R-12 question.
a freind talked me into going to a yard sale with a lot of tools earlier today. well, i got a full size drill press, a set of R-12 gauges and 2 full in sealed boxes tanks and 1 1/2 full tank of dupont R-12, and 2 full in sealed boxes tanks of 134-A for $125. i have been doing 134-A for 10 years, but never did R-12. are the pressure readings the same as the 134-A? 40-45 lbs low side and 150-160 high side??

thanks for the conformation on the pressures.
i knew as soon as i saw the prices things were going for, that there would not be much left. the ac stuff was in the shed in the far back yard, i guess everyone else thought it was the neighbors .when i saw all of that in there it was a no-brainer that it was going home with me. the $25 drill press was an added bonus, after the guy that was looking at it in the cellar realized it would not fit in the trunk of his car. i tossed the keys to the crown vic to my partner, and without a word he was gone. 5 minutes later, he pulled up in my 79 F250. we loaded the drill press, gauges, and freon tanks for me, and the 4 snap on tool box roller cabinets he bought for $20, and the $50, 120 gallon tank, 10 hp 4 piston pump, 220 3 phase air compressor.
i got over $1,500 worth of R-12 and R-134 Freon for $100,
and a $500 drill press for $25
for $70 dollars, roger got 4 tool boxes worth around $1,600 new,
and an air compressor that has to be worth at least $4,000.

every 134 system i have ever repaired or charged has run around 3 to 1. 40-45 low, and 150-160 high. and the warmest system output i have ever had was 42º on a 95º day. my crown vic on max air has an induct temp variable of 29º to 38º
my personal mack truck is the same. average induct temp is rite around 36º.

R12 runs almost the same as 134 the 134 runns at a slightly higher about half a pound I have been doing this for years I prefer 12 to 134 another really good gas that mixs with 12 and 134 is 414b that way you don't have to keep several takes on hand all the time next time you buy pick a can of 414b up it works really nice

can't tell you anything about that. i have never converted a system. pre 93 has gotten the R-12 done at the shop down the highway a piece, and after 93 gets 134a done in the garage.

well the drop in gas for r-12 is 409a that is what you should really use but the cost is so high that I use 414 in almost everything that I do. Sams Club has 134 on sale right now for $195.00 while it lasts I picked up 12 30lb cans of it. Thats cheaper than my wholesaler can get it right now

sorry njf, i was not referring to your post with the conversion comment, rather to snomans post. i actually did not even see yours till just now.
i have heard about the 414b gas before, but 75 lbs of 12, and 60 lbs of 134 for $100 was a hard deal to pass on.
i figure i have enough freon in stock now to last me for life, and also leave some for the kids, or whoever gets all my crap after i am gone.

414 does work well with r12 but it works better with 134 with the price of 409a I would rather use the 414b as 4091 is well over 300.00 for a 30lb can and 414 runs just a little over 200.00 for a 30lb can
