  • Installation and maintenance of the Oil Seal 20 34 7 require precision and expertise. Incorrect installation can lead to premature failure, necessitating frequent replacements and increasing maintenance costs. Regular inspections and timely replacement of worn-out seals are essential for avoiding potential issues.
  • Oil seals, also known as grease seals or shaft seals, are essential components in many machines and systems. They play a crucial role in preventing the leakage of oil and other lubricants, ensuring the smooth and efficient operation of various mechanical parts.


  • No contact
  • In addition to their electrical properties, marine spark plug wires must also be flexible and durable enough to withstand the constant vibrations and movements experienced by boats
  • Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment. This does not apply to silicone rubber seals and seals with hydrodynamic features, other than WAVE lip designs. also recommends using a hydraulic press, with suitable tools, to install a seal in its housing bore. Pressure should be applied as close as possible to the outside diameter of the seal.”  Oil seals are commonly used in a variety of industries. Below are 5 types of oil seals used in today’s manufacturing and machinery industry.

  • Why use NOK-CN factory-made oil seals?

  • Cylinder head gaskets are a vital component of a vehicle's engine, playing a crucial role in maintaining the integrity of the combustion chamber. These gaskets are designed to seal the gap between the engine block and cylinder head, preventing any fluids or gases from escaping or leaking into the combustion chamber.
  • Silicone

  • Moreover, the adaptability of NBR oil seals caters to the diverse demands of industry
  • Regular inspection and maintenance of spark plugs are essential to identify signs of wear, fouling, or deterioration. Proper replacement of worn or fouled spark plugs, including the transition to iridium spark plugs where applicable, is crucial for maintaining the efficiency and reliability of the vehicle's ignition system. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's engine.

  • The 'gasket' part of the term refers to the shape and function, typically circular or annular, designed to conform to the contours of the mating surfaces. The 'seal', on the other hand, highlights its purpose - to provide a barrier against fluids, gases, or particles that could potentially cause damage or compromise system performance.
  • In addition to improving engine performance, replacing the Myvi valve cover gasket can also help to prevent future problems with the engine. By ensuring that the engine is properly sealed, you can reduce the risk of oil leaks and other issues that can cause further damage to the engine over time.
  • In conclusion, there are several different types of spark plugs available, each with its own advantages and disadvantages. Choosing the right spark plug for your vehicle can improve performance, fuel efficiency, and overall engine health. Whether you drive a daily commuter car or a high-performance sports car, selecting the right spark plug is essential for optimal engine performance.
  • Molded gaskets are versatile, durable, and cost-effective sealing solutions that are widely used in various industries. By understanding the different types of molded gaskets, their materials, manufacturing processes, applications, and maintenance requirements, you can choose the right gasket for your specific needs and ensure optimal performance and longevity.
