Seal up wide gaps with our metal reinforced high pressure seal! Perhaps one of the most distinctive features on this PU seal is the trapezoidal metal reinforcement that surrounds the inner ring. Thanks to these reinforcements, the hydraulic seal can hold up well against high pressure encountered during hydrostatic pressure test. We currently supply these metal reinforced high pressure seals in two types, coded by English letter C and D. Type C seals larger gaps than type D. Seals of the same size can accommodate a wide range of steel pipe diameters. We are looking forward to your bulk orders.
