What does the fam think of these? They use a ratcheting mechanism I’ve never seen before, where a sleeve (I guess you call it) that grips the nut rotates inside the wrench head. (Flare nut wrenches are like open-end wrenches, except they reach around the the nut more. Often used in plumbing or automotive, where a flare nut might connect a metal vacuum line, for instance, to a manifold.)
Gearwrench makes a ratcheting flare-nut wrench, but it has a hinged jaw that slips when you turn it one way, and grips when you turn it the other. Maybe it opens wider than the Tribus design, but maybe it’s weaker.
It’s pronounced “Tree-bus,” it seems. Made in America, and super-expensive. But they look pretty nice.
