Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
Oil seals normally consist of three basic components: the sealing element, the metal case, and garter spring.
Most conventional oil seals are designed only to withstand very low-pressure applications (about 8 psi or less). If additional internal pressure is present or anticipated, pressure relief is necessary.

An ignition spark plug is a crucial component in the internal combustion engine of a vehicle. It plays a key role in starting the engine and ensuring it runs smoothly. Without a functioning spark plug, the engine would not be able to ignite the air-fuel mixture, resulting in the vehicle being unable to start.
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Lubricant Amount - Seals will always perform best when lubricated, however in some machines there are more likely to be dry spells. For these cases, selecting a leather or PTFE seal will be beneficial, as both can operate with less lubrication than others.

Oil seals come with various lip designs, each serving a unique purpose and suitable for different applications. Let’s discuss the most common industry-standard lip designs:

With a helper holding the engine steady, remove the wedge supports, lower the engine and reconnect the mountings loosely.
Significance of Valve Cover Gaskets and Head Gaskets

hard rubber gasket. They can be compressed between two surfaces without losing their sealing properties, ensuring a leak-free connection. This feature is crucial in applications where a consistent and reliable seal is critical for the proper functioning of equipment.
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.

spark plug o ring. It is important to regularly inspect the O-ring during routine maintenance checks and replace it if necessary. A worn or damaged O-ring can lead to oil leaks, engine misfires, and other issues that can affect the performance of the vehicle.
