Product description

Highlights at a glance

  • Our high-performance Buna-N (Nitrile) O-rings are engineered specifically to meet the rigorous demands of the oil and gas industry. Known for their exceptional resistance to petroleum-based oils, fuels, and hydraulic fluids, these NBR seals serve as a reliable and cost-effective solution for critical sealing applications. As a dedicated manufacturer, we ensure our Buna rubber O-rings provide a superior balance of mechanical properties, offering excellent compression set resistance and high tensile strength to maintain seal integrity in harsh oilfield environments.
  • Designed for both static and dynamic sealing, our Buna-N O-rings are available in a wide range of durometers, including 70 Shore A and 90 Shore A, to withstand varying pressure levels in downhole tools, valves, and pipeline components. These nitrile rubber seals are precision-molded to comply with international standards such as AS568 and metric specifications. Their robust construction makes them ideal for use in drilling equipment, gas compressors, and offshore platforms, where resistance to abrasion and industrial chemicals is paramount for preventing costly leaks and equipment downtime.
  • As a leading industrial seal manufacturer, we utilize advanced production technology and rigorous quality control protocols to deliver Buna rubber O-rings that exceed client expectations. We understand the high-stakes nature of energy infrastructure, which is why our nitrile sealing solutions undergo extensive testing for durability and thermal stability. Beyond standard sizes, we offer customized sealing solutions tailored to your specific project requirements, ensuring rapid lead times and global shipping for refineries, petrochemical plants, and oilfield service providers worldwide.
    • Frequently asked questions

    Buna-N O-rings (also known as Nitrile or NBR seals) are the industry standard due to their exceptional resistance to petroleum-based oils, fuels, and hydraulic fluids. For oilfield applications, they offer a perfect balance of durability, chemical compatibility, and cost-effectiveness, ensuring leak-free performance in pumps, valves, and pipelines.

    No, these terms all refer to the same material: Nitrile Butadiene Rubber. "Buna-N" is a common trade name, "Nitrile" is the chemical name, and "NBR" is the international abbreviation. In the sealing industry, they are used interchangeably to describe this highly oil-resistant elastomer.

    Standard Nitrile O-rings typically operate reliably between -40°C and +120°C (-40°F to +248°F). For extreme temperature requirements, we offer specialized low-temperature or high-heat NBR compounds tailored to specific downhole or surface environments.

    Yes. For high-pressure environments, we recommend using 90 Shore A hardness Buna-N O-rings. This higher durometer provides superior resistance to extrusion and permanent deformation. For extreme pressures (above 1,500 PSI), we suggest pairing them with backup rings for maximum safety.

    Absolutely. As a leading manufacturer, we produce a full range of AS568 standard O-rings, which is the most widely used size chart and global oil industry. We also supply a comprehensive catalog of Metric O-rings (ISO 3601) to fit any equipment specifications.

    We are an ISO-certified sealing manufacturer specializing in oil and gas applications. We provide factory-direct pricing, rigorous quality control (testing for tensile strength and compression set), and rapid global shipping. Our expertise ensures you receive "oilfield-grade" quality that minimizes equipment downtime.
