Home mechanics and workshops bleeding Shimano flat-bar hydraulic disc brakes.
The Shimano TL-BR003 is the bleed funnel for Shimano MTB, trekking and flat-bar hydraulic levers. It screws directly into the lever's M5 bleed port, so there is no separate adapter to lose and no gap for oil to leak out.
Top it up with Shimano mineral oil, push fluid up from the caliper, and watch the bubbles rise through the translucent funnel. When the bleed is done, drop in the oil stopper and unscrew the funnel without spilling the oil left in the cup.
It is the right part for a home mechanic doing their own Shimano bleeds, or as a replacement when an older funnel cracks or goes missing. For drop-bar Shimano levers, you want the road version, the TL-BR002.

Oil stopper
A plug that seals the funnel so you can remove it from the lever without spilling the oil left inside.
Translucent funnel
You can see the oil level and watch air bubbles rise out of the lever as you bleed.
Great for
Maybe not for
Fits levers with an M5 bleed port. You will also need Shimano mineral oil, a bleed syringe or bottle with tube for the caliper end, and a bleed block.
Level the lever first
Rotate the lever on the bar so the bleed port is level before you fit the funnel. Air rises to the highest point, and you want that to be the funnel, not a corner of the reservoir.
Pull the stopper last
Once the bleed is done, fit the oil stopper before unscrewing the funnel. The leftover oil stays in the cup and you can pour it into your waste container instead of onto the brake.
