This chart is a general guide. Chemical resistance depends on concentration, temperature and exposure time. Confirm your application with Bailiff before ordering. Don’t use welded flanges in sidewalls for nitric acid, sodium hypochlorite, sulfuric acid or other oxidizers. Need ratings for HDPE, PVDF or nylon tanks? See the full chemical compatibility database on plasticstoragetanks.com.
Choosing seals
A strong choice for most acids, caustics, alcohols and water service. Not for oils and fuels.
Best for oils, fuels and many strong acids. Avoid with ketones like acetone and with strong caustics.
Good for oils, fuels and water. Not for oxidizing acids or ketones.
Every chemical on this page is rated Excellent for polypropylene fittings. See fittings.
Send the chemical, concentration, temperature and size. We’ll match the tank and fittings and send a quote.
