Pneumatic & Hydraulic U-Cup Seals

U-Cup Seals are used to seal hydraulic fluid (hydraulic U-Cup Seals) or air (pneumatic U-Cup Seals), which helps create the pressure necessary for the hydraulic and pneumatic power systems to work.

U-cup seals are used in hydraulic cylinders for piston or rod applications in equipment that relies hydraulic or pneumatic power. Many construction and off-road vehicles use hydraulic and/or pneumatic power: backhoes, front-loaders, tractors, cranes, bull dozers and forklifts. Manufacturers also rely on U-cup seals for equipment that utilizes hydraulic or pneumatic power.
