NBR Rubber Washers Seals material offers relatively low cost, good mechanical properties, and resistance to many common oils, fuels, and lubricants. NBR has poor resistance to weathering, sunlight, and ozone so it is best used in enclosed environments where parts are not exposed to the elements. Hydrogenated versions of NBR (HNBR) have enhanced mechanical properties as well as greater thermal and chemical stability.

Benefits of NBR Rubber Washers Seals
- Oil resistance: NBR seals are particularly well known for their strong resistance to petroleum products, making them ideal for applications involving oils and fuels.
- Tear resistance: The material has good tear strength, which can extend the life of seals in dynamic applications.
- Versatility: NBR rubber can be formulated with different levels of acrylonitrile, allowing it to be tailored to specific resistance needs (for example, higher acrylonitrile content increases oil resistance but reduces flexibility).
Application
1. Automotive Industry:
Used in fuel systems, engines, fuel tanks, and various parts that require oil resistance.
2. Hydraulic Systems:
Commonly used in hydraulic seals due to its ability to withstand high pressures and contact with hydraulic oil.
3. General Industrial Uses:
Used in machinery and equipment that frequently come into contact with oil or grease.
4. Pumping and Piping Systems:
Seals for pumps and pipes that handle liquids, including hot and cold water.
5. Food Processing:
Certain grades of NBR are suitable for food contact applications, so they can be used in food processing equipment.
6. Aerospace and Military:
Valued for its durability and resistance to harsh environments.
7. Telecommunications:
Used in cable sheathing and other parts that require weather resistance.
In addition to specific applications in auto parts, this material can be used to make seals of corresponding sizes in other fields, such as military industry, aviation, and electronics. If you need further sealing solutions, please contact our factory.
