The ASC Engineered Solutions 321200289 is a 2-inch taper tapped galvanized steel coupling designed for joining threaded pipe sections in mechanical and plumbing systems. The taper tapped thread profile creates a secure, pressure-bearing connection that tightens as the fitting is driven onto mating pipe threads. Galvanized steel construction provides corrosion resistance suitable for water, gas distribution, and general industrial piping applications. This coupling is installed by licensed plumbers and pipefitters working on both new construction and retrofit projects where a reliable threaded pipe joint is required.
This fitting is suited for residential and light commercial piping systems where 2-inch threaded galvanized steel pipe is used. Common applications include water supply distribution, gas lines, and mechanical room piping. The taper tapped design is a standard configuration across a wide range of pipe fitting assemblies, making this coupling a practical replacement or new-installation component in systems that call for galvanized threaded fittings.
Designed as a standard OEM-style replacement or new-installation fitting for 2-inch threaded galvanized steel pipe systems in residential and commercial plumbing and mechanical piping applications.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and local mechanical codes. Shut off and depressurize the pipe system fully before removing or installing any threaded fittings. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly to ensure a leak-free joint. Do not overtighten, as this can crack the fitting or distort the threads.
