Plastic Storage Containers come standard in a natural white color for ease in liquid level viewing but are available to be custom ordered in any of our 13 colors. Are you storing a liquid and you are not sure if it’s compatible with polyethylene? Or maybe you’d like to check compatibility of our standard bulkhead fittings & gasket materials (Polypropylene & EPDM)?

View our Chemical Resistance Chart as a reference but always consult your chemical supplier if you are unsure of your chemical or liquids’s compatibility to polyethylene, polypropylene or EPDM.

The Poly-Mart 500 Gallon Plastic Storage Container is designed with 4 dome flats on the top of the tank and 4 layout flats at the base of the Container. These 8 flats are large enough to fit up to a 3″ Bulkhead Fitting and give you optimal ability to customize the fitting placement on your container! Non-Vented Lids, Siphon Tubes and larger Bulkhead Fittings are available upon request from your distributor.
