The ASC Engineered Solutions 320201049 is a 3/4 inch extra heavy taper tapped coupling designed for steel pipe systems in demanding industrial and commercial plumbing applications. Constructed from black steel, this fitting accepts tapered thread connections and is rated as extra heavy duty for higher-pressure service conditions. The taper tap design ensures a secure, thread-engaged joint that resists loosening under vibration or pressure cycling. Licensed plumbers and pipefitters install this type of coupling when joining threaded black steel pipe runs where standard-weight fittings are not sufficient for the application.
This coupling is suited for use in commercial and industrial piping systems where black steel pipe is specified, including gas distribution, steam, and high-pressure fluid lines. The extra heavy wall classification makes it appropriate for systems operating beyond the pressure limits of standard or Schedule 40 fittings. It is typically installed in mechanical rooms, boiler rooms, and process piping environments where code compliance and joint integrity are critical.
Designed as an OEM-style replacement and standard fitting for 3/4 inch threaded black steel pipe systems in commercial and industrial plumbing or gas piping installations.
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 all gas or fluid supply and depressurize the line before making or breaking any threaded connections. Apply thread sealant or PTFE tape rated for the service type to all male threads before assembly. Do not overtighten, as this can crack or deform the fitting.
