Typical Acid Strengths in Water & Wastewater

HDPE, polypropylene and PVDF each handle sulfuric acid differently. See the compatibility chart for every rating.

10–75%

Mid-strength acid

HDPE, polypropylene and PVDF all rated Excellent. Viton® gaskets Excellent; EPDM and Buna-N Good.

75–93%

Concentrated acid

PVDF rated Excellent and HDPE rated Good. Polypropylene drops to Fair. Use PVDF fittings and Viton® gaskets.

93–98%

Commercial grade

Above the range of our compatibility database. Call us before storing 93–98% acid so we can review your application.

What to consider

Getting the Right Tank the First Time

Send the acid concentration, temperature, volume and fittings you need. We’ll match the resin, SG rating and gaskets.

  • Match the tank to the concentration: up to 75%, HDPE is the economical choice. From 75% to 93%, PVDF is rated Excellent and HDPE Good.
  • Double wall containment: the outer tank catches leaks and keeps fumes from spilled acid inside.
  • Fittings: Viton® gaskets are rated Excellent from 1% to 93%, and PVDF fittings are used above 75%.
  • Hardware: Hastelloy hardware; no 316 stainless above 10%.
