Asc Engineered Solutions 390000388 Grooved Coupling 5 in

Product Description

The ASC Engineered Solutions 390000388 is a lightweight grooved coupling designed for use in piped mechanical systems. Part of the Gruvlok 7000-E series, this fitting connects grooved-end pipe sections quickly and securely without welding or threading. Constructed from ductile iron, it offers reliable strength in a reduced-weight form factor suited for overhead or high-density piping layouts. At 5 inches, it fits standard grooved pipe of that nominal diameter. Licensed plumbers, pipefitters, and mechanical contractors install this type of coupling in commercial and industrial piping systems where speed of assembly and ease of future disassembly are priorities.

The 390000388 is used in commercial and industrial mechanical piping applications where grooved-end pipe connections are specified. Typical installations include HVAC hydronic systems, fire protection piping, and general process piping. The lightweight design reduces installer fatigue and structural load in overhead pipe runs. This coupling is suited for both new construction and retrofit projects where grooved mechanical joining is the preferred or specified method.

Key Features

• Lightweight grooved coupling design reduces weight versus standard ductile iron couplings
• Ductile iron construction provides high tensile strength and impact resistance
• 5-inch nominal size fits standard grooved-end pipe of that diameter
• Tool-free pipe removal and re-entry without cutting or threading
• Part of the Gruvlok 7000-E series for consistent fit with compatible gaskets and hardware

Compatibility

Designed as an OEM-style grooved mechanical coupling for use with standard 5-inch grooved-end pipe in commercial and industrial piping systems.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes. Depressurize and drain the piping system fully before servicing or installing grooved couplings. Verify that pipe ends are properly grooved to the correct specification before assembly. Follow the manufacturer torque sequence for housing bolts to ensure even gasket seating.
