Asc 390013563 Gruvlok 7401-E Rigidlok Grooved Coupling 6 in

Product Description

The ASC Engineered Solutions 390013563 is a 6-inch RigidLok grooved coupling designed for rigid pipe joint connections in mechanical piping systems. Built from ductile iron with a painted exterior finish, this coupling clamps onto grooved pipe ends to create a secure, zero-flex joint. At 8.05 pounds, it is sized for heavier-duty applications where pipe movement must be fully restrained. Licensed mechanical contractors and pipefitters install this type of coupling in commercial and industrial settings where grooved piping systems are specified over threaded or flanged alternatives.

The 390013563 rigid grooved coupling is used in commercial HVAC hydronic systems, fire protection piping, industrial process lines, and mechanical rooms where rigid joint performance is required. The grooved end connection method speeds up installation compared to welded or flanged joints, making it a common choice on new construction and retrofit projects. This coupling fits 6-inch grooved pipe prepared to standard groove specifications.

Key Features

• Rigid coupling design restrains angular and linear pipe movement at the joint
• Ductile iron construction for strength and durability in pressurized piping
• Painted exterior finish provides basic corrosion protection during installation and service
• 6-inch nominal pipe size fits standard grooved pipe ends
• Grooved connection method reduces installation time versus flanged or welded joints

Compatibility

Designed as an OEM-style rigid grooved coupling for 6-inch grooved pipe systems in commercial HVAC, fire protection, and industrial piping applications.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor familiar with grooved piping systems. Shut down and depressurize the piping system completely before removing or installing any coupling. Verify that pipe ends are cut and grooved to the correct dimensions for the 6-inch coupling before assembly. Follow the manufacturer torque specifications on the housing bolts and inspect the gasket seating before returning the system to service.
