An oil seal normally consists of three basic components: the sealing element, the metal case and the spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal case will give rigidity and strength to the seal while it is being held in the bore or recessed groove. The garter spring ensures constant pressure and maintains the radial force to the shaft, flattening the sealing edge to a defined width. The garter spring maintains the radial force exerted by the sealing lip around the shaft surface. All materials must be selected depending on the environment in which the oil seal will function.

It is important to choose the right type of oil seal for a given application, as it may need to address specific operational concerns such as:
In addition to preventing oil leaks, the 30-50-10 oil seal also helps to protect the internal components of the machinery or equipment from dirt, dust, and other contaminants. This extends the lifespan of the machinery and ensures its optimal performance.
Motor oils typically include a few additives which can make up between 5% and 30% of the oil. These additives help enhance the performance of the oil. Motor oils can include the following additives:
