Moisture-free storage and supply of compressor oils

Which oil for which A/C compressor?
Most important and simple rule: where there is PAG oil, fill up with PAG oil, where there is PAO oil, PAO oil has to be filled.
PAG oils are fully synthetic, hygroscopic oils based on polyalkylene glycol. They are used in different viscosities by many vehicle and compressor manufacturers in air conditioning systems.
PAG oils quickly attract moisture.
What could be tolerated for R 134a air conditioning systems is a real problem with R1234yf.
Because R1234yf is much more sensitive.
The solution: The professional oil system from WAECO.
The special feature is the double-walled storage container. The stable, pressureless metal container protects the oil in the laminate bag inside the container. It is also useable with other manufacturers A/C service devices thanks to a great many of adapters. 

Good to know:
Till now, oils for A/C compressors were known only as PAGs and POEs in different viscosities. Now there is a third type: PVE - a special oil for the A/C compressor in some new electric vehicles.
