- Despite their many advantages, sheet gaskets do have some limitations. For example, they are not as resilient as other types of gaskets, such as metal gaskets, and may need to be replaced more frequently. Additionally, sheet gaskets are more prone to creep and relaxation over time, which can compromise their sealing performance.
- The superiority of NBR as a sealing material stems from its molecular structure, which combines the durability of butadiene with the chemical resistance of acrylonitrile. This blend creates a resilient elastomer that can operate effectively in applications spanning from automotive engines to hydraulic systems in heavy machinery. Its elastic properties ensure a tight fit, preventing leaks and prolonging the lifespan of machinery by minimizing maintenance requirements.
Silicone compounds or “VMQ” offers a wide range of traditional operating temperatures starting at -60°C to 200°C (-140°F to 392°F).
With the application cleaned and the components ready, you’ll begin your installation.
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
To ensure correct fit and proper protection against contaminants, the inside diameter of an oil seal must be slightly smaller than the shaft diameter.

Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:
