- In conclusion, the price of a shock absorber oil seal is not just about the upfront cost but also the value it brings to your vehicle's performance and safety. Investing in a reliable and durable oil seal, along with professional installation, is a wise decision for any car owner. Remember, prevention is always better than cure, and a well-maintained oil seal is a key component in keeping your vehicle running smoothly and safely.
Prepare the shaft and prevent damage
The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.
An outer case, a body made of metal or provided with a rubber layer
- The interplay between these two components is critical. A faulty valve cover gasket can lead to oil contamination on spark plugs, causing them to malfunction. Conversely, worn spark plugs can lead to increased oil consumption due to uncontrolled combustion. Hence, the synergy between a well-sealed valve cover and efficiently firing spark plugs is pivotal for a smoothly running engine.
- It is chlorinated and aromatic hydrocarbon resistant.
Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
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.
-20~180 - The manufacturing process involves several steps, including molding, shaping, coating, and testing. The electrodes are shaped and calibrated to exact measurements, while the insulator is coated with a ceramic material to provide insulation and durability. The housing is also carefully crafted to withstand the high temperatures and pressures within the engine cylinder.

Choosing Quality Industrial Oil Seals
By far, nitrile is the most popularly used, but buyers who need seals for applications involving high-speed shaft rotation increased interest. Viton is another alternative for silicone and poly-acrylic because it’s more resistant to harmful chemicals and abrasion and works better in higher temperatures.
2. Use the correct lubricant

First disconnect the battery earth terminal , to avoid the risk of a short circuit while the fuel pipes are disconnected.

(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
