The Norwesco 2650 Gallon Elliptical Leg Tank in White carries a heavy chemical-service rating and the geometry to haul it down the road. This polyethylene tank is rated to 1.9 specific gravity, and the baffles damp the surge that wants to throw a partially full tank around on turns and stops. At 82 inches tall on an 88 by 122 inch elliptical footprint, this Norwesco elliptical leg tank sits low and wide for a 2650-gallon haul, which is exactly what a baffled leg tank should do.
Will this tank work for your job?
Filled with water, this tank carries 22,101 pounds. At its full 1.9 specific-gravity rating it is built to hold up to 41,992 pounds of contents, so the structure is designed around dense liquids, not just water. That 1.9 rating sits near the top of the polyethylene range and covers every chemical on the compatibility list below at the densities shown, so you are not under-rated on density for any listed service. Size the trailer, axles, and tie-downs to the loaded weight you actually plan to run, not the empty tank. If you are matching this to a target volume or a chemical density, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. The 88 by 122 inch footprint is the number to check against your trailer deck and skid frame. Outlet, fill-opening, and vent provisions are not published in this listing, so call 866-418-1777 to confirm available fitting and bulkhead configurations before you order.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The resin is listed as HDLPE, but that designation carries a question mark in our records, so confirm HDLPE versus XLPE with us at 866-418-1777 before putting this tank into chemical service - the resin determines which chemicals it will safely hold. The chemicals below are drawn from our chemical compatibility reference, which is concentration- and temperature-specific; always match your exact concentration and service temperature before ordering. One more thing the list does not say outright: this is the vessel only. The fitting and gasket materials shown for each chemical are what your plumbing must be, sourced separately to match the service.
Compatible service includes acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, EPDM), ethylene glycol (100%, PVC, EPDM), ferric chloride (50%, PVC, EPDM), ferric sulfate (60%, PVC, EPDM), ferrous sulfate (20%, PVC, EPDM), hydrochloric acid (37%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrofluosilicic acid (26%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), magnesium chloride (30%, PVC, EPDM), peracetic acid (30%, 316SS, Aflas), phosphoric acid (85%, PVC, Viton), polyaluminum chloride (PVC, EPDM), potassium carbonate (50%, PVC, EPDM), potassium hydroxide (saturated, PVC, EPDM), propylene glycol (PP/316SS, EPDM), sodium bisulfate (PVC/PP, EPDM), sodium bisulfite (PVC/PP, EPDM), sodium carbonate (30%, PVC, EPDM), sodium hypochlorite (under 16.5%, PVC, Viton), sodium thiosulfate (40%, PVC, EPDM), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), zinc orthophosphate (PP/316SS, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). Note how the fitting and gasket material changes with the chemical - the bleach and acid services move to Viton, peracetic acid needs Aflas, and the DEF and zinc orthophosphate lines call for 316 stainless. Match those to your spec, and see the full chemical compatibility reference and the technical drawing on this page for fitting locations.
The mistake to avoid
The expensive error on a high-density haul tank is under-rating the load. People see "2650 gallon" and budget around 22,101 pounds of water, then run a 1.9 specific-gravity product and ask the trailer to carry up to 41,992 pounds. Verify your contents weight at your actual density, and confirm the resin before chemical service. If you are blending fertilizer, watch for stratification - dense components settle and salt out, so read our guide on fertilizer-blend tank stratification and the field checks that catch a stratified tank before the spreader runs off spec. For DOT classification and the non-roadable trailer scope on applicator and leg tanks, see our breakdown of Norwesco applicator and leg tanks for fertilizer and the related notes on portable utility tanks and the 49 CFR 173.5 agricultural exemption.
