➔ PAG oils are highly miscible with R134a (PAG oils 46 YF and 100 YF also with R1234yf

R1234yf

2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with the formula CH₂=CFCF₃. It is also designated R-1234yf as the first of a new class of refrigerants: it is marketed under the name Opteon YF by Chemours and as Solstice YF by Honeywell.

) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles. ➔ The choice of the right viscosity is crucial when using PAG oils (PAG 46, PAG 100, PAG 150).

How do I know which PAG oil to use?

PAG oils are harsher than mineral oils, and may cause skin irritation and damage O-rings and seals. There are different viscosities of PAG oil being used by OEMs: PAG 46, which is the most popular; PAG 100, which is also common; and PAG 150, which is more rarely used.

Are all PAG 46 oils the same?

Because the various PAG oils all have different viscosities, it is virtually IMPOSSIBLE to have a single oil formulation with the same viscosity characteristics as the original PAG 46, PAG 100 or PAG 150.

What are the different PAG oils?

There are several types of PAG oil based on the viscosity of the oil -- PAG46, PAG100 and PAG150 -- and the type of refrigerant it is designed for. Unfortunately PAG is hygroscopic, meaning it attracts and retains moisture from within the A/C system or atmosphere.

What is pag 46 used for?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

Understanding AC System Lubricants

What is PAG 150 oil used for?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

Can you mix PAG oils?

The two oils do not mix completely and cannot create a long-lasting homogenous mixture, which is needed to ensure the correct lubrication of the mechanical parts within the compressor.

What oil do I put in my AC compressor?

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.

Is pag 46 compatible with R134a?

➔ PAG oils are highly miscible with R134a (PAG oils 46 YF and 100 YF also with R1234yf) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles.

What kind of oil goes in a compressor?

There are two main types of compressor oil: standard oil (also called mineral oil) and synthetic oil. Standard (Mineral) Compressor Oil. Standard compressor oil is made by using a mineral base and are cheaper than synthetic compressor oil. Mineral oil is more volatile and is more likely to evaporate than synthetic oil.

Do I need to add PAG oil after vacuum?

Absolutely not. You don't need to add any oil and there will be some oil in the refrigerant when you charge the system. Pull a good vacuum with a Micron gauge to 500 microns. This will ensure all the moisture is out of the system.

Can you add too much oil to AC compressor?

If you add too much oil to the system, it may pool in various places of the system and can coat the inner walls of the evaporator and condenser coils. This will diminish their ability to absorb or dissipate heat, thereby bringing down the overall cooling performance.

What is PAG 68 oil?

PAG 68 for CO₂, based on the “capped PAG” technology, provides effective lubrication for refrigeration units and compression. Protection technology (“capped” technology) also provides improved lubricity for CO₂ systems.

Is Pag 100 the same as SP 20?

> PAG 100 - double end-capped oil similar to SP-20 for use in aftermarket A/C systems.

Does r134 have PAG oil in it?

With R-134a, there are primarily three different viscosities of PAG oil being used: PAG 46, which is the most popular viscosity oil; PAG 100, which is also common; and PAG 150, which is not often used, but it is still required for a certain compressor used in some GM vehicles from the '90s to the early 2000s.

What type of oil do you use with R134a?

Polyolester oil is a type of synthetic oil that is compatible with the R-134a, R-410A and R-12 refrigerants. Experts say it is a good substitute for hydrofluorocarbons.

How much PAG oil do I put in a compressor?

Lets add oil back to the new compressor in an amount equal to the amount drained from the old compressor. 3 oz. Old Compressor 2 oz. Old Dryer 5 oz needed in new compressor Typically you'll want to change the receiver dryer along with the compressor.

Do I need to add oil after replacing condenser?

When replacing a part like the condenser it is a good idea to add some extra oil with the new refrigerant. Most refrigerants do have some oil in them which should be enough. The majority of the oil in the system stays in the compressor so you should not have any issues if you do not add any more.

How do I know if my AC compressor needs oil?

One of the earliest signs that the AC compressor is operating with an insufficient oil amount is the emergence of humming noises from your air-conditioning system. At the same time, you may notice that the compressor has suddenly become hard to start.

What is SP 15 Pag?

The SP-15 PAG Oil 8.45oz is designed for use with R-134a Sanden Compressors.

What Colour is PAG oil?

Leaks can be detected quickly using a UV lamp thanks to the yellow fluorescent color.

What does Pag stand for in oil?

One of the most versatile types of synthetics is polyalkylene glycol (PAG) lubricants. PAGs are generally known as compressor lubricants, and their use in industry has increased since the 1980s.

Can you mix synthetic R134a with non synthetic?

A: No can do. The system will have to be evacuated properly, to remove any oil and any water or humidity that got in. Then you can add the correct amount of oil and refrigerant, in this case R134a. Modern a/c systems don't use very much refrigerant, and they're pretty intolerant of being overcharged.
