Oil seals are indispensable parts for sealing all types of equipment. They have a number of features such as simple structures, relatively low cost, and usability across a wide range of environmental conditions. Approx. 40 large and small oil seals are employed in automobiles.
An oil seal consists of three parts: a synthetic rubber part, a metal ring, and a spring.
