Auto oil seals are integral to the functionality of various automotive components, including the engine, transmission, and wheel assemblies. These seals are designed to contain lubricating oil and prevent leaks, contributing to the efficient operation and longevity of the vehicle. Proper maintenance and replacement of auto oil seals are essential to ensure the reliability and performance of the vehicle's systems.
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.



Rubber gaskets, commonly used in various industrial applications, serve the purpose of preventing oil leakage and maintaining the integrity of machinery by creating a barrier between two or more components.
To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.

Minor lip The minor lip prevents the entry of dust and contaminants from outside.
Lubricant can be retained in the space between the main lip and the minor lip.

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.
