How bad are 12oz cans of 134

tomibriggs on Tue July 14, 2009 5:30 PM User is offline

Year: 1996
Make: Toyota
Model: Corolla
Engine Size: 1.8L
Refrigerant Type: 134
Country of Origin: United States

I may have access to a vacuum pump & manifold guages but not for large quantities of refrigerants & oil like those that come in cylinders. Is it really that bad to use the ones that come in 12oz cans? Is there an acceptable way of using them to properly charge my system?

Thanks!

Most DIY'ers have to use cans, just make sure they are cans of virgin R134a, with NO additives and you'll be fine, bleed the air out of the charging hose when you switch cans to prevent air from getting into the system...

Just as soon spend the 88 bucks, now and buy a 30# cylinder, cans are a PITA with all that purging and trying to get a can tap that doesn't leak out, 30# cylinders have a half way decent valve. Then you need a microscope when buying cans to make sure they didn't add any junk with all of that fine print.

Sure wish I purchased several containers of R-12 when they were selling it for 25 bucks for a 30# cylinder, just said I have plenty and was totally unaware that it was being phased out, we didn't have an internet back then. Can say this about refrigerant, the price of it nevers goes down, and may even skyrocket for R-134a if the keep on playing around with it. What is the price of a 12 oz. can anyway? Seems to be more than twice the price if not three times the price per pound. Just use about 10# from the cylinder, and you will break even. And as crappy as the AC systems are today, using that won't be a problem.

And I don't care what anybody says, purging is a guess and have to do a lot of that with cans.

It's not bad using cans i don't have a problem with air i leave the hose on the can tap close the valve then just switch cans to and from the can tap never need to bleed hoses because i don't loose anything still a charge in the hose,it would have to leak by the valve and the check valve on the yellow hose.


would like to get a 30# tho what are you guy's seeing for the cheapest place to get a 30#?? The cheapest place i found is Advance Auto Parts.

NickD....$88 for 30lb of R134a? Least expensive I've come across is $100 for an empty can. Full 30lb is about $130. Are you buying for $88? Lots of 40 will go for about $90.... 12oz cans are $4.75 here.

At 2, I went home with a 10. At 10 I woke up with a 2 !!

Sams club has 30# R134a for $80. They also have twelve 12 oz cans for $40 which makes them like $3.33 each. However walmart sells the same cans individually for $6.77 and they are pure R134a, no oil, no sealer, no booster, no nothing. So thats what i have. I bought a case of 12 cans. I need to get a 30# container, but not sure what kind of scale to get to use it with.

Never thought about Sams. I checked our local Sams. $82.12(30lb) & $39.64(12 cans). Don't have to be a member, just pay 10% over the listed price.

I got a special 100 day summer pass to sams for $15. It has more than paid for itself on all the things ive gotten. I will be getting the $40 1 year membership as soon as this one expires.

I got a 30# jug recently for $89 plus tax, about $96 total. That was at a local CarQuest parts store, for DuPont SUVA.

My 30# cylinder weighed about 36 lbs before I cracked the valve open. That's going from memory, but I did write down the weight on the box for future reference.

$100 for an empty can sounds like a recovery/recycling tank. Those are much heavier (and obviously much more expensive) tanks than the refrigerant comes in. The supply cylinder only has one tap (you invert it to get liquid) and has a check valve to prevent refilling.

dumb question, but how many oz's, like the cans are sold in, make up a pound?



TRB on Thu July 16, 2009 6:35 PM User is offlineView users profile

16 ounces in a pound. There are supposed to be 12 ounces in the little cans of refrigerant. How much faith you put into that amount being in there is a judgment call. We have used 30 pounders for as longer as I can remember except for R12.

I weigh before and after each can so i know how much 134 is gone in and usually...there's 11.5 to 11.8-12 oz in each can. So very very close to 12 ozs.

They need to be weighed,one cannot just assume there's 12 ozs in each,you'll be off your charge amount if not weighed.
