as i mentioned, with the YJ 4 valve manifold there is zero 134a waste, its also an EPA issue to vent 134a. with a 4 valve manifold you close off all the valves, switch cans, open vac and ref valves, vac it down, close vac line, open can, open lo side and fill, etc. purging can still be done, but no need.
and no, i dont have a 26oz can, i have a 12 & 14.
