The difference between PTFE single lip oil seal and double lip oil seal

The difference between PTFE single lip oil seal and double lip oil seal is as follows:

1, structure: PTFE single lip skeleton oil seal only a single sealing lip, double lip oil seal seal and dustproof two lips. Both oil seals are made of tetrafluoroPTFE material, good wear resistance and corrosion resistance, and long service life.

2, the use of the environment: PTFE single-lip oil seal is mainly used for no or little dust and impurities in the environment, such as indoors or in the tank. For example: Type A single-lip oil seal, the speed is as high as 30m/s, the filling rate is better, PTFE double-lip skeleton oil seal can be used for dust and impurities in the working environment, dust lip can prevent dust and impurities from entering the chamber, so as not to destroy the sealing lip and make the sealing lip lose the sealing effect. For example, Type B oil seal, high force up to 30bar, suitable for high-pressure environments.
