Swage Fitting Leaking / Vintage Air / Need Help

[bigboi]

I have a vintage air system and the high side of the compressor swage fitting is leaking. I put about 3 cans of R-134 in a few months ago and the A/C temp was getting warm. I hooked up the gauges and put a can of UV and 2 cans of R-134 in there and now the low side is at 40psi with high side at 270psi.

I ran the car around today with A/C on high and I took the black light to the engine bay. I notice the swage fitting on the high side of the compressor to the hose is leaking. This is the only leak I found so far.

These swage fittings don't use o-rings do they? I have taken the compressor off a few times lately and for some odd reason I think I lost an o-ring. A friend told me swage fittings don't use o-rings, but I am not sure if he is right or not?

Thoughts? Suggestions?
