Captain O-Ring’s 180 Piece ORS Hydraulic Buna90 (BN90) O-Ring Kit includes 8 sizes and 180 total o-rings. The kit includes #4 (1/4″ Flat Face), #6 (3/8″ Flat Face), #8 (1/2″ Flat Face), #10 (5/8″ Flat Face), #12 (3/4″ Flat Face), #16 (1″ Flat Face), #20 (1-1/4″ Flat Face), and #24 (1-1/2″ Flat Face) o-rings.
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.
Note: These are round o-rings used in ORS Flat Face Fittings. The o-rings themselves are round and not flat.
