LIQUI MOLY PAG Air Conditioning Oil 46 | 250 ml | Compressor Oil | SKU: 4083

Product Information

Another distinguishing factor is their compatibility with different materials; while pag oil can be detrimental to certain types of seals and hoses, poe oil is generally compatible with most materials used in refrigeration systems. Poe oil, or polyol ester oil, is another type of synthetic lubricant used in refrigeration and air conditioning systems.

While natural mineral oil-based fluids represent the majority of the market demand, many technological advances in equipment and machinery would not be possible without the benefits offered by improvements in synthetic lubricants, which currently make up only two percent of the market. Enhanced lubrication: Pag oil is known for its excellent lubricating properties, which help reduce friction and wear in machinery and equipment. This leads to improved performance and longevity of the components. Potential for contamination: If pag oil is not properly handled or stored, it can become contaminated with moisture, dirt, or other contaminants. Contaminated oil can negatively impact system performance and efficiency.

Versatility Meets Performance

Compatibility considerations: Although poe oil is compatible with a wide range of refrigerants, it may not be suitable for all systems. It is crucial to consider the specific requirements of the system and consult with experts to ensure optimal compatibility and performance. Mineral refrigerant oil, also known as Alkyl Benzene Oil, was the default option up until HFC refrigerants became common place. Today it is still used in older R-12 refrigerant systems. And because it does not absorb moisture, it is also used to lubricate

Higher cost: Compared to traditional oils, poe oil tends to be more expensive. The increased cost can be a limiting factor for some applications, especially when budget constraints come into play. So, how much PAG oil to add when recharging AC ? Here is the amount of PAG oil that different AC components require for their smooth operation: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. Like PAG oil, Ester oil is a synthetic lubricant. Ester molecules are very stable and have excellent performance characteristics in both high and low temperature environments. Ester oil comes in only one viscosity so it does not include the viscosity numbers associated with PAG oils. FJC offers Ester oil with Extreme Cold and Fluorescent Dye additives. Since R-12 was phased out in 1994, vehicles newer than 1995 typically do not contain ester oil as the lubricant for the A/C system. In refrigeration compression, PAG and polyol ester-type lubricants are used almost exclusively with the current generation of environmentally friendly HFC refrigerants such as R-134a and R-152a. for. Unfortunately PAG is hygroscopic, meaning it attracts and retains moisture from within the A/C system or atmosphere. When PAG oil and moisture mix, they react, creating an acid that can corrode and damage system related components. For this It is an ideal option for systems that require high moisture resistance, as poe oil exhibits better hydrolytic stability compared to pag oil. With all the variations between compressor oils on the market, the one-size-fits-all utility of universal oils would seem to be a godsend for automotive technicians.
