The Norwesco 10 Gallon Cone Bottom Specialty Rinse Tank gives small-batch chemical and rinse operations a fully drainable vessel without committing the floor space a larger system demands. Molded from High Density Linear Polyethylene in white with a 1.5 specific gravity rating, this closed-top cone bottom tank measures 21 inches tall on a compact 13.0 x 13.0 inch footprint and holds 10 gallons. The closed-top, cone-bottom geometry lets the tank empty completely through the apex, so sediment and residual chemical clear out instead of settling in a flat sump.
Sold in a required order quantity of 2. You are buying a matched pair, which suits the side-by-side rinse and batching setups these tanks are built for. Budget and plan freight for both: 20 gallons of nameplate capacity and roughly 166 lb across the pair when full of water (2 x 83 lb), shipping together on one LTL pickup.
Will it work for your application?
Filled with water each tank carries about 83 lb, and it is rated to a maximum contents weight of 125 lb. Those two numbers are the same limit stated two ways: 125 lb divided by 10 gallons divided by 8.34 lb per gallon of water lands right at the 1.5 specific gravity ceiling. To check your media, divide your target contents weight by 10 gallons, then by 8.34, and confirm the result sits at or below 1.5. The cone bottom requires a matching stand or frame to hold the tank upright and let the drain discharge clear of the floor; see the Cone Bottom Tank Stand Compatibility Matrix along with our Tank Sizing Guide and Tank Sizing Calculator to plan support and capacity. No fittings are listed for this tank in our data, so plan the apex bulkhead, drain fitting, and gasket as separate line items rather than assuming a pre-installed outlet; the tank top fitting placement strategy guide walks through vent, fill, and drain layout that keeps batches clean, and the Norwesco cone bottom buyer's guide covers cone-angle selection across the line.
Chemical compatibility
This is an HDLPE tank with a 1.5 specific gravity rating, so it handles chemicals whose density and chemical action stay within that limit. Pair it with the right fitting and gasket material for each chemical and always confirm against the manufacturer's chemical-resistance chart, which is concentration- and temperature-specific. At the 1.5 SG rating this tank suits: Acetic Acid at 60% (details) with PP/PVC fittings and EPDM gaskets; Aluminum Sulfate at 50% (details), PVC/EPDM; Calcium Chloride at 40% (details), PVC/EPDM; DEF at 32.5% (details) with 316SS fittings and EPDM gaskets; Ferrous Sulfate at 20% (details), PVC/EPDM; Magnesium Chloride at 30% (details), PVC/EPDM; Sodium Carbonate at 30% (details), PVC/EPDM; Urea Solution at 50% (details) with PP/PVC fittings and EPDM gaskets; and Ozonated Water up to 10 PPM with PVC fittings and EPDM gaskets. All nine compatible chemicals at this SG rating use EPDM gaskets, so gasket selection is straightforward in this band; the harder Viton and Aflas elastomers only become necessary on the higher-SG chemicals below. Confirm the full list on our Chemical Compatibility Database.
Chemicals that need a higher-SG tank
Several common process chemicals exceed what a 1.5 SG tank should hold and require a 1.9 specific gravity tank instead. If your service involves Ethylene Glycol (details), Ferric Chloride (details), Ferric Sulfate (details), Hydrochloric Acid (details), Hydrofluoric Acid (details), Hydrofluosilicic Acid (details), Hydrogen Peroxide (details), Peracetic Acid (details), Phosphoric Acid (details), Polyaluminum Chloride (details), Potassium Carbonate (details), Potassium Hydroxide (details), Propylene Glycol (details), Sodium Bisulfate (details), Sodium Bisulfite (details), Sodium Hypochlorite (details), Sodium Thiosulfate (details), Sulfuric Acid (details), or Zinc Orthophosphate (details), step up to a 1.9 SG vessel; several of these acids also call for Viton or Aflas gaskets rather than EPDM. Use the Norwesco cone bottom buyer's guide and the Chemical Compatibility Database to find the 1.9 SG equivalent for your media. The biggest mistake on a tank this size is matching the SG rating to capacity but overlooking gasket chemistry, so verify both before you order.
