Hydraulic cylinders work by utilizing pressurized fluid to create motion. In the context of an engine hoist, they control the vertical movement necessary for lifting heavy engines out of vehicles. Given the weight and potential danger associated with these operations, a well-functioning hydraulic cylinder is essential.

Oil seals, commonly known as rotary shaft seals, are devices that prevent the leakage of lubricants while keeping contaminants such as dirt and moisture out. High temperature variants are designed to operate effectively in environments where standard seals would typically fail due to thermal degradation. These seals are made from materials that can withstand elevated temperatures, such as silicone, fluoroelastomers (FKM), and polyurethane.

The technological advancements in oil seal manufacturing also play a significant role in their pricing. Innovations leading to improved performance—such as better wear resistance, enhanced sealing capabilities, or longer service life—may allow manufacturers to charge a premium for high-quality seals. Conversely, if a more affordable, efficient sealing solution is developed, it can disrupt existing pricing structures, leading to lower prices for conventional oil seals.
