TECHNICAL DATA SHEETS TECHNICAL DATA SHEETS GRUVLOK GASKET-STYLES Gruvlok offers a variety of pressure responsive gasket styles. Each serves a specific function while utilizing the same basic sealing concept. Proper installation of the gasket compresses the inclined gasket lips on the pipe O.D., forming a leak tight seal. This sealing action is reinforced when the gasket is encompassed and compressed by the coupling housings. The application of internal line pressure energizes the elastometric gasket and further enhances the gasket sealing action. “C” STYLE The “C” Style cross section configuration is the most widely used ® gasket. It is the gasket style provided ROUGHNECK as standard in many Gruvlok Couplings This “C” style gasket is (Fig. 7000, 7001, 7003, 7004HPR, 7307, similar in appearance 7400 and 7401). Grade “E” and “T” are standard grades while other grades and design to the are available for special applications. Standard gasket but is only used with Fig. 7005 ™ END GUARD Roughneck Couplings The projecting rib fits between the ends and Fig. 7305 HDPE Couplings. The Roughneck gasket is wider, which allows of lined pipe to prevent damage to for minor pipe end separation as line pressure sets the grippers into the unprotected pipe ends during coupling plain end pipe. joint assembly. The E.G. gasket is provided as standard with the Fig. 7004 E.G. Coupling. REDUCING COUPLING Grade “E” and “T” gaskets are available. The centering rib allows for pipe positioning and serves FLUSH GAP™ to keep the smaller pipe from telescoping during installation. Designed to prohibit contaminates Used only with the Fig. 7010 from building up in the gasket cavity. Reducing Coupling. The centering rib fits flush over the gap between the two pipe ends thus closing off the gasket cavity. It can be used with Fig. 7000, 7001, 7400 and 7401 Couplings for many applications. FLANGE Recommended for use in dry fire protection systems. A specially designed gasket for the Fig. 7012, 7013 ™ and 7312 Flange provides for a reliable seal on SLIDELOK PRESSURE RESPONSIVE both the pipe and the mating flange. SlideLOK gasket patent pending design easily slides over the grooved pipe end for quick installation. The gasket design provides a 360˚ consistent compression seal when fully installed. The internal ribs are design to prohibit contaminants from building in the gasket cavity CLAMP-T™ by engaging individually with each pipe end. These gaskets conform to the SOCK-IT® curved exterior of the pipe to provide a pressure responsive Used in Sock-It fittings only, this seal. This unique design is only pressure energized gasket provides a used with Fig. 7045, 7046 Clamp-T leak-tight seal on plain end seal pipe. and Fig. 7047, 7048, and 7049 Available in Grade “E” material only.
