View our range of metric O-Rings here. Nitrile O-Rings have a working temperature range of -30 to +100 degrees C. Nitrile O-Rings are a common material for O-Rings because of its good mechanical properties, its resistance to lubricants and greases and because of it's relatively low cost. O-rings seal by mechanical deformation that creates a barrier to a fluid’s potential leak path between two closely mated surfaces. O-rings are typically installed in a groove that’s machined or molded in one of the surfaces to be sealed. Their rubber-like properties let the devices compensate for dimensional variations in the mating parts.
