- In addition to preventing oil leaks, the C15 valve cover gasket also plays a role in maintaining the engine's performance. A faulty gasket can cause a loss of compression, which can reduce the engine's power and efficiency. This is because the gasket helps to create a tight seal between the valve cover and the engine block, which is essential for maintaining the correct pressure within the engine.

- One of the key advantages of TC oil seals is their ability to withstand high pressures and temperatures. This makes them suitable for a wide range of applications, including automotive engines, industrial machinery, and hydraulic systems. Whether it's sealing oil in a gearbox or hydraulic cylinder, TC oil seals offer reliable performance and long-lasting durability.
- Polytetrafluoroethylene (PTFE): This fluoropolymer is known by the brand name Teflon and is known to assure the best chemical resistance and exceptionally little frictional resistance. It is the material of choice for several types of rotating seals used in the chemical, food, and pharmaceutical industries.

In this article, we’ve discussed everything you need to know about oil seals, which are sometimes called radial shaft seals. Also, we’ve discussed the various types, their installation, and how to choose the right one for your application. With all these, you will be able to make an informed decision about the best oil seal for your needs.


Free the cover by levering gently round the edge with a screwdriver; take care not to bend the flange.

■Dispersants: This is your oil’s magic ingredient. It gives your oil the ability to absorb and hold solid contaminants so that they don’t damage the engine.
Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.

Another factor that can affect the cost of new spark plugs is the brand. Some well-known brands in the automotive industry may charge a premium for their spark plugs due to their reputation for quality and reliability. However, there are also more affordable brands that offer reliable performance at a lower cost.

When the engine is running, the ignition coil receives a signal from the engine control unit to fire at the correct time. The coil then rapidly builds up a magnetic field within the primary winding when the signal is received, and when the signal is cut off, the magnetic field collapses rapidly, inducing a high voltage in the secondary winding. This high voltage is then sent to the spark plug, where it jumps the electrode gap, igniting the air-fuel mixture in the combustion chamber.
NBR is recommended for the majority of standard applications and is the most commonly used rubber (elastomer) material. This is because of Nitrile's compatibility with most environments as well as its relatively low cost. Generally nitrile is used for disposable non-latex gloves, footwear, automotive transmission belts, synthetic leather, hoses, o-rings, gaskets, oil seals, and more.
