The Gripper Gasket Company was established in 1999 to serve as an alternative source for restraining gaskets in the waterworks industry. Gripper Gaskets instantly restrain Tyton Joint® push-on ductile iron pipe, valves, and fittings using steel teeth that eliminate the need for nuts, bolts, clamps, thread rod, retainer glands, concrete thrust blocks, and expensive labor associated with conventional restraining methods.
