Last year I found that the High Side or compressor discharge hoses were leaking on my 87 X 1/9. Time to do some AC repairs.
For those of you that don't know much about AC systems the X has a good system with very good componets. The evaporator and condensor are made of copper. The hose fittings are all steel. Okay, means nothing, well keep reading. 134a and the oil used in the AC system become corrosive with moisture and attack aluminum. That is why most new systems loose condensors and evaporators. The X copper units will only leak by abuse and if that happens they can be repaired with a bit of copper tubing and a propane torch and solder. The fittings too are reusable. If you take a look at the X AC hoses they have some wild fittings that have custom bends in the fittings. So here is a small sample of how to rebuild a hose and reuse the fittings.
I purchase all my fittings from AC Source, see this Link.

So to reuse the fitting you must first cut off the Ferruel with a dremel tool 180 degrees apart.

Next use a screw driver to split and remove the cut Ferruel.

Replacement Ferruels can be purchased from the AC supplier and use a C clip to hold the Ferruel from slipping off of the fitting. I purchased this Master Cool Cripping set on ebay for $149 plus shipping. You can try and take the fittings to a Hydralic shop, but the tech has to know about barrier hose and that over crimping it will puncture the nylon inner hose and you will have a new leaking hose.

Use a 3/4" wrench to hand tighten the cripping dies.

Finished hose. New Barrier hose with old fittings. Also I will add that the fittings could be changed to use a new dryer canister to fit the X's front trunk.

This is a picture of the Ferruels that come with C clips that snap into the groove of the old fitting.

More to come as I progress.
4 years ago I did my son's 85 Mazda RX7, he seems to be the only one driving a First Gen RX7 in the summer heat with the windows up.
