Asc Engineered Solutions 390003143 Grooved Coupling 8 in

Product Description

The ASC Engineered Solutions 390003143 is a standard grooved coupling designed for use in grooved piping systems. Part of the Gruvlok 7001-E series, this coupling joins grooved-end pipe sections by securing over the pipe grooves with a gasket and housing to create a rigid, pressure-rated connection. Constructed from ductile iron, it is built to handle the mechanical demands of commercial and industrial piping applications. At 8 inches, this is a large-diameter fitting intended for main distribution lines in mechanical systems. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers.

This standard grooved coupling is used in commercial and industrial piping systems where grooved-end pipe joining is specified. Common applications include fire suppression mains, HVAC hydronic distribution piping, and industrial process piping. The 8-inch size is suited for high-flow trunk lines and primary distribution runs in large mechanical systems. It is typically installed in new construction and retrofit projects where grooved piping is the preferred joining method for speed and ease of assembly.

Installation Notes

Installation is performed by licensed pipefitters or plumbers in accordance with applicable mechanical and plumbing codes. Depressurize and drain the piping system fully before disassembly or installation of any grooved coupling. Proper gasket seating and bolt torque are essential to achieving a leak-free joint — follow the manufacturer installation instructions for fastener sequence and seating confirmation. At 20.29 pounds, use appropriate lifting technique or mechanical assistance when handling this fitting overhead or in confined spaces.
