Change r12 to 134a

Soon after research and studies scientists concluded that R12 a CFC gas was harmful to the ozone layer and thus damaged it which is why alternatives to R12 were chosen. R-134a O-rings are blue or green in color.

Yes R-12 and R134a will ignite but not at the rate of hydrocarbons such as propane or LP gas.

Change r12 to 134a. Soon after research and studies scientists concluded that R12 a CFC gas was harmful to the ozone layer and thus damaged it which is why alternatives to R12 were chosen. One alternative to the refrigerant R12 is R134A.

Open the engine compartment of your vehicle. Find the high and low side service ports for the R12 air-conditioning system. Push the low side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

Torque the fitting to 20 foot-pounds. R134a Charging Hose to Refrigerator - with Gauge - R-134a can to R-12R-22 Port Include R12 to R134a Conversion Kit for AC Pro Refrigerant BPV31 Piercing Valve 41 out of 5 stars 121 2699 26. There are two ways to convert your cars old R12 system to R134a.

The factory method and the easy method. The factory method is the best choice because youll replace parts that are probably leaking due to age. Plus youll get the best AC performance using the factory method.

Unfortunately its more costly and time consuming. Converting to 134a - GM Cars R-12 Freon Until 1995 most cars with air conditioning used R-12 Freon refrigerant which has shown to have an environmental impact. R-12 is no longer used or produced in many countries and remaining quantities have skyrocketed in price.

The refrigerant must be recovered and needs to be unadulterated R12. Also all of the oil in the system needs to be purged because it will gel in a R134a system. Big fine if you get caught.

Converting to 134a - Mopar Until 1995 most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. Since then the industry standard has been R134a which is an efficient replacement. Yes R-12 and R134a will ignite but not at the rate of hydrocarbons such as propane or LP gas.

Make your own choice but personally I will not use anything but pure R-12 or R134a or whatever the new freon is that is supposed to be in the newer cars coming out. The new ester oil will settle on top of the mineral oil and will be moved thru the system with the 134a so thats not a problem. So recover the R-12 remove old shrader valves install the 134a change over fittings.

Vaccuum the system down and add 2 or 3 ounces ester oil in high and low side. R134a refrigerant O-rings are of a different composition than those for R12 systems. R-12 O-rings are black in color.

R-134a O-rings are blue or green in color. Ester oil charge for lubrication amount varies by model year. You can also use PAG Poly Alkylene Glycol or Castrol Retro Oil for lubricant.

R134a refrigerant amount varies by model. One way to improve cooling performance when retrofitting an older R-12 system to R-134a is to install a variable valve orifice tube in place of the standard fixed orifice tube. These aftermarket variable orifice tubes allow the flow rate through the valve to change for better cooling at idle and low speeds.

R12 is not illegal. Though it is no longer in production in most countries Congress has mandated that R12 be available to qualified technicians in reserve recycled forms until the year 2030. Most people are concerned with converting to 134a fearing that its an inferior refrigerant.

R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1112-tetrafluoroethane R-134a which has an insignificant ozone depletion potentialAutomobile manufacturers started using R-134a instead of R-12 in 19921994. Retrofit Kits Our Retrofit Kits will update your older vehicles refrigerant from R-12 to R-134a making your system cost-effective colder and environmentally friendly. In the automotive world the replacement for R12 was tetrafluoroethane a hydrofluorocarbon HFC branded as R134a.

Note that R134a is also sometimes called Freon even labeled as such on the can so its best to be clear and use the names R12 and R134a.
