  • Truck spark plugs are essential components in the internal combustion engines of heavy-duty vehicles, playing a crucial role in the efficient operation of these machines. A spark plug's primary function is to initiate combustion by creating a spark that ignites the air-fuel mixture in the engine's cylinders. Regular inspection, maintenance, and replacement of truck spark plugs are vital to maintain optimal engine performance and extend the life of the engine.

  • 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.

  • Moreover, regular maintenance and timely replacement of oil seals are integral to machinery health. Signs of wear, such as leaks or discoloration, should prompt immediate action. Neglecting these signs could lead to severe damage, necessitating more extensive repairs or even replacement of the entire unit.
  • Types of oil seals

  • When a gasket fails, it can lead to leaks, which can result in costly clean-up efforts and potentially dangerous situations. That is why it is important to regularly inspect the gasket and replace it as needed to ensure that the oil tank remains in good working order.

  • Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.

  • An oil seal, fundamentally, is a device designed to prevent the leakage of lubricants while preventing the ingress of contaminants into the machinery. The dimensions '40x52x7' denote the size of this specific oil seal, specifying its inner diameter (40mm), outer diameter (52mm), and thickness (7mm). These measurements are crucial for proper fitment and sealing efficiency in a targeted application.

  • Wheel hub oil seals are essential components in automotive systems, serving to maintain the integrity of the wheel hub assembly. These seals are designed to prevent the leakage of lubricating oil and the entry of contaminants, safeguarding the wheel bearings and other internal components. By creating a barrier against moisture, dirt, and debris, wheel hub oil seals contribute to the smooth operation and longevity of the wheel assembly, ensuring optimal performance and safety on the road.

  • The engine, the heart of any automobile, relies heavily on gaskets. Cylinder head gaskets, for instance, sit between the engine block and cylinder head, ensuring that combustion gases don't escape and coolant and oil stay in their designated channels. They withstand extreme temperatures and pressures, making them a critical element in engine efficiency and longevity. A faulty cylinder head gasket can lead to engine failure, emphasizing the importance of this humble component.
  • When selecting a 40mm rubber gasket for a specific application, it is important to consider factors such as the operating temperature, pressure, and chemical compatibility to ensure optimal performance and longevity. Additionally, the gasket should be installed properly following manufacturer recommendations to ensure a leak-proof seal.


  • In addition to its sealing capabilities, the valve cover gasket also plays a role in regulating engine temperature. By preventing oil from mixing with coolant, the gasket helps maintain the correct temperature range for optimal engine performance.

  • Do not top up engine oil and do not start the engine until four hours after assembly. This is advised by both Elring and Victor Reinz to allow the new oil seals to form to the shaft.

  • Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.

  • What are Oil Seals and how do they work?

  • Glow plugs, the diesel equivalent of spark plugs, are designed specifically to aid in cold starts. In a diesel engine, air is compressed to a high temperature, which then ignites the fuel. However, when the engine is cold, this compression may not be enough to ignite the fuel. That's where glow plugs come into the picture. They generate heat before the engine starts, preheating the air in the combustion chamber, making it easier for the diesel fuel to ignite.

  • The oil seal is typically made of rubber or other synthetic materials that are resistant to oil and heat. It is placed in strategic locations within the motor where oil needs to be contained, such as the crankshaft and camshaft seals. These seals are essential for preventing oil leaks that can lead to engine damage and failure.
  • Overall, iridium spark plugs are a great investment for anyone looking to improve their car's performance and efficiency. With their durability, reliability, and cold starting capabilities, these spark plugs can help to ensure that your engine runs smoothly and efficiently for years to come. So, if you're looking to maximize your car's potential, consider upgrading to iridium spark plugs today.
