R134a adapter part numbers and modifications

This post was updated on .

I finally found the R124a adapters with valves, thread here, and modified them so I didn't have to discharge my system to install them. They're from Factory Air and I got them at Advance, who lists them under the Factory Air part numbers.

Low 1/4" Factory Air #59976

High 3/16" Factory Air #59978

The normal way to install the proper adapters with schrader valves is to remove the valves from the ports on the vehicle first. I couldn't do that because I charged the system with the low-side adapter (which actually does work) from the cheesy universal kit before I realized the high-side adapter wasn't working, so I pulled the valves from the new adapters and shortened them by clipping the inside ends and washers off and dremeling down the sleeve. Now I have adapters with pushrods that open the valves in the original ports. Therefore for my next concours show all I have to do is remove the adapters and screw on the original caps! The judges'll never know. Pics below.

If you charged the system, it is working and holding PSI then why the need for the adaptors?
I run into the same problem, no high side gauge, when I charged my system a few weeks back.
My system is working so I am going to leave it as is and looks factory R12.

High side is needed to see what the high side pressures are doing. Plus if you have a newer recovery machine, they wont work without the highside as they alternate high side to low side for recovery.

Clearly you're not OCD enough. By god I want to connect my gauges and make sure my system is tip-top! Even if it behaves that way! Anyway, I got my gauges hooked up and I'm running 26-220 at 80F. The register is showing 36F. So I think I'm good.
