thick rubber gasket. This makes them ideal for outdoor and harsh environment applications where other materials may deteriorate quickly. Additionally, rubber gaskets are non-conductive and can provide an effective barrier against electrical currents, reducing the risk of electrical hazards.
Also, Viton has the widest range of resistance to chemicals. It’s resistant to several chemicals like silicone oil & grease, mineral & vegetable oil, aliphatic, chlorinated hydrocarbons, methanol fuels, and so many more.
Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.
<Seal selection example>
Based on the above flowcharts, the oil seal type that meets the requirements shown in Table 3 would be the type code MHSA or HMSA shown in Table 4.
Generally, an oil seal is made up of an outer circular metal part and a bonded inner flexible material (often nitrile rubber) that does the actual sealing.
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.


Standard Sealing Lip Designs
PTFE material is a perfect ingredient in making more reliable oil seals. These materials are used to make oil seals that can resist dry or unlubricated operations. PTFE oil seals, which are also called teflon oil seals, have a thermal strength ranging from -202 degrees Fahrenheit to 392 degrees Fahrenheit and an excellent chemical resistance. Oil seal PTFE is considered as the future of radial shaft seals.
