So I'm posting this for a friend, he has an ijoy maxo and a smok tfv8 tank was all working great until today. His tank popped off and won't thread back in it almost as if the 510 connection is too big now to catch the threads of the tank. We tried screwing his tank into other devices with no problem but other atomizers will not fit into his maxo, I'm thinking something is off with the 510 connection but for the life of me I can't figure out what it could be, anyone have any idea. The tank is not removed very often and all the threading seems fine, it's as if it has expanded and won't allow any atty to be connected. Thanks in advance for any help.
