Shimano BH90-SB Brake Hose Olive and Connecting Insert

What Do the Shimano BH90-SB Olive and Insert Do for Your Brake Hose?

The Shimano BH90-SB brake hose olive and connecting insert are the two small fittings that create the fluid-tight seal between your hydraulic hose and the brake lever or caliper body. The barbed connecting insert anchors into the end of the BH90 hose while the compression olive crushes slightly against it during installation to create a leak-free, high-pressure seal. These fittings are consumed every time a hose is cut and refit, making them essential to keep on hand for any mechanic doing brake bleeds or hose length adjustments.

These fittings are specific to Shimano's BH90 high-pressure hydraulic hose used with current Dura-Ace, Ultegra, 105, GRX, and XT disc brake models. They are not interchangeable with BH59 hose hardware, so confirming your hose type before ordering matters. An inexpensive but critical part of maintaining a clean, bubble-free hydraulic system.
