The Norwesco 1000 Gallon Horizontal Elliptical Cradle Tank (SKU N-40330) is a white polyethylene horizontal tank built for transport and mobile hauling, riding in its own elliptical cradle profile so contents stay stable on the road or on a skid. It holds 1,000 gallons, measures 90" long by 78" wide by 55" high, and weighs 284 lb empty. It ships with a 16" lid and a 2" outlet, carries an FDA-approved resin, and is rated to a specific gravity of 1.5 with a maximum temperature of 120°F (48°C). If you are sizing a hauling rig, use the footprint (78" x 90") to confirm cradle spacing before you build the frame. Buyers cross-shopping the Norwesco horizontal, elliptical, and cradle line land here for exactly this white 1000 gallon configuration.
Will it handle your load
Weight is the first thing to check on a horizontal cradle tank because the full load sits on the saddle. Filled with water this tank carries roughly 8,340 lb of contents; at its full 1.5 specific-gravity rating it is engineered for up to 12,510 lb of denser liquid. That SG headroom is what makes this an elliptical cradle tank rather than a plain water tote, but your trailer, cradle, and tie-downs have to be rated for the loaded weight you actually plan to move. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a chassis. For mobile fertilizer and utility use, our guides on DOT agricultural exemptions and non-roadable trailer scope cover how these tanks are classified on the road.
Chemical compatibility
This tank uses an unconfirmed HDLPE-or-XLPE resin rated to 1.5 specific gravity — the resin code carries a "?", so confirm HDLPE versus XLPE with us before any chemical service. Compatibility is always concentration- and temperature-specific, per the Snyder Industries OEM chemical-resistance chart, so match your exact chemical, concentration, temperature, fitting, and gasket. At or under the 1.5 rating this tank is listed for acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), urea solution (50%), and ozonated water (up to 10 PPM). Match the gasket to the chemical: EPDM for the salts, DEF, and urea; DEF also calls for 316SS fittings while most of these run PVC or PP. Worth noting for fleet buyers — DEF and urea solution only require a 1.35 SG rating, so this 1.5 SG tank carries real headroom for both.
What needs a heavier tank
Several dense chemicals exceed this tank's 1.5 rating and require a 1.9 SG-rated tank instead: sulfuric acid (98%) on CPVC with Viton, hydrochloric acid (37%), phosphoric acid (85%), ferric chloride (50%), hydrogen peroxide (50%), sodium hypochlorite / bleach (<16.5%), potassium hydroxide (saturated), ethylene glycol (100%), and peracetic acid (30%). Match the gasket accordingly — Viton for the acids and hypochlorite, Aflas for peracetic acid, EPDM for the caustics and glycols. If your chemical falls in this tier, call us and we will point you to the 1.9 SG-rated equivalent. Check any chemical against the full chemical compatibility data first.
The mistake to avoid
The common error on a horizontal cradle tank is loading a chemical heavier than water without confirming the SG rating. This tank is built to 1.5 SG; run anything denser and you are outside its structural rating no matter how compatible the resin is. Confirm both the SG number and the HDLPE-versus-XLPE resin before you fill it, and see the technical drawing on this page for fitting placement.
