Piston Seals

Piston seals or piston rings are used in hydraulic cylinders for fluid sealing. They are placed inside the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build-up on one side of the piston, making the cylinder extend or retract.
