big male flare by solder connectors

archibald tuttle

been working on a prototype chiller system discussed here and I want to first go with short connection between condenser and evaporator for testing and then put in full line set so I'm planning for flared lineset for change out.

Parker has the style of fitting I want , e.g. 46F-12-12 , but I need the equivalent of a 46F-14-14 for the return line. (those are dash part numbers so they are 16ths of an inch. Parker apparently only makes up to a 46F 12-14 so i can get 7/8 on the solder side but not on the flare side. i could adapt the end of the line set but I'm just worried if i make a little squeeze like that close to the compressor it could cause a little condensation of refrigerant. With a longer lineset I could mseparate for the last 5 feet and take the insulation off the suction line so that ambient air and the pressure loss of return both contribute to maintaining superheat through that slight restriction i'd be creating but maybe there is another manufacturer who takes these fitting up to 7/8" both sides . . .

thanks

I have a flaring tool that does up to 1 1/8 but have never flared that size. Most flaring stops at 5/8 although I have seen3/4 od and 7/8 od fittings they are seldom used and most supply houses have limited quantities if any. Not saying they are not available. People complain about flare leaks.

Carrier uses a type of compression type fitting on their chillers maybe they are "Swedgelock" don't know the name. That may be a possibility
