The ASC Engineered Solutions 321200073 is a straight tapped galvanized steel coupling designed for use in pipe joining applications across plumbing, HVAC, and mechanical systems. The fitting measures 1-1/2 inches and provides a threaded, straight-through connection between two pipe sections of the same nominal diameter. The galvanized steel construction offers corrosion resistance suitable for general-purpose pipe systems. This coupling is installed by licensed plumbers and pipefitters as part of new construction or repair work on threaded pipe runs.
This coupling is suited for residential and light commercial piping systems where a straight tapped threaded connection is required. It is used in water supply lines, hydronic heating systems, and other mechanical piping applications that call for a standard 1-1/2-inch threaded coupling. The tapped design accepts male-threaded pipe ends on both sides, making it a straightforward choice for connecting pipe sections in a single run.
Designed as an OEM-style replacement or standard fitment for 1-1/2-inch threaded pipe systems in residential and commercial mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IPC guidelines. Shut off water supply and depressurize the line before removing or installing pipe fittings. Apply appropriate thread sealant or PTFE tape to male threads before making up the connection. Do not over-tighten threaded joints, as this can damage the fitting or the mating pipe threads.
