Double Lips - Oil seals work by creating a tight seal around a rotating shaft or axle, preventing oil or other fluids from leaking out. They typically have a spring or a flexible lip that applies pressure to the shaft, creating a barrier that keeps the oil inside the machinery. The material used to make oil seals is resistant to oil, heat, and pressure, ensuring that they can withstand the harsh conditions present in many types of machinery.

Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
