What type of oil is specified for R-1234yf systems?

As new models are redesigned or introduced, they will have R-1234yf with POE oil. The POE oil that is required for this system on Honda vehicles is not the same oil that is required for hybrids. Honda has three types of POE oil, and the POE required for R-1234yf is its own specific product.

Which oil can be used in an R134a system?

Polyolester oil
Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12. It is recommended by experts as a replacement for hydrofluorocarbons (HFCs).

Is 1234yf oil compatible with 134a?

While R-1234yf oils are backwards compatible with R-134a systems, R-134a PAG oils are not compatible with R-1234yf systems.

What kind of oil does a AC compressor use?

The two categories of oils commonly used in the compressors are mineral or synthetic oils. One type of mineral oil (MO) called Naphthenic is commonly used. Synthetic oils such as glycols, esters and alkylbenzenes (AB) have been used in the refrigeration applications for some time without any problem.

Can PAG 46 and PAG 100 be mixed?

Note: Using the wrong oil can cause damage. ➔ 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.

How much refrigerant oil should I add?

The AC system requires a Usually of 4 ounces (120 ml) of oil in most modern automobiles. So it is a good idea to test the manual to be sure of the exact amount and to prevent over- or under-filling of the system. Low oil levels can cause compression failure and overfill often hurts the efficiency of the cooling cycle.

Is refrigerant oil harmful?

When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals. Even small amounts can cause symptoms.

Can you mix r134 and R134a?

Maikal, when you say R-134a, it is the same chemical. So, whether you are adding it all from 1 manufacturer or from 5 different ones, it doesn’t matter.

Does R134a have oil in it?

Yes there is oil in the system to keep the compressor lubricated. It is carried throughout the system in the refrigerant. It is usually added in when the system is charged.

What is PAG 46 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.

What happens if I use the wrong PAG oil?

The use of low-quality or even the wrong oil – just like with the engine – leads to increased wear, premature compressor failure, and loss of warranty/guarantee. Note: Using the wrong oil can cause damage. ➔ The choice of the right viscosity is crucial when using PAG oils (PAG 46, PAG 100, PAG 150).

Can you add too much oil to AC compressor?

While installing a new compressor or any other parts in your AC system, it is imperative that you add the correct amount of oil. 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.

What kind of refrigerant is R-32 used for?

In fact, R-32 is used in quite a bit of blends in today’s world. It is used to create various refrigerants such as: R-410A, R-407A, R-407B, R-407C, R-407D, R-407E, R-407F and R-410B. R-32 along with R-125 are some of the most versatile refrigerants used today.

What kind of oil does a R-22 air conditioner use?

Chances are that if you have an older R-22 unit installed that it is most likely using mineral oil. These types of oils have been used in refrigeration for decades. When HFC refrigerants began to gain popularity the use of mineral oils started to decline.

What kind of oil is used in refrigerant systems?

Until recently mineral oils were the default lubricant used in refrigeration systems. Chances are that if you have an older R-22 unit installed that it is most likely using mineral oil. These types of oils have been used in refrigeration for decades. When HFC refrigerants began to gain popularity the use of mineral oils started to decline.

What kind of piping is used for R410A?

The same piping as R410a can be used. Both refrigerants are using synthetic oil (ether). Most of the tools used for R410a can also be used such as the gauge manifold, charge hose, charge valve, electric leak detector, vacuum pump adapter, vacuum pump, refrigerant recovery equipment and electronic weight scales.
