Asc Engineered Solutions 390213210 Rigid Coupling 3 in

Product Description

The ASC ENGINEERED SOLUTIONS 390213210 is a Gruvlok 74CL Sabertooth painted rigid grooved coupling designed for use with 3-inch grooved-end pipe. It incorporates a CenterLok EPDM gasket that self-centers within the coupling housing during assembly, reducing installation time and improving joint consistency. Built from ductile iron, the coupling delivers the mechanical strength required for rigid piping systems in commercial and industrial applications. At 5.94 pounds, the assembly is substantial and suited for permanent, movement-free pipe joints. Licensed pipefitters and mechanical contractors typically specify this coupling where system rigidity and grooved-end piping are required.

The 390213210 is intended for 3-inch grooved-end piping systems in commercial HVAC, fire protection, plumbing, and industrial process piping. The rigid design prevents angular and linear movement at the joint, making it appropriate for systems where pipe alignment must be maintained. The CenterLok EPDM gasket is suited for cold and hot water service as well as diluted acid and alkaline solutions within the temperature range appropriate for EPDM compounds. This coupling is commonly installed in mechanical rooms, vertical risers, and horizontal mains where system integrity and pressure retention are critical.

Key Features

• Rigid coupling design prevents pipe movement at the joint for fixed-alignment piping systems
• CenterLok EPDM gasket self-centers in the housing for consistent sealing and simplified installation
• Ductile iron construction provides high tensile strength and impact resistance
• Factory-painted finish offers corrosion protection suitable for mechanical room and above-ground installations
• 3-inch nominal size fits standard grooved-end pipe in that diameter

Compatibility

Designed as an OEM-style grooved rigid coupling for use with standard 3-inch grooved-end pipe prepared to AWWA or standard roll-groove specifications.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor familiar with grooved piping systems. Shut down system pressure and drain the line before disassembling or replacing any grooved coupling. Verify that pipe ends are properly grooved to the correct profile and are free of burrs, debris, and out-of-round conditions before seating the CenterLok gasket. Tighten coupling bolts evenly and in alternating sequence to ensure uniform gasket compression and proper housing engagement.
