- But what truly sets Double Platinum Spark Plugs apart is their ability to withstand extreme temperatures. The high-quality materials used in their construction allow them to maintain stability even at temperatures exceeding 1400 degrees Celsius. This is crucial in modern engines, which operate at higher temperatures due to increased compression ratios and advanced turbocharging systems.
Ultimately, oil seals are devices that help to exclude dust and dirt, etc., while at all times retaining the lubricant in the piece of equipment.
Set the gasket on the block and make sure that all holes are perfectly aligned before refitting the head (See How to remove a cylinder head ).
NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.
