Ideal for riders or home mechanics servicing Shimano hydraulic disc brakes that use an SM-BH90 hose and want the correct genuine fitting for a clean, reliable hose connection.
The Shimano SM-BH90 OLIVE&CONNECTER INSERT is a genuine replacement fitting for Shimano SM-BH90 hydraulic brake hoses. If you're trimming a hose for a new bar setup, replacing a damaged line, or reconnecting a brake after internal routing work, this is the hardware that finishes the hose correctly so it seals at the lever as intended.
For workshop jobs, this is one of those small parts that saves a lot of frustration. The olive compresses to create the seal and the insert supports the hose internally, which is why using the right BH90-specific fitting matters. Real-world workshop guidance consistently points to poor sealing, fluid weeping and inconsistent lever feel when the wrong hose insert or olive is used, especially if BH90 and BH59 parts get mixed.
If your bike runs one of Shimano’s higher-power BH90 hose systems, this is the straightforward OEM choice. It suits a huge spread of Shimano road, gravel, MTB and trekking brakes that use SM-BH90 hose variants, so it’s the right item to keep on hand if you service your own brakes or want the correct spare in the toolbox before a hose cut or brake swap.
Made for SM-BH90 hose systems
Designed for Shimano hydraulic brake setups that use SM-BH90 hose variants, rather than older BH59 systems.
Essential for hose shortening and reinstallation
Use it when cutting a hose to length, reconnecting a lever, or replacing a damaged hose during brake servicing.
Correct hose support and sealing
The insert reinforces the hose internally while the olive forms the compression seal when installed correctly.
Helps avoid leaks and poor lever feel
Using the proper BH90-specific fitting reduces the chance of fluid weeping, connection failure or a spongy brake caused by mismatched parts.
Genuine Shimano replacement part
A simple OEM solution if you want the same style of fitting used across Shimano BH90 hose systems.
Broad Shimano brake compatibility
Works across many Shimano road, gravel, MTB and trekking brake combinations that are specified for SM-BH90 hose types.
General
Great for
Maybe not for
This is a hose fitting, not a size-based product. It is for Shimano SM-BH90 hose variants and not for BH59 systems. Shimano’s current compatibility chart shows SM-BH90 hose combinations across a wide range of road, gravel, MTB, urban and lifestyle brakes, but the exact hose variant and end fitting can vary by lever and caliper, so check your existing hose code before ordering.
vs Jagwire Pro Hydraulic Hose Fitting Kit for Shimano
A practical aftermarket alternative for Shimano-compatible hose work if you’re already building a full custom hose setup, but the Shimano part is the cleaner choice when you simply need the correct OEM BH90 fitting.
vs Clarks hydraulic olive and insert kits for Shimano-compatible brakes
A lower-cost workshop substitute in the same category, but this Shimano set is the safer pick when exact BH90 hose compatibility matters more than saving a few dollars.
Match the fitting to the hose, not just the brake brand
Shimano uses different hose systems across its hydraulic range. If your hose is SM-BH90, use the BH90-specific olive and insert rather than assuming any Shimano fitting will do.
Best replaced whenever the hose is disconnected
The olive is a compression part, so it’s smart practice to fit a fresh one when you remove and reconnect a hose during routing, shortening or lever replacement.
A clean hose cut matters
Even the right fitting won’t seal properly if the hose end is crushed, angled or rough. A square, clean cut and a properly seated insert are the difference between a tidy install and a frustrating leak.
Useful spare for internal-routing bikes
If your frame or bar routing means disconnecting hoses during transport or maintenance, keeping one of these in the toolbox can save a job from stalling halfway through.
