  • Over time, engine oil seals can become worn or damaged due to normal wear and tear or exposure to extreme temperatures and chemicals. When this happens, they may need to be replaced to prevent further damage to the engine. It is recommended to have the oil seal checked and replaced at regular intervals, typically every 30,000 to 100,000 miles, depending on the make and model of the vehicle.

  • The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.

  • The other way oil seals work is by stopping outboard materials that can damage the machine or contaminate its lubricant. The outboard materials that the oil seal will need to stop depend on the application. However, the most common kinds are dirt, moisture, and the particles produced during manufacturing.

  • Oil seals are always exposed to a lot of chemicals, both mild and harsh chemicals. The seals react by showing some signs like cracks, blisters, and discoloration especially when the chemical is harsh. This clearly shows that the chemical is not compatible with the seal, which goes as far as affecting its cross-link density (increase or decrease). When the cross-link density increases, the seal material becomes harder, but when it decreases, the seal material becomes softer.

  • Oil lip seals play a significant role in several industrial applications to avoid intermixing fluids and prevent contaminants and moisture from affecting the bearings. With such a vital role to play, it is essential to choose the right material for these seals. The choice of the material will depend on factors like the type of fluid being sealed, operating temperature, pressure, and compatibility with the operating environment. The following list of materials is typical for making oil lip seals:

  • When replacing spark plugs, it is important to follow the manufacturer's recommendations for the correct type and gap setting. Using the wrong spark plugs can lead to engine misfires and poor performance. Additionally, it is essential to properly torque the spark plugs to prevent damage to the cylinder head.


  • When the total eccentricity is excessive, the sealing edge of the seal lip cannot accommodate shaft motions and leakage may occur.
    Total eccentricity is the sum of shaft runout and the housing-bore eccentricity.
    Total eccentricity, shaft runout and housing-bore eccentricity are generally expressed in TIR (Total Indicator Reading).
