UKP Piston U-Seal
UKP u-seals are designed to act as a positive sealing, low friction replacement for conventional rubber u-seals. Molded from polyurethane, UKP u-seals provide long life and high resistance against extrusion. Low friction allows these seals to run smoothly in a lubricated or non-lubricated cylinder. Available for bore sealing, the flexible dynamic lip provides very low breakaway friction and steady motion.
