Hydraulic seals are essential components in hydraulic systems, designed to prevent fluid leakage and maintain pressure within machinery. These seals are typically made from flexible, non-metallic materials and are carefully fitted into grooves or combined with other rings to form a seal assembly. Their primary function is to control the movement of fluid, ensuring it remains contained in applications involving reciprocating motion. Hydraulic seals play a crucial role in converting fluid power into linear motion, making them indispensable in various types of machinery. They are crafted from materials such as polyurethane, rubber, or PTFE, selected based on the specific requirements of the operating environment. Factors like fluid type, pressure, chemical compatibility, and temperature all influence the choice of material.
