Conversely, an oil seal, also referred to as a fluid seal or grease seal, is primarily designed to retain lubricants such as oil or grease within a specific area. Oil seals are crucial in preventing the leakage of lubricants from machinery, thereby ensuring optimal lubrication and efficient operation. They are also essential in preventing contaminants from entering these lubricated compartments.

A hydraulic cylinder packing kit consists of various seals and gaskets designed to prevent fluid leakage and ensure optimal performance of hydraulic cylinders. These kits serve as barriers between the high-pressure hydraulic fluid and the external environment, thus protecting the system from contaminants and maintaining operational efficiency. Packing kits come in various designs and materials, depending on the specific application and operating conditions.

2. Quality of Materials High-quality seal kits made from durable materials, such as polyurethane or fluorocarbon, offer better performance and longevity compared to cheaper alternatives.
