The MATCO-NORCA mn-ftbu0302 is a forged steel threaded hex bushing used to reduce a 1/2-inch female threaded connection to a 3/8-inch male threaded connection. Forged construction gives this bushing greater structural integrity than cast alternatives, making it suitable for higher-pressure plumbing and piping applications. Plumbers and pipefitters install this type of fitting when two threaded lines of different sizes need to be joined inline. The hex body allows for standard wrench engagement during installation and removal.
This bushing is suited for residential and light commercial plumbing systems where a threaded pipe size reduction is required. Typical applications include water supply lines, gas piping assemblies, and general utility piping where NPT threaded fittings are standard. The 1/2-inch to 3/8-inch reduction is a common transition in both fixture supply and distribution branch lines.
Designed as an OEM-style replacement or direct-use fitting for standard NPT threaded pipe systems requiring a 1/2-inch to 3/8-inch reduction in residential and commercial plumbing or gas piping assemblies.
Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC guidelines depending on the service fluid. Shut off the water or gas supply and depressurize the line before threading this bushing into place. Apply thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use a wrench on the hex body only and avoid applying force to the pipe body.
