  • A valve cover gasket, whether it's at the front or rear, serves as a barrier, maintaining the integrity of the engine's oil system. It seals the space where the valves, rocker arms, and pushrods operate, keeping oil from seeping out and contaminants from creeping in. The rear valve cover gasket, specifically, is situated behind the cylinder head, typically in engines with overhead valves or camshafts.
  • One of the key advantages of sheet gaskets is their flexibility and adaptability. They can easily conform to irregular surfaces and provide a tight seal, ensuring that no fluid or gas can escape. This makes them ideal for use in a wide range of industries, including automotive, aerospace, oil and gas, and manufacturing.

  • PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of  -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.

  • 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.

  • Another significant benefit of iridium spark plugs is their ability to produce a more consistent spark. This is because iridium has a lower electrical resistance than other metals commonly used in spark plug construction. As a result, iridium spark plugs can deliver a stronger and more reliable spark, which is essential for optimal engine performance.
  • Rubber O.D. wall
  • Acrylate rubber also has many other excellent properties - ozone resistance, 
  • The front valve cover gasket is a critical component in an engine that helps prevent oil leaks and ensures proper lubrication of the engine's moving parts. It is responsible for sealing the gap between the front valve cover and the cylinder head, keeping oil from leaking out and dirt from getting in.
  • The quality of the power steering oil seal is also a critical factor in its performance

  • Different Types of Oil Seals

  • The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.

  • One of the key benefits of using 40mm rubber gaskets is their durability. These gaskets are designed to withstand constant exposure to harsh conditions without deteriorating. They are resistant to corrosion, UV rays, and ozone, making them ideal for outdoor applications. Additionally, the flexibility of rubber allows the gasket to conform to irregular surfaces, ensuring a complete and secure seal.
  • Soft materials (brass and so on) are not suitable.
  • Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.

  • DIN

  • ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.

  • In conclusion, gasket automation has come a long way from its manual roots. The integration of automated machinery has not only streamlined the production process but also elevated the standard of gaskets used in various applications. As technology continues to advance, we can expect further enhancements that will drive gasket manufacturing towards even greater heights of efficiency and sustainability.
