Can someone tell me what size AC lines these are?

[jumpsoffrock]

The pictures are upright when viewed on my PC and phone.

The more I read and deeper I dig the more confused I make myself, I'm trying to piece together an AC system and would like to know what these line sizes are.

The larger size goes to the POA and takes a 1⅛" wrench on the female nut.

[Steeveedee]

Adding tube thickness, I'd say 1/2" and 3/4" tube.

No i mean in terms of AC line sizes, is it #12, 10, 8, 6?

The factory manifold/hose is #12 for suction and #8 for discharge. This corresponds to the hardline sizes Steeveedee noted. Something like the Sanden typically has #10 and #8 fittings. You can find fittings that are say #12 hose and #10 at the hard connection. I am using one on my suction line to Sanden compressor.

[jumpsoffrock]

Wow so they totally skipped using #10 line on the factory setup?

Yes I'm trying to hook it to a sanden and am realizing that I'll need a funky "12 female to 10 hose" coupler. Only $16 but it's still niche.

Thank you guys very much.

#12 hose (crimp) to #10 oring connection is what I think you mean. Cold Hose is where I found them.

You can buy those lines already made up thru LMC. I did with perfect fit and zero problems.

The internet is your best friend.

So this is incorrect? https://www.ebay.com/itm/31557036158...2dKMY8VA&gQT=1

If I have my ducks in a row, I am tring to go from the MALE evaporator line, to the MALE Sanden #10 nipple on the compressor.
So I need a FEMALE threaded fitting type thingy, going to a #10 hose crimp thing, then #10 barrier hose goes to a normal #10 crimp/FEMALE fitting which threads onto the compressor nipple.

Thank you sheepdip, I try and keep stories out of the posts if I'm really trying to get down to business.

The vehicle is a '67 Caddy and there aren't such things as "aftermarket new parts" for such a car--but the lines are the "same" size as these trucks.

I'm trying to figure out what "number size" correlates to what I see on the caddy, so I used an old set from one of our trucks to correlate with.




One thing that makes swapping any old car to a Sanden kinda weird is that every dude/dudette out there chose to use a different Sanden because Sanden made 300,000 variants of the same thing.

So even though there are THOUSANDS of threads of info, and many different "kits" to look at, they are all a little different in exactly how they make the lines retrofit to the old cars AC system. I really wish I had observed that before I bought the compressor. But I bought it years ago for a different project and it can't be returned so I'm trying to make it work.


Thank you all very much again. I know people try to steer folks away from DIY AC for several reasons.....but.....over the span of 10 years I've bought various AC parts to retrofit FOUR different vehicles with modern AC and every time "life" happens I give up and move on.

Well this time for this cady I'm determined to succeed. I know I can DIY this AC install, I just gotta try and learn.
I don't need a show-perfect system that is perfect, It's just gotta hold pressure.

The link provided is just fittings from a manufacturer? Was expecting a link to some hoses? LMC is last in my choice of vendors. But great it worked for you. I have a crimper and can make my own hoses, clock them as I please. Not really expensive for the tool.

Your link is does not work and the item # in it comes up as nothing. So I have have no idea what you want to use. I have a crimper. Just cut incorrect fitting off and install the fitting I need on the hose.

Have experienced the same problem with ebay links myself lately. Not sure if it is ebay or the cloudlink software now used on the site. Found it with your item number. If you are using a #10 hose and using this where the stock u-bend fitting at the POA would go. If line can be routed it should work. I used the stock u-bend and #12 hose and changed fitting at compressor. As you mentioned, many ways to go about the conversion. Hope for the best on your conversion! Give me a PM. Where are you in CA?

Here is what I used for my conversion to sandan. https://www.amazon.com/dp/B07RX884P3...fed_asin_title

Thanks for posting! The first link to the U-bend fitting is really helpful in a conversion with a Sanden compressor on these trucks. I already have a stock type hose manifold in hand with #12 hose I was trying to make it work with a compatible Sanden compressor head. Not going to work out so I got the #12 hose to #10 oring fitting at compressor. No worries as not a big loss. As mentioned previously. Several ways to go about this.
