Description:
A U-Cup Seal is a type of hydraulic seal used to prevent fluid leakage between two surfaces, typically a piston and a cylinder wall. It is designed to exert a sealing force against the cylinder wall as the piston moves back and forth, creating a tight seal between them.

Attributes:
• Designed with grooves, which help provide a secure location for the seal.
• Helps to reduce friction between the piston and cylinder wall.

Applications;
A  U-Cup Seal is used to provide a secure and reliable connection between the components, mostly used in Cat 320B, 320C, 322B, 322C, 324D, 325B, 325C, 330B, 330C, 345B, 5080, and M325C Excavators, 980, 980K, 980L, 980M and 982M Wheel Loaders, D10 and D10T Track Type Tractors, M325D Material Handlers.
