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.
- The superiority of NBR as a sealing material stems from its molecular structure, which combines the durability of butadiene with the chemical resistance of acrylonitrile. This blend creates a resilient elastomer that can operate effectively in applications spanning from automotive engines to hydraulic systems in heavy machinery. Its elastic properties ensure a tight fit, preventing leaks and prolonging the lifespan of machinery by minimizing maintenance requirements.


When selecting spark plugs for motor vehicles, it is important to consider the specific requirements of the vehicle, including heat range, electrode design, and material composition. Iridium spark plugs are known for their fine-wire electrode and superior durability, making them suitable for a wide range of motor vehicle applications. The use of high-quality iridium spark plugs can contribute to optimized engine performance, fuel efficiency, and emissions control, ensuring reliable operation and reduced environmental impact.
Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms


Oil seals in any size, material or quantity
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.
