The ASC ENGINEERED SOLUTIONS 318905726 is a black steel threaded hex bushing used to reduce pipe thread size in piping systems. It transitions a 3/4-inch female NPT connection down to a 1/8-inch male NPT connection, allowing techs to connect components with mismatched thread sizes without adding extra fittings. The hex body provides a solid grip point for wrenches during installation. At 0.21 pounds, it is a compact, heavy-duty fitting suited for use in gas, air, and fluid distribution lines. Plumbers, pipefitters, and HVAC technicians install this type of bushing as a standard part of threaded piping assemblies.
This bushing is used in residential and commercial applications wherever a threaded pipe system requires a size reduction at a fitting, valve, or equipment port. Common install scenarios include connecting pressure gauges, sensors, or valved branches to larger main lines. The black steel construction makes it appropriate for gas piping, compressed air systems, and non-potable water lines where corrosion resistance demands of black iron are acceptable.
Designed as a standard threaded hex bushing for use in black steel NPT piping systems requiring a 3/4-inch to 1/8-inch reduction at threaded connections.
Installation is performed by licensed plumbers, pipefitters, or HVAC technicians working on threaded piping systems. Shut off gas supply or depressurize the line before threading or unthreading any fitting. Apply appropriate thread sealant or PTFE tape to NPT threads per local code requirements before installation. Refer to IFGC or IPC guidelines for thread engagement and pressure testing requirements in your jurisdiction.
