Product Information

Compatibility: Pag oil is compatible with a wide range of materials such as metals, plastics, and elastomers. This makes it suitable for use in various systems and components.

Pag oil, short for polyalkylene glycol oil, is a type of lubricant commonly used in automotive air conditioning systems. Phosphate Esters are valued in applications where safety and fire resistance are critical considerations, which include fire-resistant hydraulic fluids and aircraft fluids. High flash points and fire points enhance their resistance to ignition, and their low heat of combustion makes them excellent self-extinguishing fluids. However, they do have several weaknesses including poor hydrolytic stability, which can lead to the formation of aggressive acidic by-products. Care must be taken when used because they can also react and degrade a variety of commonly used sealants and paints. If there is a leak in the system, fix it first before adding oil to it. Otherwise, the system will require more oil soon and may lead to the failure of some parts. What Is PAG Oil?Are synthetic oils (PAO - Polyalpha olefin and PAG - Polyalkylene glycol) better gear and bearing lubricants than mineral oils? When it comes to selecting between pag and poe oil for various applications, it’s essential to consider the specific requirements of your system. Here are some key points to consider: 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. Unlike pag oil, poe oil is hydrophobic, meaning it does not absorb moisture, making it less susceptible to degradation due to water. 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.

Reduced system lifespan: While poe oil offers great lubrication, the hygroscopic nature can pose challenges. If moisture is not properly managed within the system, it can lead to corrosion and premature failure of components. Regular maintenance and moisture control measures are crucial to mitigate this risk. Never allow refrigerant to leak out into the atmosphere. If the refrigerant reservoir or air-conditioning system is opened, its contents will escape under high pressure. The extent of the pressure depends on the temperature. The higher the temperature, the higher the pressure. Poe oil, also known as polyolester oil, has gained popularity in various applications such as refrigeration and air conditioning systems due to its unique properties. However, like any other product, poe oil also has its advantages and disadvantages. In this section, we will explore the pros and cons of poe oil, along with its impact on system performance and efficiency. Advantages Of Using Poe Oil In Various Applications To determine the right PAG viscosity and quantities for your car look up the specifications for your make, model, and year of car. Ester Oil Explained 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.PAG oils might reign supreme in the hierarchy of today’s compressor oils, but that doesn’t mean there aren’t some very important exceptions to be mindful of. Polyalphaolefin (PAO) oil can be used as a replacement for some PAG oils, and is sometimes preferred because it doesn’t absorb moisture from the air like other oils do. It is not recommended to mix Pag and Poe oil in the same HVAC system. Mixing different oils can lead to reduced lubrication effectiveness and potential damage to the compressor and other system components. How do I determine which oil my HVAC system needs? Choosing the wrong type of oil can negatively affect both the performance and longevity of thecompressor. In fact, using the wrong type of oil is one of the biggest causes of failure in a newly installed compressor. There are still numerous vehicles on the market with air-conditioning systems originally designed for refrigerant R12. 2001 marked the official final end of R12 in vehicle air-conditioning systems. Ever since then, R12 systems had to be converted during maintenance or repair work. R134a was and is used as replacement refrigerant besides several "drop-in" refrigerants (refrigerant mixtures). R-134a has dominated the U.S. market for roughly two decades, but it too is beginning to be eclipsed by a new refrigerant due to environmental concerns. While R-134a does not deplete the ozone like R-12, it has been shown to have notable global warming potential (GWP). For this reason, R-1234yf was developed for its cooling abilities and its low GWP.

Poe oil is compatible with various refrigerants, including R-410A, R-404A, and R-507, among others. It is widely used in newer HVAC systems due to its compatibility with environmentally friendly refrigerants. Can I mix Pag and Poe oil in my HVAC system?Another recommended scenario for using pag oil is in refrigeration systems that operate at low temperatures, as it offers good lubricity in such conditions. Our advice is this: Why take a chance using a universal oil when you can just as easily use the correct PAG oil? Poe oil is known for its excellent lubricity, high chemical stability, and compatibility with various refrigerants. As you know that all moving auto parts in the car need lubrication for smooth work. Without enough amount of lubrication, the moving part will eat away due to friction. Similarly, the cooling system parts are subjected to continuous vibration. So, it is necessary for the A/C parts to be flexible enough to stand with vibration.

However, because mineral oil and PAG oil are not to be mixed, another compressor oil was needed to bridge the gap. The solution was ester oil. Apart from lubrication properties, compatibility with different refrigerants is a critical factor to consider. Let’s explore how pag oil and poe oil fare in this aspect:However, as the temperature changes, the relationship changes, leaving us with clear direction for when we could expect to see which synthetics demonstrate superior film-forming capability in a temperature range. At the heart of the issue is a property we refer to as pressure-viscosity coefficient of the various types of lubricant base oils.
