Hydraulic u cup seals are mainly known for their design, shaped like the letter “U” in cross-section. U seals’ main function is to prevent medium leakage and withstand certain pressure and temperature changes. They achieve the sealing effect by pressing the lip of one side of the U-shape tightly against the sealing contact surface through the pressure generated by the liquid or gas.
TYS is a u cup seals supplier that offers metric hydraulic u cup seals, including piston cup seals and u cup rod seal,they are made of polyurethane 、nitrile or proprietary PTFE materials, with the advantages of high resistance to extrusion deformation, high wear resistance and not easy deform, which can adapt to dynamic and static sealing requirements and ensure high sealing performance.

When the medium in the system is pressurized, the U-sealing lip is close to the piston rod. The sealing ability is more vital as the pressure increases. U cup rod seals are mainly used in hydraulic cylinders and pneumatic cylinders. When the piston rod reciprocates, it is sealed to prevent leakage of fluid medium. U cup rod seals are primarily made of polytetrafluoroethylene/polyurethane/nitrile or elastic materials. The specific material is selected according to the actual application environment. Choose TYS to choose a tailor-made U cup rod seal for your particular needs.
