O.K., So being a Harley Mechanic all my life I'm no expert on air conditioning. That said. None the less I'm trying to repair / upgrade my air con. So, I purchased a aftermarket condenser. my issue is with hooking up the lower / liquid line. my original condenser has a fitting like this,

My new condenser has the opposite of this, or the female side as it where. And it came with a fitting like this,


As you can see it has a male end just like my old condenser. which is fine as this male O-ring fitting attaches fine to the new condenser, the problem is my liquid line is a metal line. what I would need to connect it is a 90 degree elbow like the one they included with the condenser, but with 2 male O-ring ends, not one barbed hose end.
In my looking these things are called out by number, as in 6 8, 10 etc. How do I know what number size this is? clearly the factory line is the same size. I just don't know what that is. The upper line, (from the compressor), is definitely larger but not a concern as I have new line with correct end to fit.
Need to join factory hard line to new condenser with a 90 degree fitting with 2 male O-ring ends of correct size.
Anyone know the number size and where if anywhere such a fitting could be purchased?

 

Brother,
I have done much A/C work on these cars and my best recommendation is this; save yourself the headache of trying to jerry-rig this fitting and the almost gauranteed leak that will develop at that point, return that condenser and buy a direct fit. You will be much happier with the install and the results.
Cheers, Greg

 

You can’t or don't wish to return the condenser, a quality AC shop that deals within classic vehicles should be able to use their marchioness to attach the fitting you require. My shop had to add the valve for adding Freon because the one I ordered from Corvette America didn’t have one on the hose. In think the added valve was about $ 25.

 

Thanks for the replies. As per returning it to the States. cost around 100 dollars. ordering a direct fit parallel flow condenser. about 500 dollars delivered to North Queensland.
Having a fitting custom made? Not sure, nothing Automotive comes cheap around here. None the less. likely to be way less than the 600 dollar option.
I looked at every Air-Con fitting on Summits site. nothing.
I will look into getting one made locally. And I really doubt that just one more O-ring fitting will guarantee a leak.
I'll post back my results.

 

The liquid line should be -6 or 3/8. Dash sizes go by the 1/16" for example a -4 indicates 1/4", -6 is 3/8, -8 is 1/2" etc. -6 Ac line nut usually takes a 3/4" wrench, -8 usually a 7/8 wrench.

 

Sorry brother, didn't realize you were so far away.

 

I couldn't find a 90 deg #6 fitting with both ends female. You might be able to cut off the end of your liquid line and attach it to your barbed fitting (have to cut off the barbed part) using this compression fitting.. Otherwise you might get an adapter hose made up, but not much room in there.

 

I'd like to thank everyone for all the suggestions.
In the end I went with the compression fitting idea. And WOW! just try to find one of those in Far North Queensland!
Anyway, that's a story in it's self, but luckily I did chase one down.


So I started with these 3 pieces.


After cutting off the hose barb ends, deburring them inside and out. cleaning the pipes up real good with emery. and assembling I ended up with this. A bit longer on one side than necessary, but certainly workable.

Universal condenser connected to factory liquid line.
Now the painfully long wait for more parts.

 

nice! i would not only triple check vacuum when done but also see if it holds compressed air 100 psi plus..overnight before vacuum and charging..
