Coat the flange with gasket sealant, then carefully fit the flat parts of the gasket. - In conclusion, oil seal manufacturing is a complex and precise endeavor, requiring a deep understanding of materials, engineering, and quality control. It is a testament to human ingenuity and the relentless pursuit of perfection in even the smallest components that keep our machines running smoothly. From the initial mixing of raw materials to the final product, every step is critical in ensuring the reliability and longevity of oil seals in the demanding environments they serve.
When choosing a type of oil seal, it is important to consider factors such as environment, shaft speed and pressure of your machine, temperature, and the type of materials the seal will interact with during use. These considerations will ensure that you choose a compatible oil seal for your particular machinery and help you select the right color, size, and lip material or sealing element.
Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.

PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.
3. Fluid types: Oil seals interact with oils, fuels, grease, water, and more. Choosing a seal material that is most compatible with your chosen medium can help to increase the durability of the seal and its internal components.
