Converting factory AC to use R134a - The 1947 - Present Chevrolet & GMC Truck Message Board Network

RedRoad · 08-08-2015, 07:37 PM

Im starting to collect parts for my K20 Suburban A/C and have to get a large amount of hose to run to the rear unit. I was wondering if anyone has just cut off the fittings for the compressor/condenser/POA from the old lines and just used hose clamps instead? If I do order new hoses I hate to have to cut them in half to add the T fitting that just uses hose clamps anyway.

Is there a conversion schrader valve kit I need to install to the old muffler and valve to use 134?
