I want adapters to connect R12 gauges to R134 system
Do these exist? I have a set of r12 gauges I got for free from a relative. They worked great on my 1987 T-Type. Can I get some sort of adapter to connect onto the new style fittings?

Since mixing different types of freon is very bad, the fittings on the guage sets are different. If you want a set of R12 guages you need to buy them separate - about $60...

This should have the title changed to "Bum Scoop" Where do people get this crap? Every refregeration shop uses the same gage sets for all freon. The only difference is what scale is marked on the gages, and most use a temp/pressure chart anyway to be accurate. It may be r-12, r-22, r-134, or something else. Anyone that know what he is doing purges the lines before working on an AC system anyway. You can even use these gages for propane, or some of the other refrigerents. (Not amonina).
Go to any NAPA dealer and for a reasonable price they have a fitting kit. I don't recall what it cost but it is less than $20, maybe even about $10. The kit includes the quick disconnect r134a fittings used on later model GM's and several other types. You can also buy replacement hoses. At the NAPA store that I use, you have to ask for the fitting kit, as it isn't displayed, but kept in the back with other AC supplies such as bulk freon, vacumn pumps etc.

Here is another question, in the US (I am in Ontario) can anyone go buy Freon (R134a). Here in Ontario I need a certificate to do so, its a real pain that I cannot just top off a system. The certificate shows that someone has been trained in refrigeration and knows not to vent a system into the air for environmental reasons.

EDIT : In the U.S. you have to be certified to buy R12 but not R134a.

I got a manifold set that was for both R-12 and R-134 from Matco. They used different hoses but the same gauge.
Freon went from $79 for a 30lb cylinder up to $350 plus now. Anybody can by 134a.
Freon does have a leak out rate. I learned this a while back in school. I think its like a pound for 6-7 years. Im not saying every vehicle will leak out freon, but it can happen.

How about someone start a Poll to add a new topic on A/C systems?

One thing for anyone replacing hoses or for changing a r-12 system to r-134a. R-134a requires "barrier" type hoses. It will leak through many of the regular type AC hoses that were used with some r-12 systems, especially those used on the cheaper cars/trucks.

All the information here has been useful.
OK - so it is now critical that this board set up a separate topic for air conditioning issues.
Lets do this NOW!
Thanks....
