In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.

The oils seals require certain prerequisites to be maintained for their proper working. They are as follows:
Clean sediment out of the sump with petrol and a stiff brush . Dry with a lint-free cloth.
Why are sealed bearings favored over the unsealed alternative? Why ought sealed ball bearings be preferred to unsealed ones? What advantages can sealed ball bearings offer?

oil tank gasket.
Another type of seal design has the metal encased in rubber (Figure 2.11).
Oil seals come in a vast range of materials and compounds. Even older materials, such leather, are still used today. Nitrile is among the most common materials for oil seals but is slowly losing ground to PTFE, which is gaining popularity due to its effectiveness in high-speed applications.
Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
