The ASC Engineered Solutions 810088211 is a black malleable iron reducing coupling designed to connect pipe sections of two different diameters in threaded piping systems. At 1-1/2 inches by 1-1/4 inches, this coupling reduces from a larger nominal pipe size to a smaller one using standard threaded connections. The black coating provides corrosion resistance suited to gas distribution, compressed air, and general industrial piping applications. Licensed plumbers and pipefitters typically install this fitting as part of new construction or retrofit work where a diameter change is required in a threaded iron pipe run.
This reducing coupling fits standard threaded malleable iron piping systems commonly found in residential and commercial gas lines, steam systems, compressed air distribution, and industrial process piping. The 1-1/2 inch by 1-1/4 inch size makes it a frequent choice in branch reductions and service line transitions. It is an imported fitting suitable for applications where malleable iron construction meets system requirements.
Designed as an OEM-style replacement or new-install fitting for standard threaded malleable iron pipe systems using nominal 1-1/2 inch and 1-1/4 inch pipe sizes.
Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not overtighten; use pipe wrenches sized appropriately for the fitting to avoid cracking the malleable iron body.
