Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
- Testing procedures are also outlined in the oil seal standard to ensure consistent quality across different manufacturers. Testing may include procedures such as leak testing, pressure testing, and endurance testing to ensure that the seal can perform as expected under real-world conditions.

- Regular maintenance of the rear shock absorber oil seal is essential to ensure the proper functioning of the suspension system and the safety of the vehicle. By keeping an eye on the condition of the seal and promptly replacing it when necessary, drivers can enjoy a smooth and comfortable ride, as well as peace of mind knowing that their vehicle is in good working order.
Oil seals in the motor, including the engine and other critical components, are essential for maintaining the integrity and efficiency of the vehicle. These seals are designed to contain lubricating oil and prevent leaks, contributing to the smooth operation and longevity of the motor. Proper maintenance and replacement of oil seals in the motor are crucial for the reliability and performance of the vehicle's systems.

Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
