Asc Engineered Solutions 390213208 Rigid Coupling 2.5 in

Product Description

The ASC ENGINEERED SOLUTIONS 390213208 is a grooved rigid coupling designed for 2.5-inch pipe systems. Known as the Gruvlok 74CL Sabertooth, this painted rigid coupling uses a CenterLok EPDM gasket to deliver a secure, leak-resistant connection at grooved pipe joints. Fabricated from ductile iron, the coupling provides reliable structural strength in demanding piping applications. It is a field-proven choice for mechanical contractors and pipefitters working on commercial and industrial piping systems where rigid joint performance is required.

The 390213208 is suited for commercial and industrial piping installations, including HVAC hydronic systems, fire protection piping, and general mechanical piping. The rigid coupling design prevents angular deflection at the joint, making it appropriate for systems that require straight, fixed pipe runs. The CenterLok gasket design helps center the gasket during assembly, reducing installation errors and improving joint reliability. Licensed mechanical contractors and pipefitters typically install this fitting during new construction and retrofit projects.

Key Features

• Ductile iron construction for high-strength, durable performance in mechanical piping systems
• Rigid coupling design prevents angular deflection, maintaining fixed pipe alignment
• CenterLok EPDM gasket self-centers during assembly to reduce installation error
• Painted finish provides basic corrosion protection for indoor and sheltered applications
• Grooved-end connection compatible with standard grooved pipe and fittings at 2.5 inches

Compatibility

Designed as an OEM-style grooved rigid coupling for use with standard 2.5-inch grooved-end pipe in commercial and industrial mechanical piping systems.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor familiar with grooved piping systems. Shut off and depressurize the piping system completely before disassembly or coupling installation. Inspect the pipe groove and gasket seat for damage before assembly, and apply the appropriate gasket lubricant to the EPDM gasket prior to installation. Follow the manufacturer torque guidelines for coupling bolts as referenced in the product installation sheet.
