No.153B Flare Nut Open Ring Wrench

DIN3118 Die forged
It is used for gripping the nuts on the ends of tubes. Similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening justwide enough to allow the wrench to fit over the tube, and thick jaws to increase the contact area with the nut.
