UH05 / U641 hydraulic seals with heat-resistant urethane material are designed for cylinder sealing and operate in extreme temperature ranges for long service life under severe and extended operation (e.g., construction equipment). UHO5 seals are rated for –30° to 120°C and U641 are rated for –20° to 110°C. They offer strong resistance against degraded (waste) oil and heat with almost no permanent deformation. Elastomeric properties allowing for rapid restoration in low temperatures, ensuring stable sealing in cold applications.
