The ASC ENGINEERED SOLUTIONS 319905642 is a galvanized steel threaded hex bushing used to reduce a larger female pipe thread to a smaller male pipe thread. The external hex head allows for wrench engagement during installation, ensuring a secure, leak-resistant connection. This fitting transitions a 3/4-inch female thread to a 3/8-inch male thread and is built from galvanized steel for corrosion resistance in wet or exposed environments. It is a standard component used by plumbers, pipefitters, and HVAC technicians in a wide range of piping assemblies.
This hex bushing is suited for residential and light commercial plumbing, gas piping, HVAC condensate and supply lines, and general pipe fitting applications where a threaded reduction is needed. It is installed wherever a pipe or fitting with a 3/4-inch female NPT thread must connect to a 3/8-inch male NPT outlet. The galvanized finish makes it appropriate for indoor or outdoor installations where moisture exposure is a factor.
Designed as an OEM-style replacement or standard-service fitting for threaded pipe systems requiring a 3/4-inch to 3/8-inch reduction in plumbing, HVAC, or gas piping applications.
This fitting is installed by licensed plumbers or HVAC technicians in accordance with applicable local plumbing or mechanical codes. Shut off the water supply or gas line and depressurize the system before installation. Apply thread sealant or PTFE tape to the male threads before making up the joint. Do not overtighten, as this can crack the fitting or damage mating threads.
