Gruvlok Figure 7004 High Pressure Rigid Coupling
Gruvlok® Figure 7004 High Pressure Rigid Coupling
The Gruvlok® Figure 7004 High Pressure Rigid Coupling is a premium mechanical grooved coupling engineered to provide the installation advantages of a grooved piping system while delivering the strength and stability of a rigid pipe joint. Designed for demanding commercial and industrial applications, the Figure 7004 provides working pressure ratings up to 1,200 PSI (82.7 bar) when used on grooved standard wall steel pipe. Its rugged construction and rigid design make it an excellent choice for high-pressure process piping, hydraulic systems, elevator services, industrial manufacturing, mining operations, water transfer systems, and commercial vehicle wash facilities.
Unlike flexible couplings, the Figure 7004 creates a rigid mechanical joint that prevents pipe expansion and contraction, maintaining precise alignment throughout the piping system while reducing movement under pressure.
Built for High-Pressure Applications
Rigid Performance with Grooved Pipe Technology
The Gruvlok® Figure 7004 combines the versatility and ease of installation of a grooved coupling with the performance required for high-pressure service. It is specifically designed to withstand demanding operating conditions, including systems that experience frequent pressure pulses or pressure surges.
The coupling is especially well suited for auto and truck wash systems, hydraulic piping, pump discharge lines, and elevator hydraulic services, where high operating pressures require dependable joint integrity. Working pressure and end-load ratings are based on properly prepared grooved standard wall steel pipe.
Fast Installation and Long-Term Reliability
Eliminate Welding and Threading
The Figure 7004 installs quickly on compatible roll-grooved or cut-grooved steel pipe without the need for welding, threading, or flanged connections. This significantly reduces installation time, minimizes labor costs, and simplifies future maintenance or system modifications.
Its rigid mechanical design also supports accurate pipe alignment, making it an excellent solution for systems where movement could affect equipment performance or piping stability.
