What oil is compatible with HFO-1234yf?
PAG oil
Four Seasons TEMP Select now offers a PAG oil that is 100% compatible with HFO-1234yf refrigerant.
Can I use HFO-1234yf?
While HFO-1234yf is considered better for the environment, it is classified as slightly flammable. Otherwise, the two refrigerants are very similar in performance. While R134a could be put into a HFO-1234yf vehicle system, it is not advisable.
Is 1234yf backwards compatible?
A/C system service intervals average a minimum of 3 years or 60,000 miles. R-1234yf requires a compatible oil for effective use. (Some PAG, PVE, and POE oils are also backward compatible with R-134a but not vice versa.) R-134a and R-1234yf should not be mixed.
Is pag 46 compatible with R-1234yf?
Fully synthetic oil based on polyalkylene glycol (PAG). For lubricating, sealing and cooling sliding and rotating parts in the refrigerant compressors and refrigerant circuits in passenger and commercial vehicle air conditioning systems. Mixes very well with type R1234yf and R134a refrigerants.
What is the difference between PAG oil and POE oil?
Polyalkylene Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems. It is more hygroscopic that either POE or PVE oils, but it does not undergo hydrolysis in the presence of water. Polyvinyl Ether (PVE) – a synthetic oil that is being used as an alternative to POE oil.
What happens if you put R134a in a R1234yf system?
The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.
Is HFO-1234yf the same as R-1234yf?
If you’re wondering what the difference is between the HFO-1234yf and R-1234yf, they are the same product; we sell the the Honeywell HFO-1234yf as either 10 or 25 lb cylinders, and R-1234yf as 8 ounce cans.
Is HFO-1234yf an A3?
HFO-1234yf has an ASHRAE (formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers ) rating of A2L (mildly flammable) and hydrocarbon refrigerant R-290 (propane) has an ASHRAE rating of A3 (highly flammable).
Does 1234yf have oil in it?
The 2016 Pilot, Civic, and Fit EV are using R-1234yf. 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.
Is 134a oil compatible with 1234yf?
Given that both refrigerants had very similar results in compatibility with elastomers as well as with metals in low water and no air, HFO-1234yf shows to be a very suitable replacement to HFC-134a in current mobile air conditioning systems.
Can you mix Pag 100 and Pag 46?
➔ 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.
Is ND oil 8 the same as Pag 46?
Yes. ND-8 is PAG 46, the same as FJC #2484.
What is HFO-1234yf refrigerant?
R-1234yf, or HFO-1234yf is soon to be one of the most popular refrigerants in the world. Making it’s debut in the early 2000’s it has quickly rose to power and will soon be the dominant refrigerant in the automotive industry.
What type of oil should I use in my 1234yf?
Refer back to my fact sheet above to see the boiling temperatures. 1234yf uses PAG oil just like R-134a but please note that it uses a different type of PAG oil. It is always safest to read the sticker labels under your hood or to consult the instruction manual before adding in any oil.
What is the difference between R-134a and 1234yf?
The operating pressures and temperatures of 1234yf are VERY similar to that of 134a. As I said before this was done intentionally to make for an easy transition. Refer back to my fact sheet above to see the boiling temperatures. 1234yf uses PAG oil just like R-134a but please note that it uses a different type of PAG oil.
What happened to 1234yf HFO?
Eventually a lot of these companies lost the war of attrition and have folded into the 1234YF HFO craze and from the pressure from the European Union. There is one company, Daimler, that is pursuing their own route into the future by developing CO2 R-744 automobile air conditioning systems.
