When it comes to choosing the right oil seal for a particular application, there are several factors to consider. One of the key aspects is the material used in the construction of the seal. Different materials offer varying levels of resistance to heat, chemicals, and wear, so it is essential to select a seal that can withstand the specific conditions it will be exposed to.
- Oil seals are fundamental components in the operation of machinery, providing a vital barrier between the internal lubricated areas and the external environment. These seals are specifically designed to prevent the leakage of oil or other fluids from the sealed chamber, while also preventing contaminants from entering. The rubber material used in their construction plays a crucial role in determining the performance, durability, and longevity of these seals.
The oil seals represent the most important type of dynamic sealing on rotating shafts. During the last years, we witnessed a great evolution in the technology, starting from their shape to the materials used nowadays.
Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

Polyacrylate oil seals are a perfect compromise between quality and cost. They perform well with high temperatures and chemicals, but not as well as Viton oil seals. Polyacrylate has a temperature range of -25 degrees Fahrenheit to 300 degrees Fahrenheit. Due to their outstanding resistance to hot oil and oxidation, they are commonly used in automobile transmissions and hoses; however, they are also used for shaft seals, gaskets, and o-rings.
