Nitrile O-Rings, Seals, and Other Parts
Nitrile rubber – also called nitrile-butadiene rubber NBR rubber, and Buna-N – is a synthetic rubber that provides excellent resistance to petroleum-based oils as well as mineral and vegetable oil. Timco Rubber can work with your business to design and provide nitrile seals, NBR o-rings, and other parts customized for the specific needs of your applications.
Nitrile Rubber: A Material Made for Oil Resistance
Unlike natural rubber and other materials, nitrile gaskets and other parts are more resistant to heat aging. This feature is a key advantage, as it allows nitrile to not harden and lose its damping capability as quickly as natural rubber and other solutions. Nitrile rubber is also a great material choice for applications that require abrasion resistance and metal adhesion.
Due to its versatility and strong resistances, nitrile material is used in applications involving not only oil, fuel, and chemical resistance, but also those that require resistance to heat, abrasion, water, and gas permeability.
