A standard oil seal consists of an outer circular metal disk with an inner flexible rubber which is affixed to the metal during vulcanization. The bonded seal has no loose parts to allow leakage of oil or ingress of any contaminants. This kind of seal is more accurate, and can easily be fitted into a smaller space. An example is shown in Figure 2.9.
Generally, an oil seal is made up of an outer circular metal part and a bonded inner flexible material (often nitrile rubber) that does the actual sealing.
The material used in oil seals is also important, as it affects the seal's durability and resistance to chemicals and heatMost oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.
Finally, consider the size and shape of the gasket, as well as any specific design requirements that may impact the gasket's performance. Custom-made natural rubber gaskets can be designed to meet the unique needs of your application, ensuring a precise fit and optimal sealing performance.
There are different types of spark plugs available on the market, each designed for specific engine types and operating conditions. The most common types are copper, platinum, and iridium spark plugs. Copper spark plugs are the most affordable and provide good performance for everyday driving. Platinum spark plugs offer better longevity and performance, while iridium spark plugs are the most durable and provide the best spark performance.
