The ASC Engineered Solutions 321200040 is a straight tapped galvanized steel coupling designed for joining threaded pipe sections in a wide range of piping systems. Built from galvanized steel, this coupling provides corrosion resistance suited for use in demanding trade environments. At 3/4 inch fitting size and weighing 0.26 pounds, it is a compact and reliable component for connecting pipe runs where a tapped straight coupling configuration is required. Licensed plumbers, pipefitters, and mechanical contractors rely on this type of fitting for building and maintaining code-compliant piping assemblies.
This coupling is used in residential and light commercial plumbing, HVAC hydronic piping, and general mechanical piping systems where 3/4 inch galvanized steel fittings are specified. The straight tapped design allows threaded pipe ends to be joined inline, making it a standard component in water supply, drainage, and mechanical system pipework where galvanized steel is the material of choice.
Designed as an OEM-style replacement or standard-use fitting for 3/4 inch threaded galvanized steel pipe systems in plumbing and mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system before beginning any fitting work. Use appropriate pipe thread sealant or tape on all threaded connections to ensure a leak-free joint. Do not overtighten fittings, as this can damage threads or crack the fitting body.
