Resistances to Chemicals

Chemicals and oils are available in very different qualities. Their properties vary depending on their concentration, operating temperatures, possible mix with other chemicals and the eventual presence of impurities. This is why gasket manufacturers only provide general information about the resistance of their products to various chemicals. It is therefore necessary to ask your suppliers of oils, solvents and other chemicals which materials (galvanized steel, stainless steel, etc.) and which gaskets (PE, EPDM, NBR, Silicone, etc.) they recommend. In view of the above it is also advisable that the client runs some tests in order to assess if the gaskets are suitable for the intended application. If you send us an inquiry or order, we assume that the above points have been clarified.
