US Industrial Kit N90

Nitrile, a copolymer of acrylonitrile and butadiene, is a good multi-purpose compound.  It does well in most types of environments, and is generally resistant to fuels, oils, water and many other fluids. When compared to other elastomers, nitrile has good mechanical properties and wear resistance. The O-rings in this kit are made from 90 durometer hardness, which increases resistance to extrusion, but reduces low temperature flexibility
