AC low presure fitting??

[GNandTTA]

Am I missing something here? Just bought a Yellow Jacket R12 manifold set and the high side connects fine. But the low side port on the GN is smaller than the fitting on the Yellow Jacket manifold. The Yellow Jacket connects fine to all my other cars. Is there some special adapter that is needed. It looks the same as the TTA low pressure port just smaller in diameter. Any ideas??

Not sure what a "yellow jacket" is? But the A/C low pressure port on the dryer is larger than the high pressure port fitting on the A/C line near the radiator. All this applies to '86-7 Regals, other cars, years are/may be different.

Thanks Nick. I just meant the brand Yellow Jacket. Someone else told me the low pressure port is by the radiator.
So then the high pressure port needs the adapter. Where do I get one of these?

Glad we got that straightened out!

A "good" auto parts store should fix you up.

ac delco makes a real good brass adapter-about $12.00 but will last forever without stripping the threads
