  • The key to F6TC Spark Plug's success lies in its unique design and functionality. It incorporates a high-performance battery that stores energy generated during the combustion process. This stored energy can then be released instantly when needed, providing a boost of power that enhances engine performance and efficiency.
  • When installing a 38x52x7 oil seal, it is important to ensure that the seal is properly lubricated and aligned with the shaft. This will help to minimize friction and wear, and extend the life of the seal. It is also important to regularly inspect the seal for any signs of damage or wear, and replace it if necessary to prevent oil leakage.


  • Oil seals are widely used as sealing devices for machines.

    JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
    However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.

    Therefore, this series of columns will summarize the following in order:
    • The structure, functions, and types of oil seals
    • How to select the right oil seal
    • Handling of seals, and causes and countermeasures for oil seal failure

  • Despite the robustness of metallic oil seals, proper installation and maintenance are crucial for optimal performance. Misalignment, over-tightening, or damage during installation can compromise the seal's effectiveness. Regular inspection and timely replacement when signs of wear are detected ensure the continued reliability of the seal.
  • NBR is recommended for the majority of standard applications and is the most commonly used rubber (elastomer) material. This is because of Nitrile's compatibility with most environments as well as its relatively low cost. Generally nitrile is used for disposable non-latex gloves, footwear, automotive transmission belts, synthetic leather, hoses, o-rings, gaskets, oil seals, and more. 

  • High- and low-temperature-resistant type
  • To serve as a physical barrier that keeps the lubricant in the designated area.
  • Stainless steel
  • In the aerospace industry, die-cut rubber gaskets are used in aircraft engines, landing gear, and hydraulic systems to withstand extreme temperatures, pressures, and vibrations. They are designed to meet stringent performance and safety standards to ensure the reliability and efficiency of aircraft systems. In the industrial and manufacturing sectors, rubber gaskets are used in pumps, valves, pipes, and machinery to prevent leakage, contamination, and wear.
  • The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.

  • You may need to turn the crankshaft so that it protrudes less. Turn the front pulley bolt with a spanner or socket.

  • Made from high-quality materials, the 5.9% Magnum valve cover gasket is designed to withstand the high temperatures and pressures inside the engine. It is engineered to provide a tight seal that prevents oil from leaking out and dirt from getting in, protecting the engine from damage and ensuring optimal performance.
  • The primary advantage of using a double oil seal is its ability to protect against both external and internal leaks. External leaks can lead to loss of lubricant,, and potential safety hazards. Internal leaks, on the other hand, can compromise the integrity of the system by allowing contaminants into the lubricant, potentially causing damage to sensitive components.
  • Begin with a thorough inspection of all involved surfaces:shaft sealing surface and housing bore, seal lip(s), and outside diameter. Maintaining the integrity of the sealing lips is “Priority 1″. The slightest tear or nick can develop into a more significant issue during operation.

  • The performance of an oil seal is crucial in ensuring the efficiency and longevity of the equipment in which it is used. A high-quality oil seal can withstand high temperatures, pressure, and speed, while maintaining a tight seal to prevent leaks. This is especially important in industries such as automotive, aerospace, and manufacturing, where even a small leak can lead to significant damage and downtime.

  • The term rubber denotes a highly elastic polymer material, which, when molded into a tube shape, offers exceptional adaptability and resistance to pressure changes. The tube in rubber tube gaskets refers to their cylindrical form, designed to fit snugly around pipes or tubes, ensuring a secure seal. Gaskets made from rubber are preferred due to their ability to withstand a wide range of temperatures, resist chemicals, and absorb shock, making them ideal for high-pressure and dynamic sealing applications.
  • In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility. 

  • Extruded silicone gaskets are manufactured by forcing molten silicone through a die, which creates a customized profile. The silicone is then cured to form a solid gasket that can be used in a variety of applications. These gaskets offer several advantages over traditional gasket materials, such as
  • However, before finalizing a purchase, it is wise to consult your vehicle's manual or a professional mechanic. They can offer advice tailored to your engine’s specifications, ensuring you get the most out of your investment. Additionally, remember that changing spark plugs is a delicate procedure that requires care to avoid damage to the threads or the plug itself.
