HNBR O-Rings at NewDealSeals

When it comes to sealing solutions that need to withstand extreme conditions, HNBR (Hydrogenated Nitrile Butadiene Rubber) O-rings are the go-to choice for engineers and industries worldwide. HNBR O-rings offer a unique blend of resilience, temperature resistance, and chemical compatibility, making them ideal for applications in automotive, oil and gas, and many other industries. On this page, we’ll delve into the key benefits of HNBR O-rings and why they are the preferred choice for challenging sealing needs.

What are HNBR O-Rings?

HNBR O-Rings, or Hydrogenated Nitrile Butadiene Rubber O-Rings, are a type of synthetic elastomer sealing component known for their excellent resistance to a wide range of challenging environments. These O-rings are derived from nitrile rubber (NBR) and undergo a hydrogenation process that enhances their performance characteristics, making them ideal for demanding sealing applications.

Why choose HNBR O-Rings?

    

In comparison to NBR, HNBR O-rings offer enhanced chemical and weathering resistance. HNBR also excels in abrasion resistance, making it a compelling alternative to Viton® FKM. Additionally, HNBR exhibits superior low-temperature properties and tear resistance compared to fluorocarbon.

  • Exceptional Temperature Resistance:
    HNBR O-rings excel in high-temperature applications, withstanding temperatures ranging from -40°C to 150°C (-40°F to 302°F). This makes them a reliable choice for sealing components exposed to extreme heat.
  • Chemical Compatibility:
    HNBR possesses excellent resistance to a wide range of chemicals, including oils, fuels, hydraulic fluids, and industrial chemicals. This chemical compatibility ensures long-lasting and reliable seals even in harsh chemical environments.
  • Oil and Fuel Resistance:
    HNBR O-rings are particularly well-suited for automotive applications due to their exceptional resistance to motor oils, transmission fluids, and other hydrocarbons. They maintain their sealing integrity, reducing the risk of leaks and contamination.
  • High Tensile Strength:
    These O-rings exhibit high tensile strength, allowing them to endure mechanical stresses and pressures in various applications. This characteristic contributes to their durability and reliability.
  • Low Compression Set:
    HNBR O-rings have a low compression set, which means they can maintain their shape and sealing effectiveness over time. This property reduces the need for frequent maintenance and replacement, translating to cost savings.
  • Customization Options:
    Available in various sizes, shapes, and durometers, HNBR O-rings can be customized to meet specific sealing requirements. Their versatility allows them to adapt to diverse sealing challenges.

By choosing HNBR O-rings, you’re investing in sealing solutions that ensure the integrity and longevity of your equipment, ultimately contributing to the efficiency and success of your operations.
