Acetic Acid — Material Compatibility

Direct answer: Acetic Acid compatibility data spans 8 real published ratings across the concentration/temperature conditions tested, plus 3 additional material datasets below (seal, pump, and/or tube materials). Materials rated Excellent in at least one tested condition: PVC, Polypropylene (PP), PVDF, PFA, PTFE, Stainless Steel 316. Materials that show corrosion in at least one tested condition: PVDF — do not assume compatibility across all concentrations of this chemical.
