I am changing out the evaporator coil on my old SZ Model 532 refrigerator. Bought a new evap coil off ebay and it came with tubing connections that would fit the existing suction line size, but the connection to fit the cap tube, although reduced down, is still too large for my cap tube. I thought about just brazing and "buttering" the gap between the cap tube and the evaporator inlet, but then I thought that maybe I could just go buy the proper sized conical reducer fitting that you typically see used when cap tubes are joined to small copper lines.
I went to a couple of my local HVAC supply houses including Gemaire and Johnson Supply and none of them even recognized an old sample I had of the conical reducer fittings which are commonly used with cap tubes. I went to my local SZ dealer and the parts department girl could not recognize the fitting and said come back in the morning and talk with one of their techs.
I then decided to go online and see if I could fine a source on these conical reducer fittings for cap tubes and after many search attempts, I found nothing! There are plenty of suppliers for cap tubes themselves, but I never saw a single fitting for adapting a cap tube to a standard sized copper tube. Can someone please give me a web link to where I can order a cap tube fitting?
