Bob, 

actually there are rubber hoses out there that are more capable of handling 
R-134a. if you go to a place that specializes in pressurized lines and 
hydraulics, they can sell you some stock hose that will hold 134a. 

about two months ago i had my system vacuumed and the oil replaced with ester 
100, and then charged with R-134A. i had a minor leak in my flexible lines 
but i had it repaired at a hydraulic shop. i didn't do any of the 'expert' 
stuff either, and my A/C blows so cold i have to turn it down after it's been 
running for about 30 minutes or else my hands go numb!!!!

the place i did it at said the real trick is to vacuum the system for a long 
time, on the order of 2 hours. you really have to get all the moisture out 
for the system to work well. these guys have been doing it this way for a 
long time and haven't had any problems, and i haven't had any problems yet 
either........ but i'm just crossing my fingers!
