Nitrile O-Rings

Versatile Sealing Solutions for Various Industries 

When it comes to O-ring choices, nitrile O-rings stand out as one of the most versatile options available.  These O-rings offer good mechanical properties and excellent resistance to oil-based lubricants and greases, making them ideal for a wide range of applications across multiple industries. 

What are Nitrile O-Rings? 

Nitrile O-rings, also known as NBR or Buna O-rings, are an economical elastomer that is widely used in various industries.  They offer a range of attractive properties, including good tear resistance, wide temperature range (-50°C to 120°C), resistance to water, petroleum oils, and some hydraulic fluids, low compression set, and good abrasion resistance. 

Applications of Nitrile O-rings 

Nitrile O-rings are particularly good at sealing against fats and greases at higher temperatures, as well as in environments where oils and petroleum-based fluids are present.  They are widely used in agriculture, dairy industries, mining, plumbing, rail, and automotive industries.  These O-rings are tough and robust seals, making them ideal for physically demanding applications.   

Choosing Your Nitrile O-Rings 

Choosing the right shape, size, and compound for your nitrile O-ring is crucial to ensure a reliable seal.  It’s essential to consider the specific application and environmental factors when selecting the right nitrile O-ring for your needs.  Our team of experts can help you choose the best material and specifications for your application to ensure optimal performance.  For further information, please visit our customer portal or contact
