B K Mueller 511-953HN Galvanized Hex Bushing 1x1/2 Inch 5-pack

Product Description

The B K Mueller Industries 511-953HN is a galvanized hex bushing used to reduce a 1-inch female pipe thread to a 1/2-inch male pipe thread in steel pipe systems. Hex bushings are a standard fitting for pipe size transitions in gas, water, and general plumbing distribution lines. The galvanized finish provides corrosion resistance suitable for both indoor and outdoor installations. This fitting ships in a pack of 5 units and weighs 1.11 pounds per pack. It is installed by licensed plumbers and pipefitters working on threaded steel pipe assemblies.

This bushing is used in residential and commercial plumbing and mechanical systems wherever a threaded steel pipe requires a reduction from 1-inch to 1/2-inch. Common applications include water supply lines, gas distribution piping, compressed air systems, and hydronic heating systems. The hex design allows the fitting to be tightened and removed with a standard pipe wrench or adjustable wrench without requiring specialty tooling.

Key Features

• Galvanized steel construction for corrosion resistance in wet and outdoor environments
• 1-inch female NPT inlet to 1/2-inch male NPT outlet — standard pipe thread reduction configuration
• Hex body allows wrench engagement for torque-controlled installation
• Sold in a pack of 5 units for service inventory and job-site stocking

Compatibility

Designed as a standard NPT threaded hex bushing for use in threaded steel pipe systems. Compatible with 1-inch female NPT x 1/2-inch male NPT threaded pipe connections in plumbing, gas, and mechanical applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements depending on the service. Shut off and depressurize the pipe system before installing or removing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not overtighten — use a pipe wrench on the hex flats and avoid applying force to the pipe body.
