The ASC ENGINEERED SOLUTIONS 320201072 is a 1-1/2 inch Extra Heavy black steel taper tapped coupling designed for demanding pipe joining applications. This fitting accepts tapered threads and provides a secure, rigid connection in high-pressure or heavy-duty piping systems. Constructed from black steel, it delivers the wall thickness and strength required for extra heavy service classifications. Licensed plumbers and pipefitters install this coupling in commercial and industrial systems where standard-weight fittings are not rated for the application.
This coupling is suited for use in commercial plumbing, industrial process piping, and mechanical systems that specify extra heavy black steel fittings. The taper tapped design conforms to standard pipe thread geometry, making it appropriate for gas distribution lines, fire suppression headers, steam systems, and other high-demand piping configurations where a reliable threaded joint is required. It is sized at 1-1/2 inches to fit corresponding schedule pipe and fittings in that nominal size.
Designed as an OEM-style replacement and standard-stock fitting for extra heavy black steel threaded piping systems using 1-1/2 inch nominal pipe.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply appropriate thread sealant or tape to tapered threads before assembly and tighten to a snug fit using pipe wrenches sized for the application. Do not overtighten, as this can crack or distort the fitting body.
