  • The maximum allowable shaft speed is a function of the shaft finish, runout, housing bore and shaft concentricity, type of fluid being sealed and the type of oil seal material.

  • 9 Factors for Selecting Oil Seals

  • The inclusion of 7% steel, often in the form of a metallic insert or spring, further fortifies the oil seal's performance
  • Nitrile rubber (NBR)

  • ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).

  • The DT466 valve cover gasket is a crucial component in maintaining the optimal performance of your engine. This gasket plays a vital role in sealing the valve cover to the engine block, preventing oil leaks and ensuring that the engine runs smoothly.
  • Begin with a thorough inspection of all involved surfaces:shaft sealing surface and housing bore, seal lip(s), and outside diameter. Maintaining the integrity of the sealing lips is “Priority 1″. The slightest tear or nick can develop into a more significant issue during operation.

  • Moreover, a reliable supplier ensures consistent quality through rigorous testing and quality control processes
  • It can withstand exposure to ozone, air, and sun 
  • Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.  

  • Improper installation can cause your oil seal to malfunction. While being tapped into place, it can become tilted or misaligned in the bore. That being said, setting it up correctly will help ensure that the sealing process is effective.

  • Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of synthetic and conventional base oils, plus some additives, for extra resistance to oxidation and excellent low-temperature properties. Synthetic blends make it easy for drivers to make the switch from conventional to synthetic oil, which is why this type of oil is becoming increasingly popular among today’s savviest drivers. It’s also a great middle ground for drivers who want the added protection and performance of a synthetic oil, but might not be ready to foot the bill for a total switch to full synthetic oil.

  • Slacken the alternator or dynamo adjuster and pivot bolts, push the unit inwards and ease off the drive belt. Remove the belt completely.

  • The numbers 30-50-10 indicate the dimensions of the oil seal, specifically its inner diameter, outer diameter, and height. This measurement ensures that the oil seal fits perfectly into the designated space and effectively seals off any potential leaks.


  • Metal-to-oil seals are essential components in a wide range of applications, including automotive, industrial, and aerospace sectors. These seals play a crucial role in maintaining the integrity of fluids within systems by preventing leaks and contamination. In this article, we will delve into the basics of metal-to-oil seals, their types, materials, and applications, as well as maintenance and troubleshooting tips.

  • In the intricate symphony of an engine's operation, every component plays a pivotal role. Among these components, the top valve cover gasket might seem inconspicuous, yet its significance is paramount. This article delves into the importance of maintaining and replacing this often-overlooked part to ensure the smooth running of your engine.
  • a. Carbon Steel – the most common material used in oil seals.
  • Another benefit of neoprene rubber gaskets is their excellent chemical resistance. They can effectively seal against a wide variety of chemicals and fluids, including acids, alkalis, and hydrocarbons. This makes them an ideal choice for applications in the chemical processing, automotive, and marine industries, where exposure to corrosive substances is common.
  • Another important feature of silicone rubber gaskets is their flexibilitysilicone rubber gasket. They can be easily deformed to fit various shapes and sizes of joints, making them suitable for use in a wide range of applications. This flexibility also allows them to compensate for minor misalignment or movement in joints, ensuring a tight seal.
  • Features of the Spark Plug 794 055A
  • The 7% that often goes unnoticed in the composition of an oil seal is a critical component—the sealing element. This could be a specialized grease or coating that ensures the seal conforms properly to the mating surfaces, preventing leak paths. Without this 7%, the effectiveness of the oil seal is compromised, leading to potential contamination of the lubricant and subsequent damage to the machinery.
  • A spark plug ignition coil plays a crucial role in the functioning of an internal combustion engine. It is responsible for generating the high voltage needed to create a spark within the combustion chamber, igniting the air-fuel mixture and initiating the power stroke. Without a properly functioning ignition coil, the engine would not be able to start or run efficiently.


  • Oil seals, also known as shaft seals or lip seals, are critical components in a wide range of industries, including automotive, aerospace, mining, and construction. They prevent the loss of lubricants, protect against ingress of dust and other contaminants, and maintain the integrity of hydraulic and pneumatic systems. The quality and reliability of these seals are paramount, making the choice of supplier a crucial decision for any business.
  • Furthermore, the use of rubber offers chemical and weather resistance advantages

  • Moreover, a compromised valve cover gasket can allow debris and moisture to enter the engine, leading to corrosion or even engine failure in extreme cases
  • One of the key advantages of the 22x35x7 oil seal is its ability to withstand high pressures without leaking. Whether you're working with hydraulic systems, transmissions, or other high-pressure applications, this seal can maintain its integrity and prevent costly leaks that can lead to downtime and maintenance expenses. Its self-lubricating properties also reduce friction, increasing the efficiency of the system and extending the life of the seal itself.
