Jagwire Shimano Olive

Yes. Olives are designed to be crushed once to create a permanent, airtight seal. Once they have been compressed, they cannot be reused safely, so you must install a new one whenever you disconnect the hose from the lever or caliper.

This olive is compatible with most standard Shimano and Tektro hydraulic systems. However, always verify your specific brake model's service manual, as some high-end or older systems may require proprietary fittings.

Generally, yes. As long as the hose diameter matches the standard Shimano/Tektro hydraulic hose specification, this olive will function correctly. The critical factor is ensuring the olive matches the fitting requirements of your brake lever and caliper.

No, this listing is specifically for the compression olive. You will need to purchase the matching connecting insert separately if you are cutting your brake lines or installing a new hose.

The gold color is simply a cosmetic finish used by Jagwire to distinguish their aftermarket components from stock parts. It does not indicate a difference in material or performance compared to standard silver olives.
