Polyurethane oil seals are mainly used in hydraulic cylinders, which are easy to install and can scrape off dust adhering to the piston rod. The green polyurethane oil seal has slightly lower hardness, while the blue one has higher hardness and can withstand greater pressure. Polyurethane oil seals have excellent physical and mechanical properties, wear resistance, and oil resistance, making them suitable for the most demanding working conditions. They effectively prevent the entry of external impurities, thereby achieving excellent sealing performance. They are the most commonly used sealing components in medium and high pressure hydraulic cylinders.

Polyurethane oil seal is a sealing component made of this material. Sealing refers to a device that prevents fluid leakage by maintaining contact and relative sliding between at least one pair of end faces perpendicular to the rotational axis under the action of fluid pressure, compensation mechanism elasticity (or magnetic force), and auxiliary sealing.
