Metric O-Ring Kit N90

In terms of chemical resistance, 90 durometer nitrile is similar in every respect to that of the 70 durometer variety.  It has excellent fuel and oil resistance.  Also, nitrile does reasonable well in multitude of other environments.  The advantage of a harder material (90 vs. 70 durometer), is that the material has better wear and extrusion resistance.  Meaning that this compound is better suited to handle a harsher wear environments or high internal pressures, that 70 durometer nitrile would normally not be able to withstand.
