If you need a durable, highly resistant material for a tough application, there are many benefits to highly saturated nitrile rubber. This material offers temperature and fuel resistance, abrasion, wear, and compression set resistance, and superior chemical resistance. With an operating range from -40°F to 300°F, HNBR significantly extends the temperature limits of standard nitrile materials, making it ideal for automotive, oil and gas, and industrial applications. HNBR is widely used in automotive systems, oil and gas equipment, and industrial machinery where exposure to heat, oil, and mechanical stress is common.
HNBR provides excellent resistance to:
HNBR may not be the best choice for applications involving strong acids, chlorinated hydrocarbons, esters, ethers, or ketones, where alternative materials may provide better performance.
While NBR is a widely used general-purpose elastomer, HNBR offers improved performance in more demanding environments. It is often selected when applications require higher temperature resistance, better mechanical strength, and longer service life.
Whether you're replacing standard nitrile or specifying a higher-performance material, North Coast Seal can help you determine if HNBR is the right fit for your application.
"*" indicates required fields
HNBR is commonly used for seals, O-rings, and gaskets in automotive, oil and gas, and industrial applications where heat, oil, and mechanical stress are present.
HNBR is a hydrogenated version of nitrile rubber, offering improved heat resistance, better chemical stability, and longer service life compared to standard NBR.
HNBR typically operates between -40°F and 300°F, making it suitable for higher-temperature applications than standard nitrile materials.
Yes, HNBR provides excellent resistance to petroleum-based oils, fuels, and lubricants, which is why it is widely used in automotive and industrial sealing applications.
