Following is a list of chemicals that are suitable for pump components such as "O" rings, diaphragms etc.
This list is not an indication that a pump containing these materials makes the pump suitable for these chemicals (most pumps as an example must not pump inflammable liquids)
For more specific information see the chemical resistance guide.
