��$�� p �s�a �� a�� s�� The instructions are based on pipe grooved in accord nce with Gruviok°grooving specifications.Check pipe ends for proper groove dimensions and to assure that the pipe ends are ree of indentations and projections which would prevent proper sealing. ALWAYS USE A GRUVLOK�L.UBRICANT FOR PROPE COUPLING ASSEMBLY.Thorough lubrication of the external surface of the gasket is essential to prevent pinching and Po sible damage to the gasket. For temperatures above 150°F use Gruvlok XtremeT"' Lubricant and lubricate all gasket urfaces, internal and external.See Gruvlok Lubricants in the Technical Data section of the Gruvlok catalog for ad itional important information.
