I just finished taking inventory of my nos parts and there are a few that I can't ID. If you can and need them they are yours for the shipping charges. Here is the first, it is a brake line I think but it is copper and has some different looking fittings. After this is gone I'll do some more.
Looks more like a p.s. or a/c hose....my old aerostar used one similar for the pressure side of the power steering.
Yes I agree with Rocky. In fact I would say A/C almost for sure, and looks to have -6 o-ring fittings. I'm thinking condenser to dryer.
Don't know what you call it but my mom had one in the bathroom with a hot water bottle hooked to it. I'll ask........OLDBEET
