Hebei Hankai high pressure oil rail seal kit

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.

2. Fluid Quality Always use the appropriate hydraulic fluid, and ensure that it is clean and free of contaminants.

An oil seal, often referred to as a fluid seal, is a device that seals the interface between two components, preventing the leakage of oils or lubricants. Oil seals are typically made from elastomeric materials that provide flexibility, resilience, and resistance to wear and tear. They are essential for ensuring the proper functioning of machinery by minimizing contamination from external elements and retaining lubricants within the system.
