93 Mana A/C fittings
Hey all I am in the middle of A V-mount, and have tried many different routes and lines, bending, twisting, and ultimately just destroying the factory lines, it's hard enough to try and find the Oem A/C lines for a decent price, but now I'd just like to go the custom route. Does anyone know the sizes for the A/C fittings? A few seem to be the same, an honestly It looks like there might just be two.
I am mainly working on the condenser to drier side of the A/C system. I have spent a lot of time making the V-Mount perfect and I don't want to sacrifice my A/C especially since I incorporated it into my design.
Please let me know if you have any suggestions, I am also ok with ditching the factory drier to make things easier, so technically as long as I find the two sizes for the condenser and the one size for the low pressure line crossing from the evap to drier with the low pressure switch I'll be good.
I have done quit a bit of searching. Hopefully someone can help me out!
Thanks

I don't recall the sizes off the top of my head, but I do remember that the Mana system uses Metric sizes (as opposed to the Denso system, which uses common AN- sizes).
When I did my v mount with a Mana system several years ago, it seems to me that I had to buy some of the [less common] metric ends (off of ebay, of all places) and splice them in.
I haven't seen your setup, but be sure the liquid line exits the condenser at its lowest point for best performance.
Hope this helps.

That you for the advice, I believe I have the routing figured out, however I am going to need the sizes to go any further, you've narrowed it down a little bit more for me. Thank you, here is a pic of the setup

I found some good info here so far,
The liquid outlet (small) from the condenser on a MANA system is M16x1.5 I have no idea what the inlet size is. All the aftermarket universal condensers you're gonna find will be #6 and #8 fittings. (Although I got one for my REPU that was #6 and #? and required an adapter to get to #8. LOL) You can take your existing compressor discharge hose to a hydraulics shop and have it re-made with the factory section of aluminum on the compressor end, and a standard #8 fitting on the condenser end. I would suggest you go to a universal drier since the MANA units are NLA, so you'd just have a #6-on-both-ends hose from universal condenser to drier. Then you'd need a #6/M16x1.5 hose to go from drier to the stock hard line that runs across the front of the car, although you may be totally screwed here since the aluminum tubing that Mazda used is smaller than the standard #6 tubing. How's that for an update?

Hey, after some thought, I seem to remember the larger inlet fitting being M20 x 1.5--although I'm not 100% sure on that; tubing may be 11 or 12mm.
Do you happen to have a pair of calipers available to you? You could measure the thread OD of the condensor inlet tube and fitting to confirm.

Funny you mentioned that, I was playing around with my straight rule and was trying to get that answer myself... My problem is I cannot get an accurate measurement, mainly because I can't seem to reference it correctly. I'll try and find my calipers I'm in the middle of moving so it may be a journey lol

One other thing worth mentioning is that I've successfully used industrial steel compression fittings (available through McMaster-Carr and others) on refer lines and they have proved to hold up well. I know I used one to splice the FD compressor discharge line at some point. And they are very helpful if one needs to rotate one end of a line [relative to its origin] along its axis or to simply join lines.

Check out halfspecs posts on A/C lines. Might be some useful info in there:

Thanks for the info, It has great information, but not for the Mana setup other than the larger evap fitting is m22x1.5 and the smaller is m16x1.5
Just a note from that: the fitting required to go into the m16x1.5 requires a 7mm hose fitting not the #6 which is typically offered

So in my attempts at finding the sizes I need I managed to find a local guy that makes A/C hoses.
Now Being the Diy kinda guy this pained me to do. I had them make up lines using the original ends.
So long story short I've moved a few things around. One of the biggest changes were getting them to weld on #8 barbs and #6 barbs in place of trying to get the correct metric hose fittings, ( which are nearly impossible) so all things considered I would recommend this route to anyone who has the ability.
I relocated the larger condenser line to shorten the amount of hose required. I'm now faced with trying to get the hose low enough so that It doesn't hit the compressor.
