NBR, or nitrile butadiene rubber, is a synthetic rubber material renowned for its resistance to oil, fuel, and other chemicals. This makes NBR O Rings particularly suitable for applications where exposure to these substances is common. The material also boasts durability and flexibility, making it a preferred choice in a variety of sealing solutions.
Choosing the correct size of an NBR O Ring is critical for sealing effectiveness. O Rings are typically measured by their inner diameter (ID) and cross-section diameter (CS). To select the right size, measure the groove where the O Ring will sit, ensuring to account for the ID and CS. If you are unsure, consult an O Ring size chart or a professional for guidance.
NBR O Rings are widely utilized in applications where oil and fuel exposure is frequent, such as in automotive engines, hydraulic systems, and industrial machinery. They are also suitable for food-grade applications, provided they meet the relevant standards. When selecting NBR O Rings, it's essential to consider the operational environment and the substances they will be in contact with.
NBR O Rings have temperature resistance properties typically ranging from -30°C to 100°C (-22°F to 212°F), depending on the specific formulation. Exposure to higher temperatures can lead to degradation and loss of sealing effectiveness. For high-temperature applications, consider alternative materials like silicone or fluorocarbon which may offer better performance.

Proper installation of NBR O Rings is vital to ensure a good seal. Always clean the groove and the O Ring itself before installation to eliminate any debris that could compromise the seal. Lubrication is recommended only when specified, as incorrect lubricants can damage the O Ring material. When placing the O Ring in the groove, ensure it is not twisted or stretched beyond its limits.
Regular inspection is key to maintaining the integrity of NBR O Rings. Look for signs of wear, such as cracks or tears. Environmental factors like temperature changes and exposure to chemicals can shorten the lifespan of the O Ring, so it's wise to replace them periodically. When storing NBR O Rings, keep them away from direct sunlight and high temperatures to prevent degradation.
It’s essential to monitor the performance of your NBR O Rings regularly. Signs of leakage, loss of pressure, or visible wear mean it's time for a replacement. Additionally, factors such as the age of the O Ring and the frequency of operation will also influence how often they should be changed.
