Asc 390002988 Gruvlok Grooved Coupling 1-1/2 in Ductile Iron

Product Description

The ASC Engineered Solutions 390002988 is a standard grooved coupling from the Gruvlok 7001-E series, designed to join grooved-end pipe in mechanical piping systems. Constructed from ductile iron, this coupling provides a rigid, pressure-rated connection at the 1-1/2 inch pipe size. It is a staple fitting in commercial and industrial piping installations where grooved mechanical joining is specified over welded or threaded connections. Licensed plumbers, pipefitters, and mechanical contractors routinely install Gruvlok-style couplings on fire protection, HVAC hydronic, and process piping systems.

This 1-1/2 inch grooved coupling is suited for use in both new construction and retrofit applications where grooved pipe joining systems are already in place. Typical installations include hydronic heating and cooling distribution, fire suppression mains, and industrial process piping. The coupling engages the grooved ends of prepared pipe and is secured with the included hardware to form a sealed, mechanically sound joint.

Key Features

• Ductile iron construction for strength and durability in mechanical piping applications
• 1-1/2 inch fitting size for standard grooved-end pipe
• Standard grooved coupling style compatible with grooved pipe joining systems
• Compact and lightweight at 1.55 pounds for easier handling in tight spaces
• Part of the Gruvlok 7001-E series for consistent fitment across grooved system components

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch grooved-end piping systems using standard groove dimensions.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or mechanical contractors. Depressurize and drain the piping system completely before disassembling or installing any grooved coupling. Inspect the pipe groove profile to confirm it meets the standard groove specification before assembly. Follow applicable codes including NFPA 13 for fire protection systems and local mechanical codes for hydronic or process piping.
