Hello and thank you in advance. I bought the EK-HD 10/12 millimeter adapters for my water cooling setup. Do I simply stick the tubing into the adapter? It's not supposed to come apart for like a compression fitting is it? I crammed the end of a tube in the fitting and it goes in snug. I'm just used to all the video tutorials I've seen having compression type fittings I guess. Thanks for in advance for helping with a stupid question. I appreciate it
