  • Oil seal manufacturers also play a critical role in innovation and product development. As technology advances and new materials become available, manufacturers continually strive to improve the performance and efficiency of their seals. This may involve designing seals with lower friction, higher temperature resistance, or better chemical compatibility to meet the evolving needs of their customers.

  • The spark plug is essentially a device that generates an electric spark to ignite the compressed air-fuel mixture inside the engine cylinder. This ignition process creates a small explosion, which pushes the piston down and ultimately drives the vehicle forward. Without spark plugs, the engine would not be able to start or run efficiently.


  • The valve cover gasket set is typically made of rubber or silicone material that is designed to withstand high temperatures and pressure. These gaskets are located between the engine valve cover and the cylinder head, providing a tight seal to prevent oil from leaking out. Over time, the gaskets can become worn or damaged, leading to leaks and other issues.
  • 3. Improved ignition performance The unique design of the Spark Plug 794 055A ensures superior ignition performance, providing a more consistent and powerful spark to ignite the air-fuel mixture more efficiently.
  • The primary function of the Oil Seal 20 34 7 is to prevent oil from escaping the engine's lubrication system. It acts as a barrier, stopping contaminants from entering the system while retaining the essential lubricant. A compromised oil seal can lead to oil leaks, causing engine damage, increased fuel consumption, and potentially catastrophic failure A compromised oil seal can lead to oil leaks, causing engine damage, increased fuel consumption, and potentially catastrophic failure A compromised oil seal can lead to oil leaks, causing engine damage, increased fuel consumption, and potentially catastrophic failure A compromised oil seal can lead to oil leaks, causing engine damage, increased fuel consumption, and potentially catastrophic failureoil seal 20 34 7.

  • A rear shock absorber, also known as a damping unit, is designed to dampen the oscillations and vibrations caused by road irregularities. It converts the kinetic energy from these movements into heat, which is then dissipated, preventing the car from bouncing excessively after hitting a bump. However, without an effective oil seal, the efficiency and lifespan of the shock absorber can be severely compromised.
  • The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.

  • The 'AM5C' code refers to a specific model developed by a renowned manufacturer, known for its high-quality ignition components. The 'A' typically signifies the thread size and style, while the 'M5' denotes the electrode configuration and heat range. The 'C' could represent additional features or enhancements, such as improved resistance to corrosion or enhanced ignitability under cold starts.

  • Furthermore, TC oil seals are designed to provide low friction and long service life. The smooth surface of the sealing lips minimizes wear and heat generation, ensuring efficient operation and reduced maintenance costs. With proper installation and periodic inspection, TC oil seals can last for thousands of hours without needing replacement.

  • 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

  • (5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.

  • The Versatile and Essential Thick Rubber Gasket
  • In addition to its exceptional durability, the Top Valve Cover Gasket also offers a perfect fit for a wide range of vehicle makes and models. This ensures that the gasket will provide an airtight seal, preventing oil leaks and other issues that can arise from a faulty gasket

  • Common Mistakes to Avoid

  • Choosing the right oil seal

  • Now, let's consider the pricing. Iridium spark plugs typically retail at a premium compared to standard options. Depending on the brand and application, one could expect to pay anywhere from a few dollars more per plug to potentially several times the cost of regular spark plugs. While this might seem steep at first glance, it's crucial to factor in the extended interval between replacements. If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramatic If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramatic If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramatic If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramaticiridium spark plugs price.

  • The manufacturing process typically starts with the creation of the rubber compound. This involves mixing the base rubber with additives like antioxidants, fillers, and accelerators to achieve the desired properties. The mixture is then cured or vulcanized, a process that transforms the soft dough into a strong, resilient material through heat and pressure.
