NBR O-rings, also known as Nitrile or Buna-N O-rings, represent a crucial component in modern sealing technology. These versatile synthetic rubber seals are specifically engineered to provide reliable sealing solutions across diverse industrial applications. Composed of acrylonitrile and butadiene copolymers, NBR O-rings offer exceptional resistance to oils, fuels, and most hydrocarbon-based fluids, making them an industry standard for automotive, aerospace, and manufacturing sectors. The material's composition can be adjusted during production to achieve varying degrees of nitrile content, typically ranging from 18% to 50%, which directly influences its chemical resistance and temperature performance capabilities. NBR O-rings maintain their functionality across a temperature range of -30°C to 100°C, though special compounds can extend this range further. Their remarkable combination of mechanical strength, elasticity, and cost-effectiveness has established them as the preferred choice for numerous sealing applications. These O-rings demonstrate excellent compression set resistance and maintain their sealing properties even under significant pressure variations, ensuring consistent performance in dynamic systems.
