Rubber gaskets play an important sealing role in much machinery and equipment. In order to make the gasket perform its normal function and extend its service life, learning correct lubrication operations can achieve these purposes. LindePolymer will introduce you to the key steps and precautions for lubricating rubber gaskets and help you better understand how to lubricate rubber gaskets correctly.

Why do you need to lubricate rubber gaskets?

Rubber gaskets are usually used to seal the gap between the joints of two devices to prevent leakage of fluid or gas within the device. Lubricating rubber gaskets can reduce wear caused by friction to a great extent and ensure the elasticity and sealing performance of the gasket. Suitable Lubrication also reduces friction between the gasket and the mating surface, extending the service life of the gasket.

Choose the right lubricant

  1. Choosing a good lubricant is one of the main steps in lubricating rubber gaskets. Here are some common lubricant choices:
  2. Silicone oil: Silicone oil is a commonly used lubricant with good high temperature resistance and chemical resistance. It provides stable lubrication over a wide temperature range and is compatible with most rubber materials.
  3. Grease: Grease is also a common choice in the lubrication of rubber gaskets. Grease provides long-lasting lubrication and has a high viscosity suitable for use in extrusion or rotational movements.
  4. Water-based lubricants: For some special applications, such as the food processing industry, water-based lubricants may be a more suitable choice. They contain no harmful substances, are environmentally friendly, and are suitable for rubber gaskets that come into contact with food.

Lubrication steps and precautions

  1. Clean the surface: Before lubricating the rubber gasket, make sure the joint surface is clean and free of other grease or impurities, and then use a special solvent to clean the surface.
  2. Apply lubricant evenly: Use an appropriate amount of lubricant and apply it evenly on the surface of the rubber gasket. You can use tools such as a brush, cloth or gloves to apply the lubricant to ensure that the lubricant covers the entire gasket surface.
  3. Avoid excessive lubrication: Excessive lubricant may cause lubricant to penetrate into the inside of the gasket and damage the performance of the gasket itself. Therefore, when applying lubricant, pay attention to controlling the amount of lubricant used to avoid over-lubrication.
  4. Pay attention to the compatibility of lubricants: Different rubber materials may be adapted to different lubricants. When selecting a lubricant, make sure it is compatible with the rubber gasket material to avoid damage to the gasket caused by the lubricant.
  5. Regular inspection and re-lubrication: The lubrication of rubber gaskets should be checked and re-lubricated regularly. According to the usage and working environment, a reasonable lubrication cycle should be developed and ensure that the gaskets are running in a lubricated state.
  6. Pay attention to environmental conditions: Under special environmental conditions, such as high temperature, low temperature, high pressure or corrosive media, special lubricants need to be selected to ensure that the lubricant can provide good lubrication effect and protection under special conditions.
  7. Follow manufacturer recommendations: It is important to follow the advice and guidance of the rubber gasket manufacturer. Different types of rubber gaskets may have specific requirements for lubricants, so be sure to check the instructions provided by the manufacturer if you have questions about this. , also welcome to contact LindePolymer.

In conclusion

Proper lubrication of rubber gaskets is a critical step in ensuring gasket performance and extending their service life. Selecting lubricants that are compatible with rubber gaskets, using correct lubrication procedures, and paying attention to environmental conditions and manufacturer’s recommendations can ensure the good performance of rubber gaskets. Operation and reliable sealing effect. By properly lubricating rubber gaskets, you can increase the efficiency of your equipment, extend the life of your gaskets, and reduce the frequency of maintenance and replacement.
