Gruvlok Figure 7401 RidgeLOK Rigid Coupling
Gruvlok® Figure 7401 RidgeLOK® Rigid Coupling
The Gruvlok® Figure 7401 RidgeLOK® Rigid Coupling is a premium mechanical grooved coupling engineered to provide a secure, rigid pipe connection for commercial and industrial piping systems. Designed with Gruvlok's advanced GuideLOK® housing technology, the Figure 7401 delivers superior pipe engagement, simplified installation, and dependable long-term performance. It is an ideal solution for HVAC systems, fire protection, mechanical piping, industrial processing, water distribution, manufacturing facilities, and commercial plumbing where rigid pipe support and precise alignment are essential.
The Figure 7401 is compatible with roll-grooved and cut-grooved standard weight steel pipe, roll-grooved lightweight steel pipe, grooved-end fittings, and valves. When installed on standard wall roll- or cut-grooved pipe, it provides working pressures up to 750 PSI (51.7 bar) while supporting rigid pipe hanging practices in accordance with ASME B31 Pipe Codes.
Advanced GuideLOK® Housing Technology
Fast Installation with Positive Pipe Engagement
The Gruvlok® Figure 7401 features a technologically advanced housing that conforms to and firmly grips the pipe for maximum joint integrity. Installation is simple and efficient—only one nut needs to be removed before swinging the housing over the gasket and into the pipe grooves.
The exclusive GuideLOK® feature automatically separates the grooved pipe ends and accurately guides the coupling into position as the bolts are tightened. Precision-engineered housing tines securely engage the pipe grooves, producing a rigid mechanical joint that resists movement while maintaining proper pipe alignment.
Built for Rigid Mechanical Piping Systems
Reliable Performance for Commercial and Industrial Applications
The Figure 7401 RidgeLOK® Coupling is designed for installations where pipe movement is undesirable. Its rigid connection eliminates expansion and contraction at the joint while providing excellent structural support for suspended piping systems. By eliminating welding, threading, and flanged joints, the coupling significantly reduces installation time, labor costs, and future maintenance requirements.
Its versatility makes it an excellent choice for mechanical rooms, industrial plants, municipal water systems, commercial buildings, power generation facilities, and manufacturing operations.
