- Regular maintenance is essential for the proper functioning of truck spark plugs. This includes inspecting the plugs regularly for signs of wear or damage, such as chipping or corrosion. If damage is detected, the spark plugs should be replaced immediately to prevent further engine damage. Additionally, the engine's compression should be checked regularly to ensure that the spark plugs are operating under the correct conditions.



As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.

To act as a barrier and prevent dirt, contamination and other external entities from entering the system containing the lubricating oil.
(2) When the ambient temperature is high, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be selected. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.
The most common and economical material within the sealing industry, Nitrile, is used in many oil applications, the automotive sector for aircraft fuel applications, military and marine applications, and more.
