The ASC Engineered Solutions 390037067 is a Gruvlok 7076 series grooved-by-male-pipe-thread (MPT) painted concentric reducer designed for mechanical pipe joining systems. This fitting transitions from a 2.5-inch grooved end to a 2-inch male threaded end, allowing technicians to connect grooved piping to threaded pipe or threaded equipment connections in a single fitting. Constructed from ductile iron and finished with a red paint coating for corrosion identification, this reducer is installed by licensed pipefitters and mechanical contractors working on fire protection, HVAC, or industrial piping systems where grooved coupling technology is specified.
This reducer is suited for both commercial and industrial piping applications where a grooved mechanical joint system meets a threaded connection point. It is commonly used at equipment inlets and outlets, headers, and branch takeoffs where flow reduction is required between a 2.5-inch grooved main and a 2-inch threaded port. The concentric design keeps the pipe centerlines aligned, which is important in horizontal runs where drainage or flow consistency is a concern.
Designed for use in Gruvlok 7076 series grooved piping systems as an OEM-style grooved-to-threaded transition fitting for 2.5-inch grooved pipe to 2-inch MPT connections.
Installation should be performed by a qualified pipefitter or mechanical contractor familiar with grooved coupling systems and threaded pipe joining per applicable mechanical codes. Depressurize and drain the piping system fully before removing any existing fittings or couplings. The grooved end requires a compatible grooved coupling for assembly; do not substitute couplings rated for different pipe schedules or pressure classes. Ensure the MPT threads are sealed with an appropriate thread sealant rated for the fluid and pressure service before torquing to connection.
