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.
