     The type of refrigerant characteristics affect what's needed in the 

     hose.  For example I've been told the new R134A permeates the old 

     hoses, so a new type hose must be used that has an inner skin that 

     cannot be punctured by hose barb fittings.  I've heard there are some 

     drop in replacement refrigerants that aren't officially sanctioned by 

     the automotive engineers (SAE), which work well.  Most of the 

     replacement refrigerants I've heard of are a blend of gases, which 

     means the system must be charged only from the liquid state (very 

     carefully to avoid busting the compressor).  Reason is, a blend's 

     gases are not homogenous, so the lighter ones would go in first which 

     would mess up the chargé in your system.
     

     I haven't heard of fr12, however.  Is it a blend?

------------------------------
    My  86 westy has some a/c hoses that need replaced and I have been
trying to locate some bulk a/c hoses. I received a quote of $3.75 for 1/2

inch and $4.50 for 5/8 inch per  foot of hose.   This place will install the
factory like hose clamps included at  that price.  These hoses will handle
all the old and latest refrigerants.  This hose place normally does
hydraulic and high pressure air for farmers, coal mines and other industrial
applications.  I ask  the list if this seems like an OK price?
     I am considering using fr12 after I finish the hose job. It is quite a
lot cheaper than r12 and according to Pennzoil dealer will cool as well as
r12. Any comments  on fr12  are encouraged and welcome.
