Gruvlok Grade T Nitrile Gasket
Gruvlok® Figure 7004 High Pressure Rigid Coupling with Grade "T" Nitrile Gasket
The Gruvlok® Figure 7004 High Pressure Rigid Coupling with Grade "T" Nitrile Gasket is a heavy-duty mechanical grooved coupling engineered for high-pressure piping systems handling petroleum-based fluids. Combining the installation efficiency of grooved piping with the strength of a rigid mechanical joint, the Figure 7004 delivers working pressure ratings up to 1,200 PSI (82.7 bar) when installed on grooved standard wall steel pipe. Designed for applications where pipe movement is undesirable, the coupling creates a rigid connection that prevents expansion and contraction while maintaining precise pipe alignment.
Equipped with a Grade "T" Nitrile gasket, the Figure 7004 is ideally suited for oil and gas production, petroleum processing, hydraulic systems, compressor stations, industrial manufacturing, mining operations, auto and truck wash systems, and elevator hydraulic services.
High-Pressure Performance
Engineered for Rigid Pipe Connections
The Gruvlok® Figure 7004 provides the versatility and ease of installation associated with grooved piping systems while delivering the structural integrity required for demanding industrial applications. Its rigid design withstands high operating pressures and is especially effective in systems subjected to pressure surges and pressure pulses, helping maintain system stability and equipment alignment.
The coupling installs quickly on roll-grooved or cut-grooved standard wall steel pipe, eliminating the need for welding, threading, or flanged joints and significantly reducing installation time and labor costs.
Grade "T" Nitrile Gasket
Designed for Petroleum-Based Fluids
The Grade "T" Nitrile (Buna-N) gasket, identified by its orange color code, is manufactured in accordance with ASTM D2000 and offers a service temperature range of -20°F to 180°F (-29°C to 82°C). It is specifically recommended for petroleum products, mineral oils, vegetable oils, hydraulic fluids, lubricating oils, fuels, and compressed air containing oil vapors.
The Grade "T" gasket provides outstanding resistance to petroleum-based media while maintaining dependable sealing performance under high-pressure operating conditions. It is not recommended for hot water or hot air applications, where EPDM or other specialized gasket materials should be used.
