Chemical Compatibility Guides

When choosing a solenoid valve to control chemicals users need to be sure that the materials of construction are suitable for the media passing through the valve.


Here we list thousands of chemicals and the material resistance known for each, such as for Brass, 304 and 316 Stainless Steel, Various Plastics and especially the elastomer seal compounds NBR, EPDM, FKM, FFKM, PTFE and Silicone to name but a few. See the various guides we have assembled over the years which might prove helpful.
