Oil seals come in a range of sizes ranging from 0 cm to 33 cm, and choosing the right size is critical to performance. The size of an oil seal is determined by the following dimensions:

Longer seal life can be expected with shafts having a Rockwell (RC) hardness of 30 or more. When exposed to abrasive contamination, the hardness should be increased to RC 60.
These seals are more commonly used in pumps, motors both electric & hydraulic, gearboxes & occasionally dirt wipers in hydraulic cylinders. They help protect shafts and bearings from dirt and harmful contaminants entering the internals of the application that they are fitted to, as well as prevent any leaks of lubricant.
New spark plugs are integral to the efficient operation of the engine, playing a critical role in igniting the air-fuel mixture within the combustion chambers. Over time, spark plugs can become worn or fouled, leading to decreased engine performance, rough idling, and reduced fuel efficiency. Replacing old spark plugs with new ones is essential for maintaining optimal engine performance, fuel economy, and emissions control. High-quality new spark plugs contribute to reliable ignition, smooth engine operation, and reduced environmental impact.

However, when you actually select the oil seal to use, the most important factors are past success history and points of improvement, so it is not necessary to follow this order to the letter.
