Ratchet Opening Single Ended 12-Point Flare Nut Wrench, Metric 13mm

Flare nut wrenches are designed specifically for gripping and turning soft metal fittings like those found on brake lines, fuel lines, and hydraulic systems. They’re a hybrid between an open-end wrench and a box-end wrench, offering more contact with the nut while still being able to slide over tubing. They have a gear mechanism on the single end head that allows the wrench to rotate freely in one direction without removing the wrench head from the fastener and repositioning the wrench. The ratcheting wrench head allows a line or other obstruction to pass through it, then closes for full contact around the fastener. The 12-pt. design has additional grooves that make it easier to connect with the head of the fastener and connect at more angles for better accessibility.
