I have a question for everyone

In a refrigeration unit, if R22 refrigerant is used, what material are the sealing O-rings in the unit made of? In a refrigeration unit that uses R717 as a refrigerant, what material are the sealing O-rings in the unit made of?
I remember that R22 seems to be neoprene
Are these two codes both codes for Freon?
No! One is liquid ammonia, and the other is F22. In one of the refrigeration units, the refrigerant used is F22, but the sealing rings inside are made of nitrile. I’m really confused; according to the books, nitrile is only used in ammonia systems, while chloroprene is used in Freon systems. I’m totally lost now, so I’m seeking advice
Operating temperature for neoprene (sealing rings) –17 to 93； FKM fluororubber-17 to 204 ； Focus Rubber-40 to 121 ； FFKM Perfluoroether Rubber - 12.2 to 260 ； You can take a look.
Freon refrigeration coils: chloroprene rubber; ammonia refrigeration coils: neoprene rubber
Can neoprene rings be used interchangeably with fluorocarbon ones?
