    What material can I use to protect surfaces against (20% concentration by weight) hydrochloric acid? Maximum operating temp is less that 50 degrees Centigrade.



  2. Hydrochloric Acid

    Hi Jessica,

    The following materials are classified as unaffected by 20% Hydrochloric acid in pumping applications:

    Epoxy resin
    Natural rubber

    Be careful with the plastics at temperatures above 25 degrees Centigrade.
