The Norwesco 300 Gallon 45 Degree Cone Bottom Tank (SKU N-43848) is a white polyethylene cone bottom tank rated to 1.5 specific gravity, built for full-drain batching and chemical metering where you need every gallon out the bottom. It stands 56 inches tall on a 48 x 48 inch footprint, holds 300 gallons, and the steep 45 degree cone clears settling solids and viscous product far better than a shallow-cone or flat-bottom tank. This page covers what this cone bottom tank handles, how it ships, and the one spec mistake that ruins a cone tank order.
Will this cone bottom tank work for your application?
The 1.5 specific gravity rating is the number that governs what you can store. At 300 gallons, plain water fills it to about 2,502 lbs, and the tank is rated to carry up to 3,753 lbs of contents, so you have real headroom for product heavier than water up to the 1.5 SG ceiling. The 45 degree cone angle is the aggressive option in Norwesco's cone family (15, 30, and 45 degree) and is the right pick when you are settling sludge, slurries, or anything that needs to self-evacuate. Because it drains from the apex, a cone tank must sit in a stand or frame at the right height to clear your discharge plumbing and valve. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 300 gallons matches your batch volume and to plan stand height around the 56 inch tank body. If you are weighing cone angles, the 15 vs 30 vs 45 degree selection guide and the 300 gallon 45 degree buyer's guide walk through the tradeoffs.
Chemical compatibility
This tank carries a 1.5 specific gravity rating. Resin chemistry drives chemical service, so confirm whether this tank is HDLPE or XLPE and the exact resin grade with the manufacturer before committing it to a corrosive duty. Within the 1.5 SG rating, this tank suits acetic acid at 60%, aluminum sulfate at 50%, calcium chloride at 40%, DEF at 32.5%, ferrous sulfate at 20%, magnesium chloride at 30%, sodium carbonate at 30%, urea solution at 50%, and ozonated water up to 10 PPM. Match fitting and gasket materials to the chemical exactly: acetic acid and urea solution call for PP or PVC fittings with EPDM gaskets; DEF requires 316 stainless fittings with EPDM gaskets, not PVC; aluminum sulfate, calcium chloride, ferrous sulfate, magnesium chloride, sodium carbonate, and ozonated water all run on PVC fittings with EPDM gaskets. Always verify against the OEM chemical-resistance chart at your specific concentration and temperature, since both factors shift compatibility. Per-chemical detail lives at Acetic Acid, Aluminum Sulfate, Calcium Chloride, DEF, Ferrous Sulfate, Magnesium Chloride, Sodium Carbonate, and Urea Solution, with the full Chemical Compatibility Database for the rest.
The mistake to avoid: pushing past 1.5 SG
The most common cone-tank ordering error is putting a high-density chemical into a 1.5 SG tank. Heavier products including ethylene glycol, ferric chloride, ferric sulfate, hydrochloric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, peracetic acid, phosphoric acid, polyaluminum chloride, potassium carbonate, potassium hydroxide, propylene glycol, sodium bisulfate, sodium bisulfite, sodium hypochlorite, sodium thiosulfate, sulfuric acid, and zinc orthophosphate all require a 1.9 specific gravity tank, not this one. Several of those, such as hydrochloric acid, hydrogen peroxide, peracetic acid, and sodium hypochlorite, also need Viton or Aflas gaskets rather than EPDM. If your chemical is on that list, step up to a 1.9 SG cone tank before you buy. For your plumbing layout, use the dimensions on this page (56 inches tall, 48 x 48 inch footprint) and the technical drawing shown.
