- wear resistance and high friction coefficient, fluorosilicone rubber is only recommended for static seals.
- Silicone gasket sheets also provide excellent electrical insulation. They have a low dielectric constant and high dielectric strength, which make them suitable for use in electrical applications where insulation is critical. This,。
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.

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.
This represents a new generation of oil seals.
Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.
O-rings are one of the items used to prevent leaks and product failures. Due to their cogent functions, it’s important that they are installed appropriately without causing any damage in the process.
Maintenance and Replacement
Several prominent companies specialize in the manufacturing of oil seals, offering a wide range of sealing solutions for industrial and automotive applications. These companies leverage advanced manufacturing capabilities, extensive research and development, and a deep understanding of industry-specific requirements to produce high-quality oil seals. Leading companies in the oil seal manufacturing sector are known for their commitment to innovation, quality, and customer satisfaction, providing reliable sealing solutions for critical components in machinery and vehicles.
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.
