Table 1: The order of priority for selecting oil seals
2. The most common types of oil seals are rubber-cased and metal-cased.
2, oil seal lightweight, fewer supplies. Each type of oil seal is a combination of thin-walled metal parts and rubber parts, and its material consumption is very small so that each oil seal has a lightweight.
When installing a product, people often ignore the instructions because there is an idea that we can do it ourselves. However, oil seals are fragile devices that require attention and specific instructions to be followed before and after use.
Mechanical seals, like oil seals, can be easily damaged during installation. Taking the time to read the installation manual will provide you with step-by-step information on the correct installation or replacement of oil seals.
How do oil seals work?
A final step in preparation for assembly is to lubricate the shaft, sealing lip and bore with sufficient oil. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. Always use oil or grease that is compatible with the oil seal material. In addition, when sliding over the shaft, the oil seal comes into contact with the keyway, threads and grooves. 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.
(the volume of oil, etc., pushed back at the lip contact area per unit of time)
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.

- Rubber pipe gaskets are essential components in plumbing systems that help create a watertight seal between two pipes or between a pipe and a fitting. These gaskets are typically made from durable rubber materials that have excellent resistance to water, chemicals, and high temperatures. The primary function of a rubber pipe gasket is to prevent leaks and ensure a secure connection between pipes, which is crucial for maintaining the integrity of the plumbing system.
