It is important for the spark plug to produce a strong and consistent spark in order for the combustion process to be efficient. Over time, the spark plug can become worn or dirty, which can affect its performance. This is why it is recommended to regularly inspect and replace spark plugs as needed to ensure optimal engine performance.
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 SEAL
How does an Oil Seal Work
Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
Silicone rubber (VMQ)
Oil seals are called rotary shaft seal or radial lip also.
Outer case

What are Oil Seals and how should they be ordered?
The main benefits of Nitrile when opting for use as an oil seal includes:


There are several materials used to manufacture oil seals. They are discussed below.
There are various sizes of industrial and ordinary oil seals, ranging from 0 to 33cm (13in). These varieties are also designed for different temperatures. As long as your seal matches the original equipment it’s intended for, you can be sure your machine will perform at its best.
