NBR O rings, also commonly referred to as nitrile O rings or Buna N O rings, are indispensable components in sealing applications across various industries worldwide. We meticulously craft these seals from NBR (acrylonitrile butadiene rubber), representing a pinnacle of engineering excellence. They offer exceptional resistance to oils, fuels, and other petroleum-based fluids. At Exactseal, we take immense pride in our extensive selection of O rings. Each ring is meticulously engineered to deliver reliable sealing solutions for a diverse range of applications.

Nitrile rubber’s robust mechanical properties and wear resistance make NBR O Rings reliable, although they aren’t suitable for high temperatures, ozone, or UV exposure. These O Rings come in diverse hardness levels, measured on the Shore A durometer scale (usually ranging from 70 to 90 Shore A). A higher durometer indicates increased hardness and compression resistance.

Versatility of NBR O Rings

The versatility and durability of NBR O rings make them the go-to choice across industries spanning automotive, manufacturing, and hydraulic systems, among others. Engineered to withstand the harshest operating conditions, NBR O rings exhibit unparalleled resilience against oils, fuels, and hydraulic fluids. The unique composition of Buna N imparts superior compression set resistance. This ensures optimal performance in both static and dynamic sealing applications, thereby enhancing operational efficiency and minimizing downtime.
