Park Tool MWF Metric Flare Nut Wrench - MWF2 7 and 9mm

Ingenious little tools for working on your brakes!

Rather than using a standard open ended wrench, and only engaging half of a compression fitting for your brakes, these engage the entire thing, much like a socket, eliminating any chance of damaging the delicate fittings.

Who's this for: People bleeding or removing hoses from their brakes, and want to minimise any chance of slipping and damaging their fittings.

Pros: Clever, semi-open box design fully engages the tool onto the compression fitting of a hydraulic line.

Cons: Nothing, these things are awesome!
