Chem-Guide for recommendations regarding chemical compatibility of material exposure to specific media and media-treatment
additives. The NIBCO Chem-Guide is a general guide on the topic of chemical compatibility and is by no means an exhaustive resource on the subject. Ultimately, proper material
selection is the responsibility of the installer and/or end-user, taking into account all aspects of a system’s design and intended use.
