  • The main lip is the most critical component of the seal.
    Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
    (See Figure 3.)
  • The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.

  • Peroxide

  • Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.

  • Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.

  • Remove the key and keep it safe until ready to refit the pulley.

  • Over time, the oil seal can become worn or damaged due to exposure to extreme temperatures, UV rays, and road debris

  • Oil seals, often made from high-quality rubber compounds or synthetic materials, are designed to prevent the leakage of lubricants while inhibiting the ingress of contaminants. The 8 in the name likely refers to the percentage of oil-resistant material used in the seal's construction, enhancing its ability to withstand exposure to various oils and lubricants without degradation.
  • Replacing a power steering oil seal is a relatively straightforward process for a trained technicianpowerpower steering oil seal. The old seal is removed from the power steering pump, and a new seal is installed in its place. It is important to use a high-quality replacement seal to ensure that the power steering system functions properly and that leaks are prevented.
  • In recent years, advancements in spark plug technology have led to the development of 'ignition spark plugs' with improved durability and energy efficiency. These modern plugs, often featuring precious metals like iridium or platinum, boast longer life spans and better resistance to wear, further enhancing engine performance.

  • 8 Tips to Keep in Mind when Installing or Replacing Oil Seals

  • Polyacrylate (ACM) Oil Seals

  • Oil seals are an essential component of many industrial machines and equipment. They play a crucial role in preventing oil leaks, protecting bearings and other crucial parts from contamination, and ensuring the overall smooth operation of the machinery. One popular and widely-used size of oil seal is the 75x100x10 model.


  • Iridium spark plugs are the most advanced and expensive type of spark plug. They offer the best performance and longevity, with some models capable of lasting up to 100,000 miles. Iridium spark plugs have a very small electrode, which allows for a more precise spark and improved engine performance. They are recommended for high-performance vehicles and those with turbocharged engines

  • 5. Curing After molding, the gasket is allowed to cure at room temperature or under controlled conditions to ensure proper bonding and stability.
  • Over time, the oil seal can become worn or damaged due to exposure to extreme temperatures, UV rays, and road debris

  • Surface Stop Installation

  • Refit the distributor, ensuring that the rotor arm is exactly in line with the first mark. If not, withdraw the distributor and try again.

  • Polyacrylate (PA) Oil Seal: 75 durometer (+/- 5)
  • It is ozone, weather, and sun resistant 

  • There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.

  • Both the PTFE sealing lip and the shaft surface must be completely dry. Do not use grease or oil. If grease or oil is used, the retaining ring will fail after assembly. 

  • Oil seals are used in many areas around the car.
