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. 6.2% vol.; 12.3% vol.

) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles.

Is Pag 100 the same as Pag 46?

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.

Can you mix different 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.

Which PAG oil is universal?

PAG - 100 (Medium Viscosity) developed as a "universal" in PAG systems using R-134A.

Is pag 46 universal?

Fluoro-Dye PAG – 46 (Light Viscosity) with MPD Universal A/C Dye. Polyalkylene glycol developed for use as a universal Pag Oil for auto systems using HFC 134a. This Pag Oil is compatible with most other Pag Oils available on the market.

PAG 46 AND PAG 100 COMPRESSOR OIL

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.

Is pag 46 compatible with sp10?

plate compressors, and is compatible with SP-10 oil. to SP-10 and SP-20 compressor oils. > PAG 46 - double end-capped oil similar to SP-10 for use in aftermarket A/C systems.

What kind of oil goes in 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.

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.

What is ND8 PAG oil?

Product Details. Our 46V Denso ND8 PAG oil for air conditioning compressors will keep your system properly lubricated during those long hours in the hot summer sun. This 8.5 ounce bottle of synthetic Polyalkylene Glycol refrigerant oil is specially formulated to work with refrigerants like R134a and R12.

What is the difference between PAG oil and POE oil?

Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems. ​​Polyalkylene​ Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems.

What is PAG oil?

PAG oil: Polyalkylene Glycol or PAG oil is a man-made lubricant used in both R134a systems and the latest R1234yf. 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.

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.

How much PAG oil do I put in a compressor?

Here is the amount of PAG oil that different AC components require for their smooth operation: Compressor = 1.4 ounces. Evaporator = 1.5 ounces. Condenser = 1 ounces.

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.

How long should you vacuum AC system?

When concerned as to how long to vacuum AC system, you should know that usually it would take around 30-45 minutes if there is no leak in the pump. This is enough time period to get rid of moisture and dust inside the AC system.

Does evacuating an AC system remove the oil?

To answer the question title, yes, you will have to add oil to the new refrigerant. Failure to do so will shorten the useful life of the A/C compressor's bearings through lack of lubrication. This will invariably lead to premature death of the compressor.

What oil is best for compressor?

For compressor oil, you want to use either SAE 20 or SAE 30 oil, where the latter is the more viscous of the two. If you live in a cold region, then it is better to go for SAE 20 compressor oil. Those who live in warmer places should use SAE 30. This is based on how the viscosity may change depending on the weather.

Does compressor oil mixing with refrigerant?

Oil and refrigerant vapor do not mix readily, and the oil can be properly circulated through the system only if gas velocities are high enough to sweep the oil along.

What color is AC compressor oil?

Refrigerant or PAG (synthetic compressor) oil is clear, he explains. Over time, it picks up moisture and turns acidic, eating away at the condenser, thermal expansion valve, evaporator, fittings, compressor and other metal components. Gradually, the oil turns yellow and darkens as it picks up particles and sludge.

How do you know if your AC has too much oil?

Inefficient Cooling

The most glaring sign of an overfilled AC system is poor cooling because an internal coating forms resulting in reduced heat transfer. For instance, you might notice that it's taking way too long to cool things or your windows stop defogging properly.
