The design of the lip is crucial; its profile allows it to make optimal contact with the shaft, creating a seal that can accommodate the shaft's rotation. Some rotary lip seals also include a dust lip or exclusion barrier, which helps protect the primary sealing lip from contaminants such as dirt and debris.

Furthermore, dust wiper seals help maintain the seal integrity of a system, preventing leaks and ensuring that pressure and fluid levels remain consistent. By creating a tight seal between moving parts, these seals help prevent air and fluid from escaping, which can lead to performance issues and system failure. In hydraulic systems, for example, leaks can result in a loss of power and efficiency, increasing the risk of equipment failure and downtime. Dust wiper seals help prevent these issues by maintaining a secure seal and keeping contaminants at bay.
