The steel 3/8" A/C nut on the liquid refrigerant pipe on the condenser side is corroded and stripped. I plan on cutting off the nut,putting a new one on, with a "Splice-loc" line repair coupling. A new line is available, but it looks much easier and safer than running into another cranky fitting, and possibly having to replace the evaporator also. Where can i find another nut! Anybody got an extra !!!
