The History and Applications of Oil Seals
- There are several different types of mechanical oil seals available, each designed for specific applications and operating conditions. Some common types include lip seals, labyrinth seals, and mechanical face seals, each offering unique benefits and features to meet the needs of different industries and equipment.

There are a variety of oil seals used in a variety of applications to help close the space between a stationary and a moving part. By closing the space it prevents any lubricants from escaping. Additionally, oil seals help create a seal that prevents any contaminants from entering machinery which can cause a host of problems. Mechanical equipment and machinery require different size or type oil seals to ensure that there is a superior and precise seal. Because oil seals help reduce contamination or mixing of materials it prolongs the life of machinery and helps ensure a more reliable performance.
