Product Information

PAG polymers, first discovered more than 150 years ago, saw their breakthrough application occur during World War ll. At that time, both fires on U.S. Navy ships and aircraft were occurring due to the use of mineral oil-based hydraulic fluids. Research at the U.S. Naval Research Laboratory (USNRL) was begun to develop hydraulic fluids that would be more fire-resistant than the ones used at the time based on mineral oil. PAG oils are classified by their weight percent composition of oxypropylene versus oxyethylene units in the polymer chain. PAG oil with 100 weight percent oxypropylene groups are water insoluble; whereas those with 50 to 75 weight percent oxyethylene are water soluble at ambient temperatures. 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:

Polyalkylene glycol (PAG) and polyalphaolefin (PAO) are two synthetic lubricant options for industrial applications. Understanding the advantages and disadvantages of each can help end-users decide which option is best for a given application. Why Synthetic Lubricants? For centuries, lubricants have been utilized as a way to reduce friction and wear on moving parts. In 2005, 40 million tons of lubricants were produced. The choice between pag and poe oil depends on the specific requirements of your ac system. Pag oil is commonly used with r134a refrigerant, while poe oil is recommended for systems with r410a refrigerant. Consult your manufacturer’s guidelines for the best choice. Can I Use Pag Oil If My Ac System Originally Had Poe Oil? CAUTION: Do NOT overfill the the A/C system with too much compressor oil. Too much oil can hurt cooling performance.When it comes to automotive air conditioning systems, choosing the right oil is crucial for optimal performance and longevity. The wrong choice can lead to inefficient cooling, increased wear and tear on components, and potential system failure. Two commonly used oils in automotive air conditioning systems are pag and poe oil. With the exception of a few European models, vehicles newer than 1995 typically do not contain ester oil as the lubricant for the A/C system. Still, it is imperative that you look up the lubricant specifications for your particular car to determine the oil quantity and replacement type. Summary Pag oil provides excellent lubrication, enhancing the efficiency and lifespan of the hvac system components.

Proper maintenance and compatibility considerations are key to ensuring optimal system performance and efficiency. Pag Vs Poe Oil: Performance Comparison 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 lubricatePotential 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. The push for more eco-friendly materials and more stringent vehicle engineering standards has led to a number of changes to manufacturer requirements for A/C compressor oils over the past two decades. Oil is an important ingredient for keeping your AC system running smoothly. Not only does it provide a film on heat-sensitive components to reduce friction and wear, but also controls the amount of pressure that refrigerant gases need to move through them – which creates waste without oil! For this machine to work its best; there needs plenty of never-ending supply from your vehicle’s manufacturer so they can be stored appropriately at all times (until needed).

Another recommended scenario for using pag oil is in refrigeration systems that operate at low temperatures, as it offers good lubricity in such conditions. Newer vehicles with R-1234yf A/C systems require a special PAG YF 46 or PAG YF 100 compressor oil, which one depends on the compressor and the requirements of the vehicle manufacturer.PAG oils are also valued for their low volatility in high-temperature applications, and for resistance to formation of residue and deposits. Their biodegradability makes them ideal for environmentally sensitive applications. Chemical stability: Pag and poe oil have different chemical compositions, and their stability under different conditions can vary. Ensure that the oil you choose has the necessary stability to withstand the demands of your air conditioning system. PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. Most newer model cars use PAG as the lubricant in the A/C system. Poe oil is recommended for systems that use r410a refrigerant, as it has outstanding compatibility with this refrigerant. Pag oil and poe oil are two different types of lubricants used in automotive air conditioning systems. Pag oil is synthetic oil that offers excellent lubrication and compatibility with r134a refrigerant, while poe oil is a synthetic lubricant suitable for use with both r134a and r1234yf refrigerants.

First, they cannot be used in the cylinder lubrication of internal combustion engines because the combustion by-product is silicon dioxide.The main difference lies in their composition, with pag oil being a polyalkylene glycol while poe oil is a polyol ester.
