Our nitrile O-rings are one of the most versatile O-ring choices out there. Offering good mechanical properties and resistance to oil based lubricants and greases, there are many applications requiring these O-rings. Used widely in multiple industries, we supply nitrile O-rings in a variety of shore hardness and specialist compounds.
Why choose nitrile O-rings?
Nitrile elastomer, also known as NBR or Buna, is an economical elastomer which is extensively used in a variety of industries. They are good general purpose seals with some attractive properties, including:
- Tear resistance
- Wide temperature range (-50⁰C to 120⁰C)
- Resistant to water, petroleum oils and some hydraulic fluids
- Low compression set
- Good abrasion resistance
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. As a material, it’s used widely in agriculture, dairy industries, mining, plumbing, rail and automotive industries.
Choosing your nitrile O-rings
