Is PAG oil compatible with R134a?

➔ PAG oils are highly miscible with R134a (PAG oils 46 YF and 100 YF also with R1234yf

R1234yf

2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with the formula CH₂=CFCF₃. It is also designated R-1234yf as the first of a new class of refrigerants: it is marketed under the name Opteon YF by Chemours and as Solstice YF by Honeywell.

) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles. ➔ The choice of the right viscosity is crucial when using PAG oils (PAG 46, PAG 100, PAG 150).

Does R134a contain PAG oil?

Summary: PAG Oil is used on R-134a systems from about 1995-2015. Check your manufacturer's recommendation for proper type of oil as well as specific viscosity. Because mineral oil and PAG oil cannot be mixed, another A/C compressor oil was needed to bridge the gap for system conversions.

Does PAG oil mix with refrigerant?

Oil and refrigerant vapor do not mix readily, and the oil can be properly circulated through the system only if gas velocities are high enough to sweep the oil along.

What type of oil do you use with R134a?

Polyolester oil is a type of synthetic oil that is compatible with the R-134a, R-410A and R-12 refrigerants.

What refrigerants use PAG oil?

PAG oil YF is suitable for both R1234yf and R134a refrigerants. PAG SP-A2 oil for refrigerants R1234yf and R134a For use in electric air conditioning compressors, such as those manufactured by SANDEN and VISTEON (Hanon).

Understanding AC System Lubricants

Is pag 46 compatible with R134a?

➔ PAG oils are highly miscible with R134a (PAG oils 46 YF and 100 YF also with R1234yf) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles.

What happens if I use the wrong PAG oil?

Using the wrong oil may allow current to short circuit back through the A/C compressor, creating a shock hazard. Mineral oil should only be used in older R-12 A/C compressors because R-12 will not mix with R-134 refrigerant.

What kind of oil goes in an AC compressor?

PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. Most all newer model cars use PAG as the lubricant in the A/C system.

What is the difference between Poe and Pag oil?

Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems. ​​Polyalkylene​ Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems.

What is pag 46 refrigerant oil?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

Do I need to add oil when recharging AC?

The best way to ensure the long life of your AC compressor is to ensure that you add adequate oil any time you add refrigerant to your system. If you've discovered a need for more refrigerant in your vehicle, add BlueDevil Red Angel One Shot.

Should I add oil when replacing AC condenser?

When replacing a part like the condenser it is a good idea to add some extra oil with the new refrigerant. Most refrigerants do have some oil in them which should be enough. The majority of the oil in the system stays in the compressor so you should not have any issues if you do not add any more.

Can you mix different PAG oils?

The two oils do not mix completely and cannot create a long-lasting homogenous mixture, which is needed to ensure the correct lubrication of the mechanical parts within the compressor.

Can I use Poe instead of PAG?

PAO oil: Polyalphaolefin- or PAO-based oil is a multi-grade synthetic oil. Compatible with many lubricants and refrigerants, it is intended for universal application and is sometimes used as a substitute for certain PAG oils if approved by the compressor manufacturer.

Is R134a a Poe?

Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12.

Can you mix synthetic R134a with non synthetic?

A: No can do. The system will have to be evacuated properly, to remove any oil and any water or humidity that got in. Then you can add the correct amount of oil and refrigerant, in this case R134a. Modern a/c systems don't use very much refrigerant, and they're pretty intolerant of being overcharged.

Do I need to add PAG oil after vacuum?

Absolutely not. You don't need to add any oil and there will be some oil in the refrigerant when you charge the system. Pull a good vacuum with a Micron gauge to 500 microns. This will ensure all the moisture is out of the system.

What type of refrigerant oil should be used on the O ring seals with a 134a system?

Polyalkylene Glycol (PAG) oil

PAG oil is a man-made lubricant that is used in R134a and R-1234yf A/C systems, although the two types of PAG oil are different.

Can you add too much oil to AC compressor?

If you add too much oil to the system, it may pool in various places of the system and can coat the inner walls of the evaporator and condenser coils. This will diminish their ability to absorb or dissipate heat, thereby bringing down the overall cooling performance.

What is PAG 150 oil used for?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

What is PAG 100 oil used for?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

What is PAG 68 oil?

PAG 68 for CO₂, based on the “capped PAG” technology, provides effective lubrication for refrigeration units and compression. Protection technology (“capped” technology) also provides improved lubricity for CO₂ systems. High efficiency of the process typically results in ~ 95% for PAG 68 for the CO₂ range.

What color is AC compressor oil?

Refrigerant or PAG (synthetic compressor) oil is clear, he explains. Over time, it picks up moisture and turns acidic, eating away at the condenser, thermal expansion valve, evaporator, fittings, compressor and other metal components. Gradually, the oil turns yellow and darkens as it picks up particles and sludge.
