Hello. New to the forum, but I've already purchased a lot of Alphacool products and one of them I have a question about. The TPV quick releases that came with the Eisbaer Aurora and the Eiswolf 2 5700XT I want to replace with the industrial version that doesn't have the screw part. I've tried to remove the TPV hose from the fittings, but they won't budge at all. I've tried everything I could think of to get the metal lock ring to come out with the tubing, but it just won't come out. I'm completely confused as to what to do at this point. Has anyone had any luck disconnecting the hoses from these quick releases? I want to reuse them for a friend, but the way they locked in and how cheap they are makes me think they're disposable or something.
