  • The top valve cover gasket serves as a protective barrier between the valve cover and the engine's cylinder head. Its primary function is to seal the area around the valves, preventing oil from leaking out and keeping contaminants from entering the engine. A failure in this small but mighty gasket can lead to a myriad of problems, including oil leaks that not only damage other engine parts but also pose environmental concerns.
  • Moreover, a faulty valve cover gasket can also cause oil to mix with coolant, leading to a condition known as mayonnaise in the coolant, which is a clear indication of a problem

  • Coat the sump flange with gasket-sealant and fit the flat parts of the gasket to it, ensuring that they are exactly positioned and joined.

  • The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.

  • Imperfections on the shaft (burr, corrosion, etc.), which will directly affect the service life of the oil seal.

  • Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.

  • The sealing lip of PTFE oil seals is protected by a plastic sleeve, which can normally be used as a mounting aid. Therefore, the sleeve should remain in place until the seal is installed.

  • One of the key advantages of neoprene rubber gaskets is their exceptional durability. They can withstand extreme temperatures, both hot and cold, without losing their shape or integrity. This makes them suitable for use in environments where other types of gaskets may fail or degrade over time. Additionally, neoprene rubber gaskets are highly resistant to ozone and UV radiation, ensuring that they maintain their performance even when exposed to harsh environmental conditions.

  • The wheel and oil seal are two integral components of an automobile's engine that work together seamlessly to ensure the smooth functioning of the vehicle. The wheel is the outer part of the tire that allows the vehicle to move, while the oil seal acts as a barrier between the moving parts of the engine and the external environment, preventing oil leaks and ensuring the longevity of the engine.
  • Despite their small size, the performance of spark plugs can significantly impact engine efficiency, power output, and overall vehicle health. Fouled or worn spark plugs can lead to a litany of issues, including reduced gas mileage, increased emissions, engine surging, and difficulty starting. In severe cases, misfiring spark plugs can cause engine damage due to unburnt fuel traveling through the exhaust system, leading to overheating and potential catalytic converter failure.
  • In addition to preventing oil leaks, oil seals also help to keep contaminants out of the motor. Dust, dirt, and debris can cause damage to the internal components of the motor if they are allowed to enter. The oil seal acts as a barrier to keep these harmful substances out and maintain the cleanliness of the motor.

  • There are a wide variety of industrial applications and therefore there are a wide variety of oil seals to meet the specific application needs.  By choosing the right oil seal you will have a better fit, improved stability, and enhanced reliability.  Rubber tends to be one of the most commonly used oil seal materials. an oil seal manufacturer, explains how oil seals for and the importance of proper installation, “To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. The shaft counterface surface and housing bore should meet the demands specified in the sections Shaft requirements and Housing bore requirements. To facilitate seal installation and to achieve initial lubrication, prior to installation, recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.

  • It is important to use the correct gasket for your specific oil tank to ensure a proper fit and seal. There are many different types of gaskets available, so be sure to consult with a professional if you are unsure which one to use.

  • An effective way to ensure particles do not contaminate your oil seal is to store it in a container or sealed bag away from areas where dust and debris are prevalent. Resealable, heavy-duty plastics bags and bins are ideal for keeping your shaft seal protected.

  • VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.

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

  • High-pressure oil seals, as the name suggests, are designed to withstand pressures far beyond the standard range. They are engineered with superior materials and advanced designs to handle pressures reaching several thousand bar, making them essential in industries such as automotive, aerospace, mining, and petrochemicals where high-pressure applications are commonplace.

  • Silicone rubber gaskets are a highly versatile material that has found widespread application in various industries due to their exceptional properties. These gaskets are made from silicone, a synthetic polymer known for its durability, heat resistance, and chemical resistance. This makes them an ideal choice for sealing applications where extreme conditions are present.
