ST-R9120 Funnel Adapter & O-Ring

Since Shimano's bleed funnel doesn't fit directly, make sure you have the Shimano ST-R9120 Funnel Adapter & O-Ring handy before bleeding and adding more fluid to your road disc brakes. This necessary kit connects the overflow funnel to the brake lever bleed port for easy installation, bleeding, and re-filling.

  • Adapts funnel reservoir to brake lever bleed port
  • Includes threaded adapter and O-ring
  • Compatible with Shimano's R9120, R8020, R9170, and R8070 brakes

Necessary for bleeds

  • Familiarity: I've used it several times

This piece is an absolute must for bleeding Shimano road brake series R9120, R8020, R9170, R8070, and 7020. Shimano changed the size of their lever bleed port so the original funnel design won't thread in. Using this adapter was easy enough when paired with the funnel that comes in TL-BT03.

Thank you for posting this! I have searched far and wide and there was no info anywhere else that clarified / confirmed that this adaptor has the larger diameter thread required for the latest road disc master cylinder.
