AC Fittings Size

Hey guys,

Im about to convert my entire AC over to a Sanden 508 and Universal Parallel flow condensor, so I will have to make some custom lines. But I cannot find ANY information on the sizes of the stock fittings I will need to connect to:

Compressor to Condensor
Condensor to High side hardline fittings
Accumulator to compressor fitting

Re: AC Fittings Size

The fittings are ... the size that they are. They're not "universal", like, you can look them up at Summit or something. Best thing to do will be, use a wizz wheel and cut the crimp ferrules off of your stock lines; and re-use the sections closest to the evap. Make, or have made, new metal sections that fit your new compressor and condenser.

Compressor to Condensor
Neither end of that line will be stock. Check the info that came with your new compressor and new condenser. Nobody out here is going to know that.

A useful strategy might be, go to the junkyard and find a car with the same kind of compressor, and gank the line manifold off of it. That will get you everything you need except at the condenser ends. Then use "barrier" hose to connect that to the stock pieces that you will re-use, as described above.

Re: AC Fittings Size

Thanks!

I know the fitting size on the compressor and the condensor. Thats not an isuse. The issue is tying into the two places with the old parts, like at the accumulator/suction line joint and the liquid line/condenser joint.

I just gathered that the accumulator is a #12 O-ring so I will see if that fits.

Im trying to replace it all with ez-clip if I can. So I really am trying to find the size used.

Re: AC Fittings Size

Go to Sanden.com.


Hover your cursor over the products tab, and select Piston Compessors.


At the bottom of the list are the SD5 series compressors. They show a 509. Assuming this is like your 508, go to this .pdf.

Page 6 shows fitting sizes.


Or you can contact Sanden support from the home page.
