So I decided to do the nitrogen pressure test anyway. The cowboy way probably would have worked, but I really only want to release the refrigerant once!
Question...do you know where I can find an adapter for the 7/16" 20 fitting coming off my regulator on the nitrogen tank? I need to connect this to my 1/4" fitting on my refrigerant hose. I've been able to find most everything else on ebay or the common online HVAC supply stores except this.
