The ASC ENGINEERED SOLUTIONS 319906764 is a galvanized iron hex bushing designed to reduce pipe thread size in plumbing and mechanical piping systems. This fitting transitions from a 1-inch female thread to a 3/8-inch male thread, allowing installers to connect pipes or components of different sizes within the same line. The galvanized coating provides corrosion resistance for use in standard water supply, gas distribution, and general mechanical piping applications. The hex body allows for wrench engagement during installation. Weighing 0.18 pounds, it is a domestically manufactured fitting suited for trade and commercial work.
This hex bushing is used in residential and commercial plumbing, HVAC hydronic systems, gas piping, and industrial mechanical applications where a threaded size reduction is required. It is installed by licensed plumbers, pipefitters, and HVAC mechanics in situations where a larger-diameter pipe or fitting must connect to a smaller-diameter component. The 1-inch by 3/8-inch size combination is common in branch line reductions and equipment connection points.
Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded piping systems requiring a 1-inch to 3/8-inch threaded reduction.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable codes such as the IPC or IFGC depending on the service. Shut off and depressurize the piping system fully before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten iron fittings, as cracking or thread damage can result.
