B K/mueller Inds(import) 511-931HN Galvanized Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 511-931HN is a galvanized hex bushing used to reduce a 1/2-inch female pipe thread to a 1/4-inch male pipe thread. Hex bushings of this type serve as inline reducers in threaded pipe assemblies, allowing a technician to transition between two pipe sizes without adding a coupling or nipple. The galvanized finish provides corrosion resistance suitable for moderate-exposure environments. This fitting ships in a package of 20 units and is handled and installed by licensed plumbers, pipefitters, and HVAC technicians working on threaded pipe systems.

This hex bushing is appropriate for residential and light commercial threaded pipe installations where a 1/2-inch to 1/4-inch reduction is needed. Common applications include gas line branch fittings, water supply lines, compressed air distribution, and HVAC condensate or refrigerant service ports that use threaded pipe connections. Its compact hex body allows for wrench engagement in tight spaces where a standard reducer coupling would not fit.

Key Features

• Reduces 1/2-inch female pipe thread to 1/4-inch male pipe thread in a single fitting
• Galvanized finish for corrosion resistance in moderate-exposure environments
• Hex body design allows standard wrench engagement during installation
• Packaged in quantities of 20 units, suitable for stocking and service van use

Compatibility

Designed as an OEM-style replacement and general-use threaded hex bushing for 1/2-inch to 1/4-inch NPT pipe reduction applications in plumbing, HVAC, and gas piping systems.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or HVAC technician. Shut off the gas or water supply and depressurize the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for the service medium before threading the bushing into the female fitting. Tighten with a pipe wrench to the fitting manufacturer's standard for the pipe size and material — do not overtighten, as this can crack fittings or damage threads.
