Basic information:

Oil seal is often called grease, fluid, dirt or lip seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment. In most applications, the seal is either partially or temporarily immersed or is simply exposed to splashing lubricant, particularly in engines, transmissions, gearboxes or axles. They are vital components of almost every type of machine and vehicle in operation. An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts.

Fluororubber properties: 

Standard color: brown

Excellent resistance to mineral oils, aliphatic and aromatic hydrocarbons, as well as hydrocarbons containing chlorine,  concentrated and dilluted acids, weak alkalis. Its excellent heat resistance (up to +200°C), as well as cold resistance (-30°C),  depending on the type of seal, along with its good mechanical properties and remarkable aging resistance, place fluororubber well above the traditional synthetic rubbers. It is especially suitable for high peripheral velocity applications. 

Advantages: 

- excellent heat resistance within a wide temperature range: from -30°&#; to 200 °&#;

- superior resistance to oil and fuels as compared to other rubber types

- the only highly elastic rubber which is resistant to aromatic and chlorinated hydrocarbons
