A suitable spare for home mechanics, workshops and anyone servicing or shortening a Shimano hydraulic brake hose that uses the SM-BH59 fitting system.
The Shimano SB-BH59 Olive/Insert Unit is a genuine replacement set for servicing Shimano hydraulic disc brake hoses. It includes one brass olive and one brass connecting insert, providing the small but essential hardware used to secure and seal an SM-BH59 hose connection.
It is a practical choice when replacing a worn fitting, installing a new hose or shortening an existing line. Customer feedback reports a good fit on BH59 hoses and successful use during brake servicing, but hydraulic brake fittings must be matched correctly and installed to the relevant Shimano specifications.
Before ordering, check the hose and brake model carefully. BH59 and BH90 systems use different inserts; the published compatibility list includes systems such as Shimano BR-RS785, BR-RS505, BR-R785, BR-M4050, BR-M3050 and BR-M355. If you are unsure, confirm the exact hose type before beginning the job.
