Is PAG oil hygroscopic?

Is Pao oil hygroscopic?

PAO oil for refrigerant R134a, and in some cases for refrigerant R1234yf and others Can be used as an alternative to the various PAG oils that are offered for R134a (has the advantage of not being hygroscopic, i.e., unlike other oils, it does not absorb any moisture from the ambient air).

Is refrigerant oil hygroscopic?

It is more hygroscopic that either POE or PVE oils, but it does not undergo hydrolysis in the presence of water. Polyvinyl Ether (PVE) – a synthetic oil that is being used as an alternative to POE oil.

Does POE and PAG oil absorb moisture?

All POE oils are highly hydroscopic; they absorb moisture quickly and hold the moisture they absorb. Once absorbed, the moisture cannot be removed through system evacuation even at a vacuum pressure as low as 500 microns (millitorr).

What type of oil is PAG oil?

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. When people refer to PAG oil they typically refer to it in the following terms: PAG 46, PAG 100, or PAG 150.

Does PAG oil evaporate?

PAG oil tends to evaporate rapidly when exposed to air (unlike mineral oil).

Is PAG oil water soluble?

PAG base fluids are available in both water soluble and insoluble forms, and in a wide range of viscosity grades. They offer low volatility in high-temperature applications and can be used in high- and low-temperature environments.

Is POE oil hygroscopic?

One major concern with POE oils is that they are hygroscopic. If they remain in contact with air, they have the ability to absorb its moisture. For a technician, this means that when a repair requires opening a system, it should only be left exposed to the atmosphere for as long as necessary to complete the repair.

Can you mix POE oil and PAG oil?

Because mineral oil and PAG oil cannot be mixed, another A/C compressor oil was needed to bridge the gap for system conversions. The transitional solution was polyol ester oil (“ester” oil or POE). Ester oil is often called “retrofit oil” because it mixes with both R-12 and R-134a.

Why should you always use mineral oil instead of PAG oil to lubricate the O-rings on an AC line?

Mineral oil is natural oil and is not hygroscopic, making it different to PAG. In automobile A/C systems, mineral oil is used in those systems that utilise R-12 refrigerant and is also used to lubricate O-rings and seals on both R-12 and R134a systems.

What is the difference between PAG and ester oil?
