OK - finally GOT TO THE BOTTOM OF THIS !!!!

Yes, I still have the old hose, and I have considered that. It's the high pressure hose only.
I was wondering if there's a trick to get the hose fittings to seat completely
? I guess I figured that would be a no-brainer...

It seems like this high pressure hose is only from one manufacturer, in China, sold at both Autozone and O'Reilly and others as different brand names like Murray or Four Seasons or Everco, all with same sticker with Texas address and stating made in China. This part has been discontinued through Nissan.

So I think this will leak refrigerant again. The O-ring itself it NOT visible through this gap. I don't feel like trying to hammer on the fittings ends, plus access there is not so good.
Today, had to return to Phoenix to investigate an electric water heater leak discovered by my youngest daughter (it's at the top, may be a connection, but may need a new WH). Once there, I located my original AC line and matched it up to the 2nd AC line (one Murray from O'Reilly, one 4 Seasons/Everco from Autozone, same exact hose, same sticker with Texas address on the hose, even though made in China). The cylindrical fitting on the aftermarket fittings extends 14mm, yet the cylindrical fitting on the original Nissan unit extends just 9.5mm. My math skills tell me that's 4.5mm difference, a TON !!! I had already ground off about 2.5mm of the 1st aftermarket hose/fittings, but it looks like I was at least a full 2mm shy, no wonder these ends did not fit flush in the condenser or compressor !!! The O-ring looks to be in the same position on both, but I cannot believe that everyone is grinding these shorter. See photo:
I don't know if the computer listing is wrong (hose is correct length and metal parts the same shape as the original Nissan) just the cylindrical metal protrudes too far, or if someone botched it during set-up in China. Anyways, I cannot be the first person to have this issue, I'll be calling 4 Seasons/Murray tomorrow.
The 4 Seasons web site does list #56134 as the correct discharge hose assembly for the 1998 Frontier...I don't know whether to let it just run fine (like on the 225 mile trip today) until it "might" spew out someday through the O-ring, or be proactive and remove the hose assembly and grind both ends down even further to match the original assembly so it will fit flush and re-evacuate and re-fill.....
