I'm retrofitting a universal drier on my RX-7 because the correct drier can no longer be bought. This requires me to use some custom hoses, and the hose ends have steel nuts. I can't get metric hose ends with aluminum nuts. These steel nuts will be threading onto the factory aluminum fittings. Mazda used aluminum nuts, so there was no issue with dissimilar metal corrosion.
My question is: What sort of anti-seize compound is appropriate for use on these fittings? If it was a spark plug, I'd use good 'ol copper based anti-seize....but this ain't a spark plug.
I really don't want these things to seize on there years down the road and ruin some very difficult to obtain factory parts (condenser and liquid line).

This link will get you where you need to look: Loctite and there are other links on that page. Probably the Zinc stuff.
Your using steel and aluminum just like a spark plug in a aluminum head so whatever you'd use there, use it here. You won't find the Loctite Zinc product in a small amount anyway.

Try mcmaster.com and see if they have the nut you need in aluminum.
Hi 94ZR-7; Like TRB says--check this site, go to main page, scroll down to "Nylog". I use it just as it says-For threaded fittings and o-rings, never hardens,etc. Total compatibility with A\C, great stuff!!
