I believe you are referring to the scuba tank valve "dip tube". The dip tube should just screw into the tank valve. Remove the valve from the tank, turn the tank upside down to retrieve the dip tube, then use a cloth or rubber covered channel lock pliers to screw back in...not extremely tight, but snug. Then screw the valve back onto the tank and only hand tighten.
