Like their 70 durometer counterpart, 90 durometer nitrile O-rings are comprised of a multi-purpose rubber compound, acrylonitrile and butadiene that performs well in most environments. As with other nitrile O-rings, 90 durometer nitrile O-rings resist wear, feature good mechanical properties in comparison to other elastomers and are built to withstand fuel, oil and other fluids.
Two things differentiate this kit from our deluxe nitrile kit. First, it contains 436 O-rings, with a selection of 35 of the most often used AS568 Standard sizes. The 90 durometer hardness of the O-rings in this kit also makes them more resistant to extrusion while reducing their flexibility in low temperatures.
