The ASC Engineered Solutions 321200305 is a 3-inch taper tapped threaded galvanized steel coupling designed for joining pipe sections in mechanical and plumbing piping systems. The taper-tapped thread configuration creates a tighter, more secure seal as fittings are torqued together, reducing the risk of leaks at the joint. Galvanized steel construction provides corrosion resistance suitable for wet or exposed installations. This type of coupling is a standard component used by licensed plumbers and pipefitters working on water distribution, industrial piping, and general mechanical systems.
This coupling is suited for residential and commercial piping applications where a galvanized steel threaded fitting is required. It is appropriate for use in water supply lines, fire protection rough-in, and other systems calling for a 3-inch taper tapped threaded connection. Installation follows standard pipe fitting practices and applicable codes.
Designed as an OEM-style replacement and standard-fit coupling for 3-inch threaded galvanized steel piping systems following NPT thread standards.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code. Shut off and depressurize the system before disassembling existing fittings or installing new ones. Use appropriate pipe thread sealant or PTFE tape on all threaded connections. Do not overtighten, as this can crack or deform the fitting threads.
