Nitrile o-rings are very popular and are a cost effective solution. They are ideal for use as seals on pumps and drive belts, and are used in many other applications such as in the plumbing and agriculture industry. They serve as a barrier, preventing the leak paths between the sealing surfaces.
Advantages include its simplicity of construction and suitability for both static and dynamic applications. The most important sealing characteristic of an o-ring is its resistance to compression set or residual deformation. It is good for applications that need to endure fats, greases and high temperatures.
