B K/mueller Inds(import) 511-942HN Galvanized Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 511-942HN is a galvanized hex bushing used to reduce a 3/4-inch female threaded connection down to a 3/8-inch male threaded connection. This fitting is designed for threaded pipe assemblies in plumbing, HVAC, and gas-distribution systems where a reduction between NPT fittings is required. The galvanized steel construction provides corrosion resistance suited to water supply and general-purpose piping applications. Licensed plumbers and pipefitters install this type of reducer bushing as part of standard threaded pipe work in both residential and light commercial settings.

This hex bushing is appropriate for use in residential and commercial plumbing systems, HVAC piping configurations, and general-purpose threaded pipe runs. The hex outer profile allows for wrench engagement during installation, making it practical in tight spaces where a standard union or coupling would not fit. It is sold in a package quantity of 10, making it suitable for contractors stocking fittings for multiple service calls or installation jobs.

Key Features

• Reduces 3/4-inch female NPT to 3/8-inch male NPT in a single fitting
• Galvanized steel construction resists corrosion in water and general-purpose piping systems
• Hex outer profile allows full wrench engagement for secure installation
• Sold in a package quantity of 10 for contractor-level stocking
• Standard threaded design compatible with NPT pipe systems

Compatibility

Designed as an OEM-style replacement and standard trade fitting for 3/4-inch to 3/8-inch NPT threaded pipe reduction applications in plumbing and HVAC systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a pipe wrench or adjustable wrench sized to the hex profile. Apply thread sealant tape or pipe dope to the male threads before assembly in accordance with local plumbing codes and IPC guidelines. Shut off the water supply or isolate the gas line before disassembling any existing fittings. Do not overtighten threaded fittings, as this can crack galvanized threads and compromise the seal.
