R134A and 134A

[scottsacavsfan]

Is there a difference between 134A for cars and 134A for referidgeration?

[300 Win Mag]

The valve on the jug is usually different. Other than that, NO!

[mdharris68]

I hope not, been using them interchangably lately:) No is the answer.

Why is it $80.00 for a 30 pound jug but 1 dollar for a 1 pound can at the dollar store:o

A refrigerant manufacturer told me that the automotive juice is not tested to the standards of purity and dryness that the refrigeration stuff is. In theory, automotive A/C is much more forgiving of impurities since it doesn't use electric motors and doesn't run at sub-freezing temps.

In reality, I doubt that there would be a problem using the auto version for refrigeration systems. years ago I used automotive R-12 in refrigeration systems with no problems.

i have used the cans from auto zone, in a couple of reach ins a few times in a jam, (on the weekends)

have this funky hookup for my gauges just for that purpose, no callbacks (yet)! on the 1lb cans :)

and the small cans of 134a i got were way more than $1.00 per pound!

The dollar store stuff was made in China without govt regulations up the a... and no quality control cost, and a "slave labor" cost.

Any other questions as to why?

[Poolbreak]

no difference except the valve on the tank and the price.$159.00 at Johnstone and $79.00 at Carquest

Go to Sams Club, I bought several 30lb jugs at $63.00 each. Best price
I have seen.

Be very careful of some marked small cans of R134A, They have oil included in them.

I have seen them on the counters at supply houses last week.

The oil with Refrigerant adds up to a total weight of 1 lb per can.

I got my EPA 609 Certification through MACS [Mobile Air-Conditioning Society] back in the mid 1990’s so I could work on mobile equipment without having to worry about any “gray” area between 608 and 609 certification. This was back when the R-12 phase-out for automotive manufacturers and the R-134A retrofits were in full swing. The MACS study guide mandated separate equipment for each type of refrigerant used, such as gauge manifolds, hoses, recovery and recycle equipment. On-site recycling [not to be confused with Reclaiming] is common in automotive AC service shops and refrigerant that is recovered is routinely run through recycling equipment before being reintroduced back into the system. The MACS study guide also stated that standard commercial grade refrigerant is not of as high purity as automotive OEM/SAE refrigerant and should not be used in automotive or mobile AC and refrigeration systems.
I remember hearing that some guys were trying to use R-414A for retrofits, which is known as “Whirlpool Gas” to small appliance service techs, but apparently problems were abundant. I’m not sure if R-414B [Hot-Shot] was available in those days, but I believe it is now the preferred automotive R-12 substitute. You can even use it in place of R-134A. I don’t know if Hot-Shot’s purity is that high, but it must be close enough, because many shops are using it with excellent results and it must beat the pants off the cost of an R-134A retrofit for an older vehicle. As for the discrepancy in pricing between automotive grade and commercial grade refrigerants, I have no idea what goes on there. I guess it’s like everything else, just a matter of when and where you purchase it.

Sams club it is :D
thanks Ed

I went looking through my old MACS study guide from about 13 years ago, but was unable to find any documentation regarding comparison of the purity of virgin refrigerants, so will have to assume that part of my previous post was based on presumption or misinterpretation and is incorrect.
Apparently, refrigerant “A” is the same as refrigerant “B” and there is no difference between them, other than the manufacturer.

Ummmm, yummy, a tasty meal of Crow!!

There was a patent dispute. R414A has more of something (isobutane???) than R414B. 414B supposedly doesn't return mineral oil as well.

I had to track down the right stuff a year ago. Started calling, everybody had "B" except one supplier. Drove over, paid, looked at the slip, it said 414B. Pitched a fit. He pointed at the jug - which said 414A.

I got to eat some crow too.

Wow!!! now sams club sells refrigerant? whats next??

my favorite 134a fact- it has a Global Warming potential R-22 does not.

[RobY]

my favorite 134a fact- it has a Global Warming potential R-22 does not.

R-22 100 year GWP = 1900
R-134a 100 year GWP = 1300
R-12 100 year GWP = 10,600

R-22 is not controlled in the Kyoto Protocol for climate change because it was already being phased out by the Montreal Protocol for ozone depletion. If there was no Montreal Protocol, then all the CFCs and HCFCs would have been controled under the Kyoto Protocol.

Those are the facts.

JOST ANOTHER HACK WITH a 608 !!!!!!!!!!!!!!

[scottsacavsfan]

JOST ANOTHER HACK WITH a 608 !!!!!!!!!!!!!!

Im sorry you think that :(
Truth is I need it to charge a ice machine that I own
I am learning how to repair ice machines by screwing up my own ice machine
instead of "HACKING" a customers equipment.
I think this is the best approach to adding to my arsonal of skills since I dont have time for or can afford any formal training.
I wish others had the passion I have for learning new equipment and trying to be a well rounded tech rather then settel in just one spot.
