Galvanized Fittings 12x18bu Hex Head Reducing Bushing 1/2x1/8 in

Product Description

The GALVANIZED FITTINGS 12x18bu is a hex head reducing bushing that steps down a 1/2-inch female threaded port to a 1/8-inch male threaded connection. Constructed from galvanized steel and rated at Class 125, this bushing is built for low-pressure piping systems where corrosion resistance and a secure threaded fit are required. The hex head design allows for standard wrench engagement during installation, reducing the chance of slippage or fitting damage. Plumbers, pipefitters, and HVAC technicians reach for this type of bushing when adapting between mismatched pipe sizes in water, air, or gas distribution lines.

This reducing bushing is suited for residential and light commercial piping applications. It is commonly installed in water supply lines, compressed air systems, and low-pressure gas piping where a reduction from 1/2-inch to 1/8-inch is needed at an inline or dead-end connection point. The galvanized finish provides added protection against rust in moderately humid or wet environments, making it a practical choice for mechanical rooms, utility spaces, and exposed pipe runs.

Key Features

• Reduces 1/2-inch female threads to 1/8-inch male threads in a single fitting
• Hex head design allows firm wrench engagement for leak-free makeup
• Galvanized steel construction resists corrosion in wet and humid environments
• Class 125 pressure rating suitable for low-pressure water, air, and gas service
• Threaded end connections conform to standard NPT fitting practices

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 125 threaded galvanized steel piping systems requiring a 1/2-inch to 1/8-inch reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the service type. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; snug plus one to two turns with a wrench is standard practice for threaded NPT connections.
