icemeister, Although that video is interesting, it is not feasible for commercial applications. First, being clearance for that monstrosity of a crimping tool. Secondly, the abuse the equipment endures. I'm curious as to why a completely evacuated system would require crimp fittings and not being able to use a torch.
Every leaker is going to require an evacuation. If they begin to use this on bigger systems, I can see techs being injured and equipment being damaged while trying to take shortcuts. I guess it's a good way to weed out the hacks.
