Asc Engineered Solutions 318905569 Hex Bushing 1/2x1/8

Product Description

The ASC ENGINEERED SOLUTIONS 318905569 is a black steel threaded hex bushing designed to reduce pipe thread sizes in pressurized piping systems. It transitions a 1/2-inch female NPT connection down to a 1/8-inch male NPT connection, allowing technicians to adapt pipe runs, branch lines, or instrument taps where a size reduction is required. The hex body provides a flat wrench surface for secure installation without pipe-wrench marring. Weighing 0.11 pounds, this compact fitting is a standard item in gas, water, and compressed-air piping assemblies across residential and commercial applications.

This hex bushing is used wherever a threaded pipe size reduction is needed inline. Common applications include gas supply lines, compressed-air distribution, hydronic heating systems, and steam piping. HVAC technicians, plumbers, and pipefitters install this type of fitting when connecting smaller-diameter instruments, gauges, or branch piping into a larger main line. It is suited for both new construction and retrofit piping work.

Key Features

• Black steel construction for durability in gas and piping service environments
• Threaded hex body style allows standard wrench engagement during installation
• 1/2-inch female NPT inlet to 1/8-inch male NPT outlet for inline size reduction
• Compact and lightweight at 0.11 pounds
• Compatible with standard NPT threaded pipe systems

Compatibility

Designed as an OEM-style replacement or standard fitting for threaded NPT piping systems requiring a 1/2-inch to 1/8-inch reduction in residential and commercial gas, water, or compressed-air applications.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians following applicable code requirements such as the IFGC or IPC. Shut off and depressurize the piping system before installing or replacing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten; use a calibrated torque approach with a proper fitting wrench to avoid thread damage.
