  • 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

  • An oil seal type that is resistant to oils, fuels, and solvents, fluorosilicone also offers temperature stability.  Primarily found in aerospace fuel applications and automotive fuel emission control, this o ring material is fast becoming popular in more and more oil-based applications across a wide spectrum of industries.

  • Lastly, the 7% signifies the recommended maximum allowable radial deflection for an oil seal35 47 7 oil seal. This parameter is vital because it determines the seal's ability to withstand pressure and maintain its integrity. Exceeding this limit can lead to deformation, compromising the seal's sealing capacity and potentially causing leaks. Engineers must consider factors such as operating pressure, temperature, and shaft eccentricity to ensure the seal remains within this tolerance.

  • What Is an Oil Seal?

  • - Clean the valve cover and cylinder head threads to ensure a good seal when installing the new gasket.
  • All rubber or polymers
  • Regular inspection and maintenance of oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of oil seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the equipment.

  • Oil tank gaskets are typically made from a durable material such as rubber or cork, which is designed to withstand the high temperatures and pressures that are common in oil tank systems. These gaskets are placed between the tank and the various components of the system, such as the fuel line and the oil filter, to create a tight seal that prevents oil from escaping.
  • When it comes to maintaining the performance of your vehicle, one of the most important components to consider is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in your engine's combustion chamber, which in turn powers your vehicle. Among the various brands and types of spark plugs available in the market, Mico spark plugs are known for their quality and reliability.


  • Neoprene rubber gaskets are also known for their excellent mechanical properties
  • Double Lips
  • Replacing the fuel-pump gasket

  • Proper installation of the 25x47x7 oil seal is essential to ensure its effectiveness. It is important to carefully clean and prepare the surfaces where the seal will be placed, as any dirt or debris can compromise the seal's ability to function properly. Additionally, the seal should be installed with the correct orientation and pressure to create a tight and secure seal.

  • In the realm of high-performance vehicles and racing applications, double iridium spark plugs have become indispensable. Their superior igniting power enables faster engine starts, quicker acceleration, and optimized power output, making them a favorite among enthusiasts and professionals alike.
  • In the intricate world of automotive engineering, the oil seal, a seemingly minor component, plays a pivotal role in ensuring the longevity and optimal performance of a vehicle's engine. A prime example is the Oil Seal 20x35x7, a specific type of oil seal that is designed to meet stringent requirements for sealing oil and other lubricants in various mechanical applications.
  • Oil seals are made out of nitrile synthetic rubber with steel stiffener rings. Other rubbers such as viton, silicon, neoprene or poly acrylic can be used for specific applications. The stiffener rings may be stainless steel or brass where highly corrosive fluids are to be sealed. Springs are generally made of spring steel to IS: 4454:Gr.ll or from stainless steel or bronze for corrosion resistance

  • To prevent thelubricating oil from leaking outside even under high pressure of the oil.

  • In conclusion, oil seal dimensions play a critical role in the efficient operation of mechanical systems. By understanding the importance of oil seal dimensions, their common types, and how to measure them, you can ensure the proper selection, installation, and maintenance of oil seals, maintaining the reliability and efficiency of your mechanical systems.
