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

Product Information

Due to the great variety of different applications and storage and processing conditions, we cannot guarantee a particular application result. PAO Oil (Polyalfaoleifin) – A mineral synthetic oil commonly used in car motor vehicles, PAO has low hygroscopicity properties and won’t introduce unwanted moisture when added to the system. Generally, you should be looking to re-gas your air con system every two years, as it naturally leaks gas over time. Interestingly, the R134a refill bottles sold at Halfords have almost the exact correct ratio of refrigerant to Pag oil (within ~0.

Refrigerant burns at a -30deg onto open skin is nasty, everything will be covered in oil, you don't want oil or refrigerant in your eyes, refrigerant liquid will blind you.They have been developed to provide optimum miscibility and compatibility with HFC refrigerants such as R-134a and R404A and can also be used with HCFCs such as R22. If the smell is only noticeable when the A/C is on, it’s probably because your vehicle lacks A/C compressor oil. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Scroll through this page and find out about the different variants of refrigerant and compressor oils. My near final bit of advise is to fit the compressor and then leave the rest for a A/C engineer to purge the system, replace the drier, leak test and then vacuum the system.

Due to their good miscibility with refrigerants are the best choice for applications with HFC / FC R134a, R404A, R407C.Under normal atmospheric pressure and ambient temperatures, liquid refrigerant evaporates so quickly that any physical contact with the skin or eyes can cause the tissue to freeze (risk of blindness). The most common lubricant used in automotive air conditioning systems is Polyalkylene Glycol oil, commonly known as Pag oil. R134a can, however, continue to be used to carry out service and maintenance work on existing R134a systems. The above application instructions are recommendations given on the basis of our own tests and experience. Consequently, when the compressor starts from cold, the differing density and viscosity of the oils will result in imprecise lubrication inside the AC compressor, leading to friction, overheating and seizure.

PAG oil: Polyalkylene Glycol or PAG oil is a man-made lubricant used in both R134a systems and the latest R1234yf. If direct physical contact has been made, thoroughly rinse the affected areas with a generous supply of cold water. The high viscosity index ensures excellent low temperature flowability and a stable film at high temperatures, confirming the maximum efficiency under all operating conditions.But do you know the difference between the various types of oil, and how and when they should be used? This, coupled with the fact that the compressor is pre-filled, will help to ensure a best-practice repair, whilst saving garages both time and money. There are still numerous vehicles on the market with air-conditioning systems originally designed for refrigerant R12. To comply with the latest European Union environmental requirements, vehicle manufacturers are transitioning to a new A/C refrigerant – R1234yf. Our ASE-certified mechanics can address any additional issues that are likely to result from a lack of compressor oil and apply the proper repairs quickly.
