液压 U 形杯密封件主要以其横截面形似字母 "U "的设计而闻名。U 型密封件的主要功能是防止介质泄漏和承受一定的压力和温度变化。它们通过液体或气体产生的压力，将 U 形的一侧唇缘紧压在密封接触面上，从而达到密封效果。
TYS是一家 U 形杯密封件供应商 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.
Choose the u ring seals and loaded u cup seals for efficient system operation you need from the following products:
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.
