- Nitrile Rubber (NBR): This is the most frequently used material for sealing elements, boasting good heat resistance properties and resistance to salt solutions, oils, hydraulic oils, and gasoline. Its recommended operating temperature range is from -40 to 248°F (-40 to 120°C). Nitrile functions adequately in a dry environment but only for intermittent periods.
- The '7 ' component in the title refers to the oil seal's rubber compound, which typically consists of a percentage of oil. This oil content imparts flexibility and resilience to the seal, allowing it to maintain its integrity under varying temperatures and pressures. It enhances the seal's ability to adapt to the surface irregularities of the shaft, ensuring a tight seal even in dynamic conditions.
- 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.
Leather Oil Seals
Improper installation can cause your oil seal to malfunction. While being tapped into place, it can become tilted or misaligned in the bore. That being said, setting it up correctly will help ensure that the sealing process is effective.
How Oil Seals

If you’re committed to preserving your vehicle for the long run, stick to regularly scheduled preventative maintenance services, especially oil changes with high mileage oil.

Oil seals are typically classified based on their sealing capabilities, with common types including lip seals, mechanical seals, and hydraulic seals. Lip seals are the most basic type, consisting of a flexible lip that seals against the shaft. Mechanical seals use sliding or rotating components to create a seal, while hydraulic seals are designed for high-pressure applications.
