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.

What to expect: This item includes 180 O-Rings in a Flambeau plastic divider case with "Captain O-Ring" branded packaging.

Manufactured and warrantied against defect for one year by Captain O-Ring LLC. "Captain O-Ring" is a registered trademark of Captain O-Ring LLC.
