  Why Buna (Nitrile) O-Rings?

  Buna, scientifically referred to as Nitrile Butadiene Rubber (NBR), is a synthetic rubber copolymer of butadiene and acrylo nitrile. Buna-based o-rings, Backup Rings, X-Rings, and Square Rings have earned their place as the preferred choice in numerous applications due to their unique balance between flexibility, resistance, durability, and affordability.
  This balance positions Buna o-rings as a stand-out choice for various demanding industrial applications. As a leading provider, Global O-Ring and Seal understands the crucial role of these components and is committed to offering superior quality Buna-based products to cater to diverse industry needs.
  
  Applications of Buna (Nitrile) O-Rings
  
  Given their exceptional properties, it's no surprise that Buna o-rings find application across various industries, including automotive, aerospace, oil and gas, agriculture, and food processing.

  Automotive Industry

  In the automotive industry, Buna o-rings are integral to the overall operation of various vehicle systems. Their excellent resistance to petroleum-based oils and fuels makes them ideal for use in fuel and oil systems. They maintain tight seals even under high pressures and temperatures in these settings. Commonly, they are in fuel injectors, oil seals, fuel pumps, and carburetors. Their ability to withstand high temperatures also sees them used in the heat-intensive environment of engines, specifically in areas such as gaskets and cooling systems.

  Aerospace Industry

  The aerospace industry heavily relies on Buna o-rings, especially in fluid power systems that demand excellent resistance to compression set and a wide operating temperature range. Buna o-rings ensure leak-free operation under the most challenging conditions, a vital aircraft safety and efficiency requirement. Moreover, Buna's resistance to a range of aircraft fuels, hydraulic fluids, and lubricating oils makes it an excellent choice for this sector.

  Oil and Gas Industry

  The demanding environment of the oil and gas industry also leverages the strengths of Buna o-rings. They are used extensively in drilling equipment, pumps, valves, and other downhole tools. These applications demand seals that perform under extreme pressures and temperatures. With their excellent resistance to oil-based fluids, Buna o-rings are perfect for such applications, reducing the risk of leaks and expensive downtime.

  Agricultural Industry

  In the agricultural sector, Buna o-rings find their way into various equipment such as tractors, irrigation systems, and harvesting equipment. In tractors, they're in hydraulic systems, fuel lines, and cooling systems. Buna o-rings also prove vital in irrigation systems, especially those that use fertilizers or other chemicals, due to their resistance to many agricultural chemicals. The substantial temperature variations typical in this sector pose no problem for Buna o-rings.

  Food Processing Industry

  Another industry where Buna o-rings are essential is the food processing industry. The material's resilience, durability, and resistance to a wide variety of oils and fats make it an ideal choice in this sector. They are found in numerous applications, from processing equipment to storage and transportation systems, ensuring safe and hygienic handling of food products.

  
  O Ring are available in the following elastomers:

  Aflas^® or Kalrez^®(FFKM)
  Acrylate Rubber(ACM)
  Butyl Rubber(IIR)
  Ethylene-propylene (EPR, EPDM)
  Ethylene Acrylate Rubber(AEM)
  Fluorocarbon (FKM/FPM)
  Fluorosilicone(FVMQ)
  Hydrogenated Nitrile (HNBR)
  Liquid Silicone Rubber(LSR)
  Neoprene Rubber(CR)
  Nitrile Rubber (Buna-N/NBR)
  Natural Rubber(NR)
  Polyurethane(PU)
  Silicone Rubber Styrene-butadiene Rubber (SBR)
  
  Different elastomers have different compatibility with various chemical elements and their characteristics. See the table below for more material knowledge to order the most cost-effective o-rings from us.
