All of the fittings I have are new beadlock crimp fittings...except the double horse shoe adapter at the compressor...which is rare at #12 suction and #8 liquid (most are #10 and #8) the high pressure line had an integral crimp, not a ferrule, so I got a braze on beadlock fitting. For the life of me I cannot get the aluminum to flow, and blew a hole in the side of the tube twice. Using map gas and blue demon triple play low temp 1/8 brazing rods...I can sweat copper all day long but can't seam to get aluminum going...it's the last thing I need to finish for my double aux evaporators. Any suggestions?
