Refrigeration compatibility with seals

I've been doing this to find the best seals for my project but then figured it might be usefully for others as well so here she goes:

R - 290,
HydroCarbon: PolyAmide (PA) Nylon; Nitrile Rubber; ChloroFluoroCarbons (FKM) (Viton-tm).

R - 600-a,
HydroCarbon: PolyAmide (PA) Nylon; Nitrile Rubber; ChloroPrene (CR); ChloroFluoroCarbons (FKM) (Viton-tm).

R - 152-a
PolyAmide (PA) Nylon; ChloroPrene (CR); EthylenePropylene (EPDM)

R - 022--
PolyAmide (PA) Nylon; EthylenePropylene (EPDM)

All thees synthetics are the supposed Ideal materials that will not overly swell or be permeable to the refrigerant.

Please add to this list.

Interesting to note thus far all most every one is compatible with PolyAmide Nylon as a seal & the Hydrocarbons with Nitrile rubber.
