The MATCO-NORCA mn-ftbu0300 is a forged steel threaded hex bushing designed to reduce pipe thread sizes in plumbing, gas, and mechanical piping systems. It features a 1/2-inch male NPT end and a 1/8-inch female NPT end, allowing technicians to transition between two common pipe sizes within a single fitting. The hex body provides wrench flats for secure tightening with standard hand tools. Forged construction delivers the strength and pressure resistance required for demanding trade applications.
This hex bushing is suited for use in residential and light commercial plumbing, gas distribution, and mechanical piping installations where a threaded reduction is needed between a 1/2-inch and 1/8-inch NPT connection. It is commonly installed by licensed plumbers, pipefitters, and HVAC technicians when connecting gauges, sensors, or smaller-diameter fittings to standard pipe runs.
Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded pipe systems requiring a 1/2-inch to 1/8-inch reduction.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements for the piping system type. Shut off the gas or water supply and relieve system pressure before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten, as forged steel fittings can damage mating threads if excess force is applied.
