An adjastable wrench is the worst choice of all, since it is the easiest way to mess nuts. For the small flange (CF4-1/2 or CF63 in metric notations), as shown in video, this is not that bad compared to bigger flanges. A 1/2-inch (or 13 metric) fork (open-end) wrench would be the better choice, but the box-end or socket wrench would be the best choice for preserving the nuts in a good shape.
Thank you for this very helpful and informative video!
This also works without screws with Evac Chain Clamps system with Conflat Type Flange system.😉
