Oil seals come in a vast range of materials and compounds. Even older materials, such leather, are still used today. Nitrile is among the most common materials for oil seals but is slowly losing ground to PTFE, which is gaining popularity due to its effectiveness in high-speed applications.

3. Shaft and housing design
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.
