The Norwesco 2650 gallon elliptical leg tank in black is built for over-the-road hauling of liquid fertilizer, water, and process chemicals on a trailer or truck bed. The elliptical cross-section sits low for a stable load center of gravity, and this unit carries internal baffles to slow liquid surge when you brake, corner, and accelerate with a partial load. The molded polyethylene shell is rated to a 1.9 specific gravity, so it is built to haul dense liquids, not just water. The footprint is 88 inches wide by 122 inches long with an 82-inch height, giving you the deck dimensions you need to confirm against your trailer before you order this Norwesco black tank.
Will this tank work for your load?
Run your numbers against the weight, not just the gallons. Filled with water this tank holds roughly 22,101 pounds of contents, and at its full 1.9 specific gravity rating it is built to carry up to 41,992 pounds of liquid. Those are the contents weights you size your trailer axles, suspension, and tie-down against. Work through your gallons, product density, and total rolling weight on the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a size. See the technical drawing on this page for fitting locations and baffle layout, and confirm outlet size and location plus lid size with us before you order, since fittings on a leg tank drive your plumbing and drain-down. Fittings are confirmed per order rather than read off the drawing alone.
Chemical compatibility
This is a high-density polyethylene shell rated to 1.9 specific gravity. The resin is recorded as linear polyethylene on file, so confirm linear (HDLPE) versus cross-linked (XLPE) construction with us before you put it into chemical service, because the two resist different chemistries. Always match your fitting and gasket materials to the product, and verify every chemical against the manufacturer chemical-resistance chart at your actual concentration and temperature. Exotic fitting and gasket materials called out below (for example 316 stainless, CPVC, Viton, or Aflas) are compatibility guidance, not fittings that ship installed.
Chemicals this tank is suited to handle, with the fitting and gasket pairing for each, include Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Phosphoric Acid at 85% (PVC, Viton), Sodium Hypochlorite below 16.5% (PVC, Viton), Sulfuric Acid at 98% (CPVC, Viton), and Urea Solution at 50% (PP/PVC, EPDM), among others on the chart including ferric and ferrous sulfate, magnesium chloride, peracetic acid, the potassium and sodium salts, propylene glycol, zinc orthophosphate, and ozonated water up to 10 PPM. Confirm each against the OEM chemical-resistance chart for your concentration and temperature, and start at the chemical compatibility guide for the full table.
The mistake to avoid
The single most expensive error on a tank like this is treating the 1.9 specific gravity rating as a license to ignore total weight. A 1.9 rating means the polyethylene wall is built for dense product, but you still have to keep the loaded tank inside your trailer and axle limits, and a full load here runs close to 42,000 pounds of contents alone. The second mistake is chemical service without confirming the resin: linear versus cross-linked polyethylene matters, so settle that and your fitting and gasket materials before the first fill. For dense fertilizer blends, the layering and mixing physics matter too, covered in our fertilizer-blend tank stratification guide, and DOT trailer scope is explained in our Norwesco applicator and leg tanks for fertilizer writeup.
