The ASC Engineered Solutions 390013522 is a Gruvlok 7401-E Rigidlok grooved painted coupling designed for rigid pipe joining in mechanical piping systems. At 2.5 inches, this coupling clamps onto roll-grooved or cut-grooved pipe ends to create a secure, rigid joint without welding or threading. Constructed from ductile iron with a painted finish for corrosion resistance, it suits high-pressure and structurally demanding piping runs. Licensed plumbers, pipefitters, and mechanical contractors typically install this fitting in commercial and industrial applications where joint rigidity and system integrity are required.
This coupling is suited for use in commercial HVAC piping, fire suppression systems, industrial process piping, and plumbing distribution where a rigid grooved-end connection is specified. The 2.5-inch size accommodates standard grooved pipe of the same nominal diameter. It is commonly installed in locations where vibration isolation is not a concern and a fixed, rigid joint is preferred over a flexible grooved coupling.
Designed as a rigid grooved coupling for 2.5-inch nominal grooved pipe in commercial and industrial mechanical piping systems conforming to standard grooved-end pipe dimensions.
Installation is typically performed by licensed pipefitters or plumbers following applicable mechanical codes such as the IPC or ANSI/AWWA groove standards. Shut down and depressurize the piping system completely before removing or installing any grooved coupling. Inspect pipe groove dimensions for conformance before assembly and verify the gasket is properly seated before tightening housing bolts evenly. Do not overtighten bolts beyond the coupling manufacturer hardware specifications provided in the product installation sheet.
