Ethanol with Acetic Acid, Fermentation Mixture Compatibility with O-Ring Materials

Q: Which O-ring material is best for Ethanol with Acetic Acid, Fermentation Mixture?

Materials rated Excellent or Good for Ethanol with Acetic Acid, Fermentation Mixture include Perfluoroelastomer, Ethylene Propylene, Natural Rubber, Styrene Butadiene, Butyl. Confirm the final choice against your operating temperature and concentration.

Q: Are these Ethanol with Acetic Acid, Fermentation Mixture compatibility ratings guaranteed?

No. Ratings are guideline values at ambient temperature (~20°C) and are not a warranty. Compatibility with Ethanol with Acetic Acid, Fermentation Mixture varies with temperature, concentration, pressure and exposure time — always validate for your application.
