Hi piffpuff you unscrew the bottom plate inside the plate there is a lip the o'rings i put on the the outside the lip.Putting o'rings on this cuts down the space between the airflow and the plate tightens the draw a lot.I Tryed 1.2mm thickness first made it better but 1.5mm thickness made it even better for me

Which airflow positive post are you using? The 2 x 1.2mm, 1 x 1.8mm or 1 x 1mm post? This Coppervape clone did come with all three positive posts didn't it?
