4. Fluroelastomer also popularly known as Viton. – The high temperature resistant material used in places where temperature is more than 120 Degree Celcius.



Type C Oil seal
Another common cause of black spark plugs is engine oil leakage. If oil is leaking into the combustion chamber, it can cause the spark plugs to become fouled with a black, sooty residue. This can lead to misfires and engine hesitation, as well as increased fuel consumption. It is important to address any oil leaks promptly and replace the spark plugs if necessary.
However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
Description:
FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.
Begin with a thorough inspection of all involved surfaces:shaft sealing surface and housing bore, seal lip(s), and outside diameter. Maintaining the integrity of the sealing lips is “Priority 1″. The slightest tear or nick can develop into a more significant issue during operation.
Overview of Oil Lip Seals
Oil seals are used in a great many devices for steel production equipment.
Figure 7 shows the places where each seal type is used in a rolling mill.

794 00055a spark plug. Over time, spark plugs can become fouled with carbon deposits, which can decrease their effectiveness. The 794 00055A spark plug is designed to resist fouling, ensuring that it will continue to provide a consistent spark for optimal engine performance.
