R-12 can be purchased at a VERY FEW refrigeration supply houses (old stock, not yet depleted) but you need EPA certification and the price is ASTRONOMICAL. A better solution would be to use R-414B, or "hot shot", as it is a drop in replacement for R-12, and actually runs a little lower pressure for the same cooling. Good for compressor longevity. But you still need the EPA cert... DON'T just drop in 134a as the expansion valve does not have sufficient adjustment range to meter it correctly and it will eat the rubber seals in the system over time. Best bet? Buy a local refrigeration dude a cold one, crack your wallet and tell him to hook you up with some "hotshot". It works.------------------------------------------------------------------------------------------------
You don't need R12 for anything anymore. The last cars to use it were about 1994. If you are driving something that old, I would just put in R134. Contrary to popular belief, nothing bad will happen, it just won't put out as much cool air.
In reference to the first answer, you cannot just charge your system with R-134a, the O-rings in the system are designed to withhold the chlorine in the R-12. the hydrogen in R-134a eats away in at the seals in those systems. Retrofitting is the best way to get around an empty R-12 system. You have to get a new accumulator for an orifice system or a receiver/dryer for a thermo expansion valve (TXV) system. replace any sources of leaks. add PAG oil for lubrication of the O-rings and the compressor, you should have 2 oz. of oil for every component in the system. example the components in an orifice system; compressor, condenser, orifice, evaporator, accumulator, and lines. 16 oz of oil. you should fill your retrofitted system with only 80% of the manufacture's spec for R-12. example: In a 3 pound system, fill your car with 2.4 pounds of refrigerant. this ensures generically the coldest your new R-134a system will blow. If your R-12 system works perfectly fine and is just a pound short of a full charge, ask a local professional if they could track some down for you, it's going to be more expensive but there's a lot less work to be had.AnswerDue to federal law, only licenced repair shops can possess r-12. Might as well go to the pros for a recharge. I got lucky and found a few cans in a friend's basement. John In Montana AnswerGo to Walmart and spend 33.00 for a kit. Have a vacuum pulled on your system and changge the high side fitting with the correct one in your kit. Put the new can of refrigerant oil in and the freon while running your a/c on max. Stop adding freon when the compressor kicks on a 25 and kicks out at 40. There is a gauge on the filler apparatus that comes in the kit. It is a very simple procedure. AnswerThe kit mentioned will not have R-12. It will have R-134a, or worse, an "R-12 substitute." If your system is designed for R-12, it may not work well with R-134a, and the R-12-compatible oil in it will not mix with the R-134a. There is a possibility of damaging the system. Using an "R-12 substitute" often has an even greater risk of causing damage. If you want a safe, reliable repair, have a competent shop service the system with R-12 or do a proper, complete conversion to R-1343a for you. AnswerYou can get cans in Mexico AnswerE-bay AnswerYou can't buy R12 anymore unless you go to a professional. The best thing to do is get the car retrofitted. AnswerIt is against the law to buy or sell R-12 unless you are a qualified mechanic.Then scarcity of R-12 has driven the price so high,it is better to get retrofitted.The price you would pay from the black market isn't worth it. AnswerEbay...the catch is you have to email the seller certifying you are buying the R12 for your certified auto tech to insyall!
Got mine from the trunk of some guys car at a garage sale....1 lb R-12 originally $1.29 at K-Mart ...now a bargain of three cans for $45!!! Works great for my 1989 BMW...needs about 1/2 a can each year...to keep er freezing cold...figure I have enough to finish er off!! :0)ANSWER
If you are not certified to handle R 12 I recommend you don't, because the fines can be severe, they claim the emissions of refridgerant into the atmosphere is adding to the damage of the ozone layers if you have an older vehicle and insist on using the R 12 freon then take it to a certified A/C shop the repair/charge will be costly.
