In general, oil seals should be selected in the order of priority indicated in Table 1.
A
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.
There are different types of spark plugs available, including copper, platinum, and iridium. Each type has its own advantages and disadvantages, so it is important to choose the right spark plug for your vehicle based on its specific needs.
Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.
Lastly, sustainability is a growing concern in the automotive sector. A responsible spark plug supplier should be committed to eco-friendly practices, from manufacturing processes to disposal methods, minimizing environmental impact.made of a yieldable resilient material having flat sealing faces and comprising two ring portions connected together by an annular portion substantially v-shaped in cross-section which may yield or expand as the mounting requires.The function of the rear shock absorber is to dampen the oscillations caused by uneven road surfaces, thereby reducing the bouncing motion of the car's body. At its heart, the oil seal acts as a barrier, separating the pressurized oil from the external environment. This seal, if damaged, can lead to oil seepage, which not only impairs the shock absorber's performance but also poses potential damage to other vehicle components due to lubrication loss.

Overall, PTFE oil seals are a reliable and durable sealing solution for a wide range of industrial applications. Their superior chemical resistance, low friction properties, and ability to withstand harsh operating conditions make them a popular choice for engineers and maintenance professionals looking to improve the performance and reliability of their equipment. Whether you are in the automotive, aerospace, or manufacturing industry, PTFE oil seals are an excellent choice for sealing applications where efficiency and longevity are important.
Seals perform best when they are lubricated, however, some machines quickly go on dry spells. So, in cases like this, choosing a leather or PTFE seal is the right decision to make as both of them can function with less lubrication than other types of seals.
