in both residential and light commercial applications.

Key Features

• Malleable iron construction handles vibration and mechanical stress better than cast iron
• Black finish suited for gas-line service per common field practice
• Class 150 rating with 300 psi pressure capacity for liquid and gas service
• Threaded end connections on both male and female sides for tool-only assembly
• Reduces 3/4-inch to 1/2-inch — one of the most common pipe reduction sizes in the trade

Compatibility

Designed as an OEM-style replacement or standard-stock fitting for threaded black iron pipe systems using 3/4-inch and 1/2-inch NPT connections in Class 150 piping assemblies.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians in accordance with IFGC, IPC, or locally adopted codes depending on service type. Shut off gas or fluid supply and depressurize the line before installation. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before making up the threads. Do not use a pipe wrench on the fitting body in a way that could crack or distort the threads.
