U-Cup Seal

U-Cup Seal, 22X30X5.7

The MRTU-22X30X5.7 U-Cup Seal is a twin-lip urethane rod seal engineered for high-pressure hydraulic applications. Molded from tough urethane, this seal features an additional secondary lip positioned farther from the heel (VME design) to improve stability, retain lubrication, and block contaminants. Designed to handle demanding operating conditions, it provides reliable sealing performance up to 5,000 PSI.
