DESCRIPTION

The R-4 u-cup is a specialized rod seal design, developed from the standard symmetrical u-cup. It assures improved sealing performance due an interference fit in the groove that prevents movement of the seal during cylinder operation. With an improved lip design, the dynamic sealing lip has a heavier cross-section for improved high pressure capability.
