Rubber oil seals are widely used in various applications due to their versatility, durability, and resistance to oil and other fluids. These seals are designed to provide effective sealing solutions for rotating or reciprocating shafts, preventing the escape of lubricants and the entry of contaminants. Rubber oil seals play a crucial role in maintaining the efficiency and longevity of industrial machinery, automotive engines, and other equipment by ensuring proper lubrication and protection of internal components.
Multiple materials and compounds are used to make oil seals. Some of the oldest materials still used today include felt and leather compounds. However, the trend in mass production has experienced a shift towards synthetic elastomers or rubber.
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.
While Viton offers a superior temperature and chemical range than other materials, it can be more expensive than the others as well. Let’s take a look at an alternative that is easier on the wallet, Polyacrylate.
Offering a much more superior temperature resistance, polyacrylate seals are perfect for applications such as high surface speed oil. Benefits include:
