My truck is an oven if the temp even looks toward the neighborhood of 75 degrees.
I got one of those car a/c for dummies kits, last summer.
Decided to actually go through with recharging the system, this year.
Got the hose attached to the can, then went to attach it to the ac in the truck. (Just following the steps on the can.)
Turns out it will NOT attach to my truck.
My truck has the old r-12 system on it. The a/c for dummies kits are set upfor r-13. Which is of course, the refrigerant they are using…
I heard something in passingabout somesortof retrofit kit I can use to convert my r-12 system to an r-13 system.
but I have not been able to find even an example of one.
Does anyone know of this kit ? Better yet,where I can get one ?
My truck is a 93 s-15 Jimmy 4wd.
I hope I can find a kit that will work with this a/c for dummies setup. Because otherwise, the 40 dollars spent on this kit is wasted. I can’t take that hose back off. The can is pierced.

Might have better luck looking for an R-134A conversion kit. Don't know much about it but my BIL had his old Caddy converted and was only 200 bucks or so.....
Can't you still get R-12 if you have a license?
And this from wiki...
Be extremely cautious about converting your old R-12 system to R-134a. The R-134a conversion kits sold at Auto Parts stores and even WalMart, are called "Black Death Kits" by some AC repairmen. Frequently, the new R-134a refrigerant will not circulate the R-12 oil and you will burn up your compressor. The R-12 mineral oil has chlorine contaminants that will destroy the R-134a PAG or POE special oil. The only way to reliably convert from R-12 to R-134a is to remove the compressor and flush out all the old oil with the new type of oil; then replace the old Receiver-Dryer or Accumulator with a new one; then flush out all the lines, the evaporator, and the condensor with special cleaner then vacuum to a steady vacuum; and finally charge with 70-80%, (by weight) of the original R-12 weight, with R-134a; and expect poorer cooling ability. It is much easier to keep the old R-12 system running with R-12 that is readily available via ebay.
think propane
Kinda hoped you'd reply.Is this the same as the quick disconnect type propane fitting ?If so, it'll still mean finding a couple of specialty fittings, before I can connect this to my truck's fitting....Max: Are you thinking what I'm thinking, Chief ?Chief: I don't know, were you thinking, "holy sh#t, holy sh#t, a swordfish almost went through my head" ?..You are always welcome at Quittintime
No, there are R12 replacement gasses that are based on propane. I used one and it worked great, but I didn't fill it properly (didn't evacuate the system first) and I eventually blew a compressor.

Look, just send me to my drawer. This whole talking-to-you thing is like double punishment.
Luka,Propane will work instead of r12 but leaks aren't pretty!Look for some Freeze 12 as it is a cheap direct replacement for r12.KK
You can still buy R-12. Plenty of it on eBay.
If your system works, just top it off. It's cheaper- especially if you can DIY it.
The conversions don't perform so well because the R12 evaporators and condensers don't have the surface area to work well with R-134A. First generation OEM systems also suffered.
