Is 12a the same as R12?

RED TEK 12a has a lower density (but higher latent heat per unit weight and better thermal conductivity) than R12. In practice, this means the charge required, in weight terms, is lower than for R12 and R134a to give the same volumetric flow rate and the same capacity.

What is a substitute for R12?

There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.

Is 12a the same as R134a?

HC-12a provides better cooling than an R-12 system retrofitted to R-134a, with much greater energy efficiency as well. Unlike R-134a, HC-12a is completely compatible with the hoses and oils used in R-12 systems, making the conversion much easier to accomplish.

Can R12 still be used?

It is illegal to manufacture new R12, but it is not illegal to sell or use R12. And many of the cylinders and cans of Freon R-12 sold for decades throughout the United States are still around.

Can you mix R12 and 134a Freon?

Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.

Don't Buy Cars that Use this New Type of Refrigerant in the AC System

What happens if you put R134a in a R12 system?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

What happens if you put the wrong refrigerant in your car?

You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you're not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

Is R12 illegal?

It's often said that buying or selling R12 is illegal. That's not true either. Anyone selling R12 is required to verify that the buyer has an EPA Section 609 certification to work with mobile vehicle air conditioning (MVAC) systems.

Can I sell my R12 refrigerant?

Yes, you can still sell R-12 and other CFC refrigerants. Although these refrigerants can no longer be manufactured, it is perfectly legal to sell to an EPA certified buyer.

How much does it cost to convert R12 to R134a?

R12 to R134a Charge Conversion Formula (pounds only)

Take the R12 charge specification and multiply it by 0.9. Then, subtract that result by 0.25 pounds to get the proper amount of R134a charge.

Can you put 12a in R12 system?

RED TEK 12a requires no significant redesigning of the refrigeration system because it is compatible with R134a, R12, metal components, compressor motor materials, mineral, and synthetic (Ester and PAG) lubricants, seals, gaskets, hoses, compressors, and O-rings.

Is r12a flammable?

Emergency Overview.................................... Extremely flammable. Container is under pressure. Container may explode if heated.

What refrigerant can be mixed with R134a?

There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744.

Is R12 and R22 the same?

R12 and R22 are two refrigerating agents for air conditioning units. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.

Can R12 and R22 be mixed?

They are two completely different refrigerants,won't mix at all. But when it blows your system have the decency to tell the service tech what ya did. I have a R12 in basement for long time.

How much is reclaimed R22 worth?

The current cash buyback price for R-22 is $6.00/lb. when consolidated into 250# and/or ½ ton refrigerant recovery cylinders. The current credit buyback price is $7.00/lb.

Can you sell reclaimed refrigerant?

No. EPA prohibits the sale of used refrigerant for use in an appliance unless that refrigerant has been reclaimed by an EPA certified reclaimer.

What uses R12 refrigerant?

Refrigerant R12 is used in domestic refrigerators and freezers, liquid chillers, dehumidifiers, ice makers, water coolers, water fountains and transport refrigeration. The wide range of applications of the refrigerant are due to its safe properties.

How do I switch from R12 to R134a?

Why did they stop making R12?

But Freon was shown to deplete the earth's vital ozone layer. So carmakers were mandated to stop using R12 after the 1994 model year. The current replacement refrigerant is R134a, which serves the same purpose as Freon but is less harmful to the environment.

What happens when you mix two different refrigerants?

What Happens to Your AC System if You Mix Refrigerants? Mixed refrigerants can cause increased system pressures and temperatures changing them for the worse. This can result in ineffective compressor cooling and possible compressor damage, ineffective cooling, and metering device malfunction.

Can I add refrigerant to my vehicle when it is cold outside?

Anything below that does not allow the system to build up enough pressure for a proper reading on your A/C Pro pressure gauge. Because of this, adding refrigerant to your vehicle is not recommended when the ambient temperature is under 65ºF.

Will AutoZone recharge my AC?
