Looking to cut those brake hoses a little shorter? These fittings are what you need to attach the shortened hose to the brake lever. One set (includes one needle and one olive) is enough for one brake, so buy two sets if you wish to cut both your lines. This genuine Shimano replacement part is designed to fit the BH90 high-power hydraulic brake hose, standard on most (2012-newer) Shimano MTB disc brakes. It is NOT compatible with any other hoses besides BH90. Please refer to Shimano's official technical instructions for proper hose shortening procedures.
