Gruvlok Figure 7305 HDPE Rigid Coupling
Gruvlok® Figure 7305 HDPE Rigid Coupling
The Gruvlok® Figure 7305 HDPE Rigid Coupling is an innovative mechanical pipe coupling engineered to provide a secure, rigid connection for High-Density Polyethylene (HDPE) pipe without the need for heat fusion or specialized joining equipment. Designed as a cost-effective alternative to fusion welding, the Figure 7305 significantly reduces installation time while providing exceptional joint strength and long-term reliability. The coupling is compatible with HDPE pipe manufactured to ASTM F714, ASTM D2447, ASTM D3000, and ASTM D3035, with wall thicknesses ranging from SDR 32.5 through SDR 7.3.
Ideal for municipal water systems, mining operations, wastewater treatment plants, irrigation systems, industrial process piping, and utility infrastructure, the Figure 7305 delivers a dependable mechanical connection while eliminating the expense and complexity of fusion equipment.
Innovative Mechanical HDPE Joining
Secure Rigid Connection Without Fusion
The Gruvlok® Figure 7305 utilizes a robust four-bolt mechanical design that drives precision-machined gripping teeth into the exterior surface of the HDPE pipe. Once engaged, the teeth create a rigid mechanical connection with pressure capabilities that can exceed the pressure rating of the HDPE pipe itself. Unlike fusion methods, installation is quick, straightforward, and does not require heat, electricity, or specialized operator certification.
The gripping teeth are strategically positioned away from the gasket to maximize sealing performance while minimizing stress on the sealing surface throughout the operating temperature range.
Low-Profile Housing Design
Built for Easy Installation and Relocation
The Figure 7305 features a low-profile contoured ductile iron housing with molded exterior ramps that allow assembled pipelines to slide more easily over obstacles during installation or relocation. This unique design improves handling of long HDPE pipe sections while protecting the coupling from damage during field operations.
Its rugged construction makes the coupling well suited for demanding industrial environments where durability and ease of maintenance are essential.
Ideal Applications
Reliable Performance Across Multiple Industries
The Gruvlok® Figure 7305 HDPE Rigid Coupling is widely specified for water transmission, mining slurry systems, irrigation networks, municipal infrastructure, wastewater treatment facilities, industrial processing plants, and utility piping where HDPE pipe is preferred for its corrosion resistance and flexibility.
