AC hose question

Just FYI- the flow is the other way, from the dryer to the TXV ( thermostatic expansion valve ). Compressor discharge is out to the condenser, through the liquid line to the filter/dryer, etc.

Yes, if it is in good shape, threads are ok and you can replace the O-rings, by all means reuse it. Post a pic - most are a hose from the dryer to the TXV, but I haven't paid attention to the A body stuff like I do the B body.
