Captain O-Ring LLC Captain O-Ring 255 Piece Boss Hydraulic Bn70 Sae 900 O-Ring Kit (255Pc: 904, 905, 906, 907, 908, 909, 910, 911, 912, 913, 914, 916 Buna Nitrile Orings In Plastic Divider Case)

Nice set of o-rings in an awesome case. That's usually the problem with these kits, the case is junk and falls apart and your stuff ends up on the ground. Not this kit. Has all the common sizes and feel like quality o-rings.

Great set, fit very well and I guess only time will tell how long they last. Large assortment of sizes and all fit my machine so far. Great value for the price. Case is nice to keep them organized and it is not flimsy.

decent selection

Great product

I have HF's SAE and metric kits, and the boxes are mostly full. Why? because they don't fit anything. They are close but I think manufacturers deliberately make "O" rings that can't be replaced by any in these kits, LOL. I needed ORB "O" rings for hydraulic fittings I just had hoses, made for and the Captain -O-Ring kit fit and worked great, with NO leaks. I am happy.
