- The construction of the Oil Seal 45 62 8 typically consists of a rubber compound, often elastomeric materials like nitrile rubber or fluoroelastomer, providing flexibility and resistance to temperature extremes and chemical exposure. The seal features a primary (lip) that contacts the shaft or bore surface, creating a barrier against fluid escape The seal features a primary (lip) that contacts the shaft or bore surface, creating a barrier against fluid escape

- In modern vehicles, spark plug wires have been replaced by direct ignition systems, which eliminate the need for a distributor
- 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.

- 5. Replace the spark plug wires and ensure that they are properly connected to the distributor.
- Over time, the spark plug O-ring can wear out or become damaged due to the constant exposure to heat and pressure
spark plug o ring. It is important to regularly inspect the O-ring during routine maintenance checks and replace it if necessary. A worn or damaged O-ring can lead to oil leaks, engine misfires, and other issues that can affect the performance of the vehicle.Tap in the new seal with a wooden block, keeping it absolutely straight. - Temperature range from -30 degrees Celsius to 170 degrees Celsius
Installation
Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
Oil seals, also known as rotary shaft seals or lip seals, are a specific type of gasket designed to prevent the leakage of oil or other fluids in rotating shafts.
