High Side Valve Adapter?
Ok, so I read through the previous thread on this and didn't find a definitive answer. This is a stock 88 F250 with R12 AC as it came from the factory so it has not been converted to R134a and I have no plans to do that. I do however need to troubleshoot it and recharge it with R12, R406a or Hotshot.
I have an R12 Manifold Gauge set. It has 1/4" hose fittings. The low side hose fits the low side valve just fine. The high side hose fitting is too large so an adapter is needed. Again, this is the stock Ford R12 high side valve. When I search adapters, I find all kinds of descriptions but nothing that says they fit the 88 vintage Ford high side valve.
Does anybody know where to order one, what the part number is, and/or what the correct description is?
Thanks.....

Thanks, that appears to be the right one so I ordered it. In the meantime, I got a screw on fitting for R134a conversion (its removable) and used my R134a adapter for my manifold gauge set.. That let me read the high side pressure successfully.. I will be recharging with R12 so will remove the valve adapter after I finish troubleshooting and recharging so it still has the correct fitting on it...
