Ccvm build ?

[aarons13]

First off am sorry if not asking this ? Properly bear with me.ok does a ccvm build require a cap of some kind to keep vapor from escaping at to top where a csst or copper condenser would be used? Also with that same csst or copper which ever use,require being adjusted up and down to unblock where fluid would crossover the tee to get to a shotgun type condenser for full product? Can someone message be please explain this part of the ccvm? Thanks
