...Here's the solution that worked for Me, when I Installed a New P.S. pump on a GMC Truck, and the Hose Fitting was Different from the (Removable) Adaptor, on the Original (Old) Pump.
I turned the Two Pieces with the 'Ends' I need to work, on the Lathe to Mate with a .002" Press fit, degreased with Acetone, smeared a thin film of Locktite RED on the opposing surfaces and pressed the Two Parts together on a Hydraulic press. BOOM! An Adaptor. It works, No Leaks!
Be sure to cap the Flare so as to Not Damage it, in the Press.
If this procedure can hold the pressure of a P.S. Pump, it can certainly hold the Pressure of a AC Pump.
Steve, If You do not have access to a Lathe, send Me the Parts with a Clear Blueprint of what You need, and I will Machine, and assemble them for You. At No cost to You, for the 'Cause'.
