high temperature oil seal
The sealing lip is designed to conform to the shaft, creating a tight barrier that minimizes fluid escape
. Depending on the application, rotary shaft seals can be designed for various shaft diameters and operating conditions, including temperature extremes and high pressures.Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.
dust seal vs oil seal

The mechanics of a door base draught excluder are quite straightforward. When a door is closed, the draught excluder creates a seal that minimizes or completely blocks any airflow through the gap beneath the door. This sealing action helps maintain the internal temperature of a room by preventing drafts that can lead to uncomfortable chilling in winter and excessive heat loss. In the summer months, draught excluders can also help keep cool air in and warm air out, thus enhancing the effectiveness of air conditioning systems.
