What Is a Piston Seal?
A piston seal is a component used to prevent fluid leakage within a cylinder.
Made of rubber, ring-shaped seals are commonly used to fill the gap between the piston and cylinder bore, maintaining a sealed condition.
They are employed in hydraulic cylinders and pneumatic cylinders to prevent leakage of oil or air and to prevent foreign matter from entering from the outside.
Piston seals are essential components for maintaining the performance of machinery and enabling safe operation.
Defects such as the degradation of piston seals can lead to machine malfunction and safety issues, making them critical components.
