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.
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)
