According to
http://www.oringswest.com/
Methanol will work with EPDM, Neoprene (Chloroprene), Fluorosilicone and silicone, but NOT nitrile (buna-N) nor Viton.
Water will work with Viton and Neoprene, but only "fairly", which they mean as "Static usually OK". Otherwise will work with all above materials.
Which leaves:
EPDM
Neoprene (Chloroprene)
Fluorosilicone
Silicone
and
Polyurethane
Teflon

Now let's take out Polyurethane, for it's poor acid resistance.
