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.

Allied Metrics produces U-Cups in a variety of rubber, Teflon and urethane. No order is too small or too large, and we regularly accommodate needs of just a few U-Cups to orders of thousands.

Below is a list of the types that we offer.  For profiles not listed below, please call us for availability.
