Shimano BH90 Olive and Insert

These specific fittings are designed exclusively for the Shimano SM-BH90 brake hose system. They are not compatible with the older SM-BH59 standard, so check your hose model markings before purchasing to ensure a proper fit.

Yes, you will need a hose cutter for a clean, square cut on the hydraulic line and a dedicated needle driver tool to press the insert into the hose without damaging it. Using pliers or a hammer can deform the insert or crush the hose, leading to potential leaks.

No, you should never reuse these parts. The olive is designed to crush and deform onto the hose to create a permanent, airtight seal during the initial installation; once removed, it cannot provide a reliable, leak-free connection again.

No, this pack contains components for only one connection point. You will need to purchase two separate packs if you are shortening or replacing the hoses on both your front and rear brakes.

The gold color is simply an anodized finish used by Shimano to distinguish the SM-BH90 insert from other models. It helps mechanics quickly identify that the part is compatible with high-pressure BH90 systems rather than the lower-pressure BH59 standard.
