2. Contamination Control Hydraulic oil is susceptible to contamination from dust, dirt, and other external particulates. Seals act as barriers, keeping harmful substances out of the hydraulic system. This is essential for prolonging the life of hydraulic fluid and components, such as pumps and actuators.

The main function of hydraulic piston seal kits is to prevent the hydraulic fluid from escaping the system, which can lead to a loss of pressure and efficiency. By creating a tight seal around the piston, these kits ensure that the fluid remains contained within the system, allowing for smooth and reliable operation of the hydraulic equipment.

Hydraulic cylinders operate on the principle of Pascal's Law, which states that pressure applied to a confined fluid is transmitted undiminished throughout the liquid. Engine hoists typically use these cylinders to lift engines and other heavy components by converting hydraulic pressure into linear motion. However, constant use can lead to issues such as leaks, reduced lifting power, and eventually, cylinder failure.

The design of a cylinder gland seal varies according to factors such as the type of fluid, pressure levels, and temperature ranges. Common materials used for these seals include elastomers, such as nitrile rubber, polyurethane, and PTFE (Teflon). Each material has specific properties that make it suitable for particular applications. For example, PTFE seals are excellent for high-temperature applications due to their thermal resistance, while nitrile rubber is effective for a wide range of hydraulic fluids.
