The Norwesco 300 Gallon 30 Degree Cone Bottom Tank with Poly Stand (SKU N-43730, black) is built to fully drain aggressive liquids: the 30-degree cone floor routes contents to the 2" outlet so nothing pools, and the included poly stand holds the cone off the ground for gravity discharge. It holds 300 gallons in a rotationally molded polyethylene body rated to a specific gravity of 1.5, with a 16" lid, a 61" overall height, and a 49" diameter footprint. Empty weight is 159 lb, Norwesco lists this tank as FDA approved, and the maximum contents temperature is 120 F / 48 C. If you are cross-shopping this norwesco cone bottom tank against a 175, 310, or larger 550 gallon stand-mounted unit, the buyer's guides linked below walk the differences.
Will it hold your load
Match the tank's 1.5 specific gravity rating to what you actually store. Water at 300 gallons full weighs about 2,502 lb; at the tank's maximum rated 1.5 SG the contents reach roughly 3,753 lb, so the poly stand and your floor need to carry that fully loaded figure. Run your exact fill through the Tank Sizing Calculator and the Tank Sizing Guide before you commit. There is no fitting kit bundled here, so plumb the 2" cone outlet in the material the chemical requires, confirmed against the compatibility data below and by phone.
Chemical compatibility
This is an HDLPE polyethylene tank rated to 1.5 specific gravity. Because the resin is recorded as HDLPE with an open question, confirm HDLPE versus XLPE with us before you put it into chemical service. Compatibility is always concentration and temperature specific, so verify your exact chemical, concentration, temperature, and both fitting and gasket materials against the manufacturer chemical resistance chart (the OEM reference we key against here is the Snyder Industries HDPE/XLPE resistance data, applied to this resin). At this tank's 1.5 SG rating the following are supported: Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Aluminum Sulfate (50%, PVC, EPDM), Calcium Chloride (40%, PVC, EPDM), Ferrous Sulfate (20%, PVC, EPDM), Magnesium Chloride (30%, PVC, EPDM), Sodium Carbonate (30%, PVC, EPDM), and Ozonated Water (up to 10 PPM, PVC, EPDM). Two more clear this tank with SG margin because they only need a 1.35 rating: DEF at 32.5% and Urea Solution at 50% — but DEF requires 316SS fittings with EPDM gaskets, not the PVC used for the others, so do not plumb it in PVC.
Chemicals that need a higher-SG tank
Several common chemicals require a heavier 1.9 SG tank than this 1.5 unit and must not be stored here — and note how the gasket flips away from the EPDM used above: Ethylene Glycol (PVC, EPDM), Ferric Chloride (PVC, EPDM), Ferric Sulfate (PVC, EPDM), Hydrochloric Acid (37%, PVC, Viton), Hydrofluoric Acid (PP/PVC, Viton), Hydrofluosilicic Acid (PP/PVC, Viton), Hydrogen Peroxide (PVC, Viton), Peracetic Acid (316SS, Aflas), Phosphoric Acid (85%, PVC, Viton), Potassium Hydroxide (PVC, EPDM), Sodium Hypochlorite (under 16.5%, PVC, Viton), and Sulfuric Acid (98%, CPVC, Viton), among others. If your application is on that list, step up to a 1.9 SG tank rather than forcing this one. Start with the full Chemical Compatibility Database to confirm the pairing, and see the technical drawing on this page for cone, outlet, and stand geometry.
