Hey guys
  Has any one ever used a product called Hot Shot R 414  it is a r12 r500 r 134a replacement all in one and can be used with cap tube systems and in compatiable with most oils .I wonder how it works in the vintage systems  :happydrinkers:

A friend of mine in Alabama used it and said it gummed up the system in his machine but that's the only thing I have heard about it.

So      what is the best Replacement Gas to use  for a  R12 system??

I use 12 in a system that used 12 in the first place, otherwise, Eric at Global compressors will have the most knowledgeable answers.  His ad is on this website and he is always glad to answer questions, he is really nice intelligent person.

I use Hotshot on 95% of my service calls on both R12 and even R134a systems, it works very well & It has a temperature vs pressure rate thats dead on to R12, I've never had any compatabilty issues with Mineral oil , or modern system oils. I've never had to add any additives to early mineral oil systems, but you must recover all of the old R12 & pull a good deep vacuum to remove any water vapor & residual R12 from the mineral oil. ( just as you should with any refrigerant) I have in the past added some poly-oil to mineral oil based compressors that seem to be pulling too much run current, to just help ease the friction on an older worn system, but it has nothing to due with the use of Hot-shot.

In a capillary tube system & most expansion valve systems it works just fine for high & medium temp units, you just have to put it in at the recomended percentage of the original charge (typically 80%, )

In a system that uses a flooded evaporator system ( such as an automotive AC system) it is not recomended due to the fact that it is a blended mix. & different components will evaporate off at their own boilling points, which causes pressure surges in the system which effect the bypass / feedback circut in some expansion/control valves,

Hot shots' web page has lots of good facts regarding this & other replacement refrigerants they offer. so be informed & google it up!  :biggrin:

Hot shot is also sold under the name Freeze 12 for automotive use  comes in 12 oz cans .I charged a uss-96 today with it .I changed the drier and replaced the drain hot gas loop with some new copper and pulled a six hour vacum .System runs great so far .Thanks for the input guys    :hopefull:

Good deal then! 

but.... FYI; Johnsens' makes Freeze-12,   ICOR makes Hot Shot/R414a

You can find Freeze 12 at PEP-Boys auto stores, but you have to ask for it, as they keep it on the back shelf. & it's all over the web & Ebay too.

You can't purchase Hot Shot unless you are EPA certified. (legally, anyway)

Has anyone ever use R404A?

DONT 404A is a higher pressure refrigerant that is mainly used in commercial freezers, unless you're looking to blow the snot out of your compressor DONT use it in an R12 system.  :wow:

Old Thread but it gets a lot of traffic reviews...so

I Just saw this on a review...Hot-shot is NOT the same refrigerant as Freeze12 like Apples & Oranges.
