This kit contains o-rings made of Buna Nitrile 90 durometer material, also known as BN90 or NBR90. Buna 90 is a common material used in ORS Flat Face seal applications due to its resistance to many hydraulic fluids and its flexability/sealability in low temperatures. The included size chart on the front of the kit makes sizing up o-rings quick and effortless. O-Rings are conveniently sorted by size in a shatterproof Flambeau divider box.
