Purpose of an Oil Seal

4. Use the right gasket material When replacing a gasket, make sure to use the correct material that is compatible with your engine's specifications. Using the wrong material can lead to leaks and engine damage.
3. Compression set Compression set is the permanent deformation that occurs when a material is subjected to constant pressure over a period of time. High temperature rubber gaskets have low compression set, which ensures that they maintain their shape and seal effectively over time. When it comes to the type of plug, there are two main categories conventional spark plugs and performance spark plugs. Conventional spark plugs are designed for everyday driving and are relatively inexpensive, while performance spark plugs are designed for high-performance vehicles and can be much more expensive.

Installation tips for oil seals

Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.

Polyacrylate (ACM) Oil Seals

The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.
