  • In recent years, the automotive industry has undergone a significant transformation, driven by technological advancements and changing consumer preferences. One such innovation is the L7TC Spark Plug, which is poised to revolutionize the way we think about engine performance and efficiency.
  • The Importance of a 4.0 Valve Cover Gasket

  • NNK is committed to the best raw materials, and uses advanced technology and equipment to solve oil seal problems for customers. Our products not only ensure the sealing effect, but also minimize the friction force. The service life is longer than the average service life of oil seals. less loss.

  • 2. Temperature: Just like pressure, it is very important to choose the right seal that can withstand extreme heat or cold temperatures, depending on the operating environment of your application.

  • Spring: spiral shaped, ensures constant pressure and maintains the optimal force to the shaft.

  • Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms

  • Another important function of the rubber carburetor gasket is to absorb vibrations
  • Polyacrylate

  • Some aspects to consider when selecting this component are:

  • The best seal performance is achieved when close shaft and bore tolerances are present. Other factors include shaft eccentricity, end play and vibration.

  • Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.


  • A spark plug valve cover gasket is a thin, usually rubber or silicone-based, seal that sits between the engine's valve cover and the cylinder head. Its primary function is to prevent oil leaks from occurring around the spark plugs, ensuring that oil stays where it's needed - in the engine, not in the combustion chamber. Oil leakage into the combustion chamber can lead to a phenomenon known as oil burning, which can result in decreased fuel efficiency, excessive smoke, and potentially, engine damage.

  • Obtaining adequate adhesion of fluoroelastomer compounds to metal inserts is a major consideration in fabrication of shaft seals. Adhesive systems worked out for bisphenol-cured VDF/HFP/TFE elastomers often do not perform adequately for peroxide-curable fluoroelastomers and more base-resistant polymers that contain little or no VDF. The trend toward use of more resistant fluoroelastomers in shaft seals has necessitated considerable effort on compounding and adhesive system development to get adequate bonding of the new materials. Silane-type primers are often used to coat metal inserts; these contain residual active groups such as amine functions that interact with the fluoroelastomer compound to attain good adhesion, especially for VDF/HFP/TFE elastomers. Other adhesive systems, using epoxy compounds or tie-coats, may be necessary for difficult bonding situations.3
