Gruvlok Figure 7003 Hingelok Coupling
Gruvlok® Figure 7003 Hingelok® Coupling
The Gruvlok® Figure 7003 Hingelok® Coupling is a specialized mechanical grooved coupling engineered for piping systems that require rapid connection and disconnection without sacrificing safety or reliability. Designed for applications involving frequent maintenance, equipment servicing, or temporary piping installations, the Figure 7003 allows technicians to quickly remove and reconnect piping while minimizing downtime. With working pressure ratings up to 300 PSI (20.7 bar), the Hingelok® Coupling is ideal for industrial processing, mining, water treatment, mechanical systems, temporary bypass piping, manifold systems, and maintenance-intensive facilities.
Unlike conventional grooved couplings, the Figure 7003 features permanently hinged housing halves and a tool-free locking mechanism that significantly reduces installation time while providing a secure, leak-resistant mechanical pipe joint.
Quick Installation with Hinged Design
Fast Connection and Disconnection
The Gruvlok® Figure 7003 features permanently hinged coupling halves that remain connected during installation, making handling easier and reducing the risk of misplaced components. A durable cam-action locking handle securely closes the coupling over the pipe grooves, allowing rapid assembly without the need for additional tools.
For added convenience, 1-inch through 4-inch sizes utilize toggle link plates, while 5-inch through 8-inch sizes incorporate a toggle bolt to attach the cam-action handle. Once closed, a locking pin is installed to provide an additional level of security, ensuring dependable performance in critical piping applications.
Reliable Performance for Maintenance Applications
Designed for Frequent Service
The Figure 7003 Hingelok® Coupling is specifically engineered for installations where piping must be disconnected on a regular basis for equipment maintenance, cleaning, inspection, or system modifications. Its innovative design dramatically reduces labor time while maintaining the strength and leak resistance expected from Gruvlok® mechanical piping products.
The coupling is compatible with standard grooved piping systems, providing a dependable mechanical connection without the need for welding, threading, or flanged joints.
