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.
The sealing element makes up the interior of the oil seal, and the materials commonly used are:
The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
- When it comes to engine performance, a faulty center bolt valve cover gasket can have a detrimental effect. Oil leaks not only result in a loss of lubrication, which can cause excessive wear and tear on engine components, but they can also lead to a buildup of sludge and contaminants within the engine. This can ultimately result in reduced engine efficiency, increased fuel consumption, and a shortened service life This can ultimately result in reduced engine efficiency, increased fuel consumption, and a shortened service life

- Nitrile (NBR): The nitrile rubber or nitrile provides excellent resistance to numerous oils and greases, including mineral grease and hydraulic oil. There are several synthetic lubricants and greases in the market based on glycol which may cause harm to NBR rubber compounds depending on their composition. Due to their excellent durability and cost-effectiveness, these seals are used in a wide range of operating conditions. However, NBR is unable to withstand exposure to acids and solvents.
- Aircraft spark plugs are specially designed to withstand the harsh conditions and high temperatures encountered in the engine compartment of an aircraft. They are made of durable materials such as nickel alloy, platinum, or iridium that can withstand extreme heat and pressure. This durability is essential for ensuring the reliable operation of the aircraft engine during flight.
- In addition to preventing oil leakage, oil seals also protect the internal components of machinery from contamination by dust, dirt, and other harmful particles. This helps to extend the lifespan of the equipment and reduce the need for costly repairs and maintenance

- The performance of a vehicle significantly depends on the health of its spark plugs. Worn or dirty spark plugs can lead to reduced fuel efficiency, engine misfires, rough idling, and even complete engine failure. Therefore, regular maintenance, including checking and replacing spark plugs as needed, is crucial for optimal car performance.
- The primary function of a radial oil seal is to maintain the integrity of the lubrication system within the machinery. By preventing the loss of oil, these seals help to ensure that the moving parts remain properly lubricated, reducing friction and wear, and extending the life of the equipment. In addition, by containing the oil within the system, radial oil seals help to prevent contamination of other components and systems, ensuring optimal performance and reliability.

In addition to these standardised types, the following special types are also available:
In general, oil seals should be selected in the order of priority indicated in Table 1.

The durometer of an oil seal is typically dependent on the material it is made with. Common oil seal materials along with their durometers are as follows:
2. Silicone – Used in specific applications where only light loads are applied.


Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
Regular maintenance and inspection of shaft oil seals are essential to ensure their proper functioning and prevent costly downtime and repairs. Signs of a worn or damaged seal include oil leaks, increased noise or vibration, and decreased efficiency. If any of these symptoms are detected, it is important to replace the seal promptly to avoid further damage to the machinery.
A faulty spark plug ignition coil can cause a variety of problems with engine performance. Symptoms of a failing ignition coil may include misfires, rough idle, hesitation during acceleration, and reduced fuel efficiency. If left unchecked, a faulty ignition coil can eventually lead to engine stalling or complete failure to start.
