The ASC Engineered Solutions 390202083 is a Gruvlok grooved end flanged adapter designed to connect grooved piping systems to flanged components. This fitting serves as a transition point between grooved-end pipe and standard flanged equipment such as pumps, valves, and other inline devices. At 5 inches by 10 inches, it is sized for larger-diameter commercial and industrial piping runs. Licensed plumbers, pipefitters, and mechanical contractors install this adapter in hydronic, fire protection, and general mechanical piping systems where a secure, leak-resistant grooved-to-flange transition is required.
This adapter is suited for commercial and industrial mechanical systems where grooved piping meets flanged equipment connections. Typical applications include HVAC hydronic loops, chilled water systems, fire suppression headers, and plant utility piping. The grooved end accepts a standard Gruvlok-compatible coupling, while the flanged end bolts directly to mating flanged components. This fitting is intended for larger-diameter piping installations where a reliable grooved-to-flange interface is needed.
Designed as an OEM-style grooved end flanged adapter for use with Gruvlok-compatible grooved piping systems in commercial and industrial mechanical applications.
Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes. Depressurize and drain the piping system completely before removing or installing any grooved or flanged fittings. Verify that the mating flange bolt pattern and pressure rating are compatible before assembly. Inspect the grooved end of the pipe for proper groove dimensions and condition prior to installing the coupling.
