In addition to preventing fluid loss, oil seals also protect machinery from external contaminants such as dust, dirt, and moisture. These particles can cause significant damage if they enter the inner workings of equipment. The presence of a well-functioning oil seal eliminates this risk, fostering a clean operational environment.

In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from damage.

The temperature within the oil seal environment is the main factor that dictates the composition of an oil seal. Generally, there is a range of set temperatures that are optimal for that material. If the operating environment is too cold, the seal may become brittle and, at high temperatures, the seal material may show increased elasticity and become leaky.
