Product: Olive connector bicycle oil disc Key benefits Reliable, leak-free braking: CNC-machined body and smooth threads produce a tight seal that prevents oil leakage and keeps hydraulic braking consistent. Durable under real use: Stainless steel, copper, and silicone construction plus the five-wire oil needle deliver long-lasting performance and resistance to cycling stresses. Fast, correct fit: Designed to match common hydraulic hose sizes so installation is quick and secure, reducing downtime and the risk of improper assembly. What it does for you Eliminates oil leaks that can degrade braking performance or require repeated maintenance. Restores a secure hose-to-caliper connection after wear, crash damage, or when replacing brake lines. Supports reliable braking for demanding rides, long-distance use, or frequent servicing. Compatibility and specifications Compatible with: SLX ZEE saint BH90 M640 M7000M8000 M8020 M820 M9000 M9100 M9120 hydraulic disc brake systems. Hose fit: Designed for oil pipes with an outer diameter of 5 mm and inner diameter of 0/2.1/2.3 mm. Materials: Stainless steel, copper, silicone. Manufacturing: CNC processing with smooth thread for a precise, secure connection. Includes: Olive connector and five-wire oil needle for robust, leak-resistant assembly. Practical use scenarios Replace a worn or damaged olive connector after a fall to quickly restore safe hydraulic braking on compatible systems. During routine brake maintenance or bleeding, install the connector for a secure, leak-free hose termination. For bike shops or mechanics servicing Shimano-compatible systems, use this connector to ensure a durable, professional repair. Why choose this connector Precision machining and quality materials reduce the chance of oil loss and unpredictable brake feel. Fits the common hose dimensions used by the listed models, making it a straightforward replacement part. Built to withstand regular riding conditions and repeated maintenance without compromising sealing performance.