If you want the cheaper route to go with(R134A) then go the alternate route and have a certified shop discharge your system by means of an evacuation pump to remove any and all contaminants if the system was empty, you should replace the receiver drier when doing this type of work and after that is done refill the system with R 134a refridgerant, have the system leak tetsed and if all is good you are done!!
Ebay in small single lb cans. No license required for Ebay small purchases
BUY A RETROFIT KIT AND SOME R134A. ITS CHEAPER< AND ITS LEGAL!
DO NOT USE Hot Shot for any refrigeration unit whether automotive, home, or commercial. The unit will never work well again. There is a great R-12 alternative that does work as well as R-12 in an R-12 system and has been proven over years of use in cars and commercial refrigeration units by many contractors. you will not have to worry about seals, O-rings, valves, or expansion devices needing to be changed. R-420a (previously RB276) is the absolute closest thing to R-12 but still needs certification to purchase or handle.
Also do not use any refrigerant that says it is "environmentally safe". It contains hydrocarbons (HC's) which are flammable and will ruin the internal parts do to lowering the viscosity of the mineral oils. Find a refrigeration contractor that uses R-420a in older refrigeration equipment and ice machines. Google R-420a or RB276 for more information.
I am an HVAC refrigeration contractor in SC that discovered R-420a over 12 years ago and am still using it in refrigeration and autos with great success. R-134a,as stated before will not work well in an R-12 system for many reasons including incompatibilities of oils. R-12 can still be purchased by certified contractors/mechanics from sources like e-bay.
A monologue is a long, uninterrupted speech in a drama that is spoken by a single character It is often the character’s internal thoughts, and feelings. but also can be addressed to one or more characters, or the audience. A monologue is one kind of dramatic speech, which can define conflict and move the action of a story forward.
Example: The following is the beginning of a famous monologue from Shakespeare’s play Julius Caesar. Antony is speaking at Caesar’s funeral. Caesar, the ruler of Rome, has been killed by his political opponents.
Antony: Friends, Romans, countrymen, lend me your ears;
I come to bury Caesar, not to praise him.
The evil that men do lives after them;
The good is oft interred with their bones;
So let it be with Caesar.
A. DIRECTIONS: Answer the questions below.
1. To whom is Antony speaking?
It is from his monologue in the Shakespearean play Julius Caesar.
He is speaking to a group of Romans.
2. What is Antony’s main point in this part of the monologue?
first person point of view
3. What details might Antony include in his monologue?
A monologue is a speech made by one person, either in the presence or absence of others. Julius Caesar is a play by William Shakespeare. "Julius Caesar Monologue" is a long speech made by someone in that play. Mark Antony has a long monologue in the play and so does Brutus.
B. DIRECTIONS: Describe a character and situation that would be a good basis for a monologue. Use something that you have read or seen before.
You cAnt sorry
They should never be mixed.
Was built with R12Was built with R12
The chemical formula of Freon 12 is CCl2F2.
1993-95 for most.
R134a Freon is an oxymoron, Freon is R12 but the answer is yes, a subtle 'sweetish' odor
2 pounds of r134a. Not r12.
It came with R12 Freon. As R12 is cost prohibitive, have the unit converted to R134a refrigerant or a similar substitute.
None, the refrigerant is R134a not Freon which is R12.
Contains no (R12) Freon. Freon was banned in 1996.
There is only one Freon, and that is R12. R12 Freon came installed in your 1991 Chevy. It may or may not have been changed over to R134 Refrigerant. If not change it over, as the cost of R12 is unbelievably high an is no longer in production.
r12 or 134a
It originally came with Freon (R12). Unless it has been converted then it will still contains R12. I suggest you have it converted to R134a, as Freon is so very expensive and hard to find.
There is one valve that is used to add refrigrant. But you had better not add Freon. Freon is R12 and your vehicle's A/C system does not have Freon (R12) as a refrigrant. More than likely it uses R134a.
It was built with R12, can be coverted to R134aIt was built with R12, can be coverted to R134a
It contains no R12 Freon. Freon has not been used for years.
