The MATCO-NORCA igma04 is a 3/4-inch steel insert male adapter designed for use in piping systems where a threaded male connection is needed at the transition point of an insert-style fitting. Constructed from steel, this adapter provides a durable mechanical connection suitable for residential and light commercial plumbing and piping applications. It is typically installed by licensed plumbers or pipefitters during new construction or repair work involving insert-type fittings joined to threaded pipe connections.
This adapter is suited for use in supply line and distribution piping systems that incorporate insert-style fittings. The 3/4-inch size makes it a common choice for branch lines and main supply connections in both residential and light commercial installations. It is compatible with standard 3/4-inch insert fitting systems and male threaded pipe connections of the same nominal size.
Designed as an OEM-style replacement or new-installation fitting for standard 3/4-inch insert-style piping systems with male threaded connections.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before beginning work. Ensure mating threads and insert ends are clean and free of debris before assembly. Do not overtighten threaded connections, as this may damage the fitting or the mating component.
