- 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.
What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.


Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
An oil seal serves three crucial purposes within any machinery. First, it prevents the leakage of lubricants or fluids outside the seal, even under high pressure. This function ensures the effective operation of equipment, as sufficient lubrication is a key requirement for the smooth functioning of machinery. Second, it retains the lubricating oil within the machinery. This retention function reduces the need for constant maintenance or re-lubrication, saving time and resources. Third, the oil seal acts as a barrier against contaminants. It prevents dirt, dust, and other potential contaminants from entering the machinery, protecting sensitive parts from damage or wear.
An effective way to ensure particles do not contaminate your oil seal is to store it in a container or sealed bag away from areas where dust and debris are prevalent. Resealable, heavy-duty plastics bags and bins are ideal for keeping your shaft seal protected.

The perfect remedy for this is to use oil seal materials that are rated for the temperature of your application. Also, ensure that the elastomer is free from volatile constituents like waxes, plasticizers, etc.

Temperature - Just like pressure, the temperature that your oil seal will be operating in must be known so that you can choose one that can withstand the heat or cold. PTFE have the widest range of temperature, making them useful for machines who can see usage in extreme weather or elements.
