What is r414b used for?

R-414B (HOTSHOT)* is a blend of R-22, R-124 and R-142b with hydrocarbon R-600a (isobutane) added to improve mineral oil miscibility. This blend can be used to retrofit R-12 automotive air conditioning systems as well as stationary refrigeration systems.

Can you mix hot shot with r12?

Yes its a no no to mix any refrigerant. Some techs read that you can top off units with hotshot which means by manufacture that you can add a little more to a unit that already has pure 414 in it. It never means you can top off unit with r12 in it.

Is there a replacement for R12 refrigerant?

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 R12 freon?

Because of this, in the early 1930s, a new refrigerant based on a chlorofluorocarbon (CFC), specifically dichlorodifluoromethane, was developed. It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable.

Is hotshot a direct replacement for R12?

Hot Shot 2 as an ozone safe, reliable, and affordable HFC replacement for R-12 and other R-12 interim replacements. Hot Shot 2 has been extensively field tested in a variety of applications and we are confident you will be pleased with its performance.

What happens if you mix R12 and r134?

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.

What is the best replacement for R12?

The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.

Can you mix 134a with R12?

What replaces R12 freon?

Can you top off R12 with R134a?

No. Federal law prohibits topping off an R12 system with a different refrigerant. Your options are to locate some R12, however you must be certified to purchase, and add it with an R-12 recharge hose.

Can I still buy R12 refrigerant?

As R12 became scarce, garages and warehouses discovered a supply of the stuff, which is available to buy on eBay Motors and elsewhere. To be clear, it’s against the law to manufacture Freon. But it’s still perfectly legal to sell R12 refrigerant.

Is there any refrigerant that is compatible with R12?

What happens if you put r134 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.

Is R12 Freon illegal?

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.
