AC Compressor Muffler Hose Reapair?
Does anyone know if you can repair the AC muffler hose on our units or do you have to bite the bullet and buy new for $200? My hoses are cracked but the Al metal fittings are fine. If they can be "re-crimped" then its not an issue. If not then I know I can not re-use. Was thinking of AC shops having this ability????
Looks like this:

i think it may be repairable ,at a hydraulic shop. the old crimps will need to be cut off so it will never look original if that is important to you.
i know from experience that hose is very difficult to change ,you only want to do it once.while you are into your system that far adjust your poa valve (if you are running 134)to 26 psi.if you haven't already.

A hydraulic shop can replace the hose and use the old connectors. The hose they use obviously will not read GM or whatever the original markings were.

Automotive AC shops and other places can make replacement hoses for you. I had a hose blow on my 74. Took the bad to my NAPA guy and he made a replacement.

its probably more agravation than its worth getting the old one repaired,getting one made or buying a replacement from one of the vendors should not be a whole lot more expensive than the repair of your split hose. if you do go the repair route get the fittings indexed correctly or you will never get it to fit,on my big block there is NO room for error.

You can take it to any automotive A/C shop.
They have the proper ferrules to crimp your original hardware that look very close to the original crimps.
Prices vary greatly, so shop around.

unless i am missing something,on the original hose the "crimp" was part of the fitting ,not a seperate sleeve.the original crimped section would have to be cut off and replaced with a new sleeve. not too sure how that would look ( if you care about that sort of thing). but i'm sure it would be a lot cheaper than a new one.

dtamustang et all where is the POA valve? My system was converted over to 134 but I am not sure what was done and if this was part of it. Can you explain this in more detail? My engine is OUT and now is the time as I have ample room to access all the hoses and valves etc.

i am no expert by any stretch of the imagination,the poa valve is the what the other end of the suction hose hooks to(non compressor end)some people elect to eliminate the poa with a kit vendors sell.it turns the system into a cycling system as oposed to a system that runs the compressor constantly. after exhaustive research (mostly on the auto ac forum) the guys that seem to really know their stuff say its not the best way to go.from what i have learned the key to getting a system converted to 134 to cool as well (some claim better) is the proper adjustment of the poa valve.
i did the adjustment on mine and i have vent temps of about 45 degrees on a 90 degree plus day.
if i tried to explain how to test an adjust the poa i would be making a fool of myself and confusing anyone who read this.....google poa valve testing and adjusting.
if i can figure out how to post a link i'll put it up here
if i have said anything that is not correct ,the folks who really know their a/c systems feel free to set me straight
