I've never had a problem with my camlocks leaking. Yes, my though was to use it for cold-side transfers, in which case the beer will be going from keg to keg. I've never seen a keg with a TC, so there would be at least one fatlock/ quick disconnect involved on each hose anyway.Main reason was that TC is really the only true airtight under pressure fitting. I've found camlocks can be leaky, QD's highly depend on the o-ring same with the snaplock etc. Just depends what purpose you want to use the super sucker for. I had assumed cold side transfers which means you need TC even from a sanitation perspective.
