  • Regular maintenance and inspection of the oil seal are essential to ensure its continued effectiveness. Any signs of wear or damage should be addressed promptly to prevent oil leaks and potential damage to the machinery or equipment.


  • Die-cut rubber gaskets offer several advantages over other sealing materials, such as flexibility, resilience, chemical resistance, and thermal stability
  • One of the key advantages of PU oil seals lies in their chemical resistance. They can effectively resist degradation from exposure to a wide range of chemicals, including oils, greases, solvents, and even some acids. This property not only extends the lifespan of the seal but also prevents contamination of the machinery, ensuring consistent performance.

  • A wide range of industries rely on oil seals to ensure optimal operation of mechanical assemblies. Components in the industrial and automotive fields, such as pumps, fans, electric motors, and other rotating or moving parts, use oil seals to maintain lubrication and keep contaminants from entering the shaft. Seals are especially useful in applications exposed to extreme environmental temperatures and pressures.

  • Regular maintenance is key to preventing issues with the valve cover gasket on an LS3 engine. It is recommended to check the gasket for wear and tear during routine oil changes and replace it as needed. Additionally, keeping the engine clean and free of debris can help extend the life of the gasket.

  • Remember, always consult your owner's manual or a professional mechanic before performing any engine modifications or replacements. Improper installation or maintenance can lead to engine damage and other safety issues.

  • 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.
