The ASC ENGINEERED SOLUTIONS 319905485 is a galvanized steel threaded hex bushing designed to reduce pipe connections from a 1/2-inch female thread to a 3/8-inch male thread. The hex body provides a secure wrench grip during installation, and the galvanized steel construction resists corrosion in both indoor and outdoor service environments. This type of bushing is a standard fitting used by plumbers, pipefitters, and HVAC technicians to adapt between two different pipe thread sizes within a threaded piping system.
This hex bushing is suited for residential and light commercial plumbing, HVAC, and general piping applications where a threaded reduction is needed between 1/2-inch and 3/8-inch NPT connections. It is commonly installed in water supply lines, gas piping assemblies, compressed air systems, and other fluid-handling pipe runs where galvanized steel fittings are appropriate for the service conditions.
Designed as an OEM-style replacement and standard-stock fitting for threaded piping systems requiring a 1/2-inch to 3/8-inch threaded reduction in galvanized steel construction.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Shut off the water, gas, or compressed air supply and relieve system pressure before beginning work. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as this can crack fittings or damage threads.
