Each chemical page shows the rating for polypropylene tanks, fittings and EPDM, Viton and Buna-N gaskets.

What to consider

Getting the Right Tank the First Time

Send the chemical, concentration, temperature and size. We’ll match the resin, specific gravity rating and fittings.

  • Built for hot baths: polypropylene is rated for continuous use up to 200°F, well above HDPE’s 120°F limit.
  • Know the exceptions: chromic acid is not recommended for polypropylene. For chromic acid and strong oxidizers, see our PVDF tanks.
  • Hydrochloric acid: rated Good for polypropylene at 20%, but only Fair at 35% to 37%. Tell us the concentration and temperature and we’ll recommend the right resin.
  • Rated fittings and gaskets: polypropylene fittings with the gasket each chemical calls for.
