The ASC ENGINEERED SOLUTIONS 810088807 is a black malleable iron reducing coupling designed for connecting pipes of two different sizes in threaded piping systems. This fitting reduces from a 1-1/2 inch connection to a 1/2 inch connection and is finished with a black coating. Malleable iron construction provides the strength and ductility needed to handle mechanical stress and vibration common in commercial and industrial piping installations. Plumbers and pipefitters install this type of fitting in gas distribution, compressed air, and black iron piping systems where a concentric inline reduction is required.
This reducing coupling is suited for residential and light commercial applications involving black iron pipe systems, including natural gas supply lines, propane distribution, and compressed air piping. The 1-1/2 inch by 1/2 inch sizing makes it a practical choice for branch reductions and service connections within a threaded pipe assembly. All connections are threaded, consistent with standard NPT fitting practice.
Designed as an OEM-style replacement or standard service fitting for threaded black iron pipe systems using 1-1/2 inch and 1/2 inch NPT connections.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the application. Shut off and depressurize the line completely before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
