2. Use environment: PTFE single lip oil Seals are mainly used in environments with no or little dust and impurities, such as indoors or in oil tanks. For example: A-type single-lip oil seal, the speed is up to 30m/s, the filling rate is better, and the PTFE double-lip skeleton oil seal can be used in the working environment with dust and impurities. The dust lip can prevent dust and impurities from entering the cavity, so as not to damage the sealing lip and make the sealing lip lose its sealing effect. Such as type B oil seal, high force up to 30bar, suitable for high pressure environment
