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.
- Thick rubber gaskets find their application in numerous industries, including automotive, plumbing, aerospace, food processing, and chemical engineering. In automotive engines, they prevent oil and coolant leaks, ensuring optimal performance.

The design of high-pressure oil seals is also critical to their performance. The seals must be able to maintain a tight fit between the moving parts, while also allowing for some flexibility to accommodate minor variations in the shaft or housing. This balance between rigidity and flexibility is essential for ensuring a reliable seal under high pressure conditions.

Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions.
Figure 9 shows items relating to oil seal characteristics.
Regular inspection and maintenance of rubber valve cover gaskets are essential to identify signs of wear, damage, or leakage. Proper replacement of worn or damaged gaskets is crucial for maintaining the integrity and performance of the engine. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's engine.
