Asc 390000305 Gruvlok 7000-E Grooved Coupling 3 Inch

Product Description

The ASC Engineered Solutions 390000305 is a Gruvlok 7000-E lightweight grooved coupling designed for mechanical pipe joining in commercial and industrial piping systems. Constructed from ductile iron, this 3-inch coupling connects grooved-end pipe sections without welding or threading, making it a fast, reliable choice for fire protection, HVAC hydronic, and general plumbing installations. At 3.05 pounds, the lightweight design reduces installer fatigue during overhead and high-volume work. Licensed pipefitters, fire sprinkler contractors, and mechanical contractors are the typical installers for this type of fitting.

This coupling is suited for 3-inch grooved pipe connections in wet and dry systems across a range of commercial and industrial applications. Typical installations include chilled water and hot water hydronic loops, fire suppression mains, and process piping where grooved mechanical joining is specified. The 7000-E series is a recognized grooved coupling configuration used in projects requiring rigid or flexible pipe joint methods depending on system design requirements.

Key Features

• Ductile iron construction for strength and impact resistance in demanding piping environments
• 3-inch grooved pipe connection for fast mechanical joining without welding or threading
• Lightweight design at 3.05 pounds reduces handling fatigue during multi-coupling installations
• Compatible with standard roll-grooved and cut-grooved pipe ends per industry groove dimensions
• Suitable for fire protection, HVAC hydronic, and industrial piping applications

Compatibility

Designed as an OEM-style grooved mechanical coupling for 3-inch grooved-end pipe in fire protection, HVAC, and industrial piping systems where standard grooved coupling dimensions apply.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified mechanical contractor in accordance with applicable codes including NFPA 13 for fire suppression systems or applicable mechanical codes for HVAC and plumbing. Depressurize and isolate the pipe section before disassembly or coupling installation. Ensure pipe ends are properly grooved to the correct depth and width before seating the gasket and housing. Do not overtighten bolts unevenly — follow a cross-pattern bolt tightening sequence to seat the housing uniformly around the gasket.
