- Next, you'll need to disconnect the battery to avoid any accidental electrical sparks. Then, locate the valve cover, which is usually a large metal or plastic cover atop the engine. Start removing any bolts or screws securing the cover, using a socket wrench or screwdriver, depending on the type. Be cautious not to strip the threads or damage the cover.
There are a wide variety of industrial applications and therefore there are a wide variety of oil seals to meet the specific application needs. By choosing the right oil seal you will have a better fit, improved stability, and enhanced reliability. Rubber tends to be one of the most commonly used oil seal materials. an oil seal manufacturer, explains how oil seals for and the importance of proper installation, “To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. The shaft counterface surface and housing bore should meet the demands specified in the sections Shaft requirements and Housing bore requirements. To facilitate seal installation and to achieve initial lubrication, prior to installation, recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.
When selecting oil seals for wheel hubs and steering mechanisms, it is essential to prioritize quality, durability, and compatibility with specific vehicle models. High-quality oil seals are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality oil seals is crucial to ensure the reliability and longevity of these critical components.
Polytetrafluoroethylene
Chemical resistant
Low coefficient of friction poor elastic properties not wear resistant if used by dynamic applications
Orient your seal the same way as the initial install.The sealing lip should face the lubricant that requires sealing.The second lip on a double lip oil seal is intended as a dust lip. The seal must be installed at a 90°, or perpendicularly, to both the shaft and housing bore. This is an issue in cases where the housing does not have a counterbore or shoulder the seal can seat up against.
By first finding out the dimensions of the inner and outer diameters and the height of the bore, you have all the data for the correct size of the oil seal. Of course, the oil seal must also be able to withstand the pressure, temperature and medium it is exposed to within the seal during the manufacturing process. You can read more about this in our oil seal selection guide.
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.

Propylene (fluorinated ethylene)
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.
