1325 Gallon Horizontal Leg Tank

The 1325 Gallon Horizontal Leg Tank from Norwesco is a polyethylene haul tank built for nurse-rig and applicator-trailer work, where liquid moves down the road instead of sitting still.Search the field for a "norwesco horizontal tank" or "horizontal leg tank" and this is the size that anchors a serious fertilizer or transfer setup: 1325 usable gallons riding on integrated legs that cradle the tank low and stable on a trailer deck.It carries a 1.5 specific gravity rating, so it is built to haul liquids heavier than water up to that density.

Will it work for your load?

Sizing comes down to weight, not just volume.Filled with plain water this tank holds roughly 11,050 lb of contents, and at its full 1.5 SG rating it is engineered to carry up to 16,576 lb of liquid.That is the number that matters for your trailer, axles, and hitch rating, not the gallon figure alone.Run your real product density through the Tank Sizing Calculator and check the Tank Sizing Guide before you spec the trailer underneath it.See the technical drawing on this page for the leg layout, outlet location, and footprint so you can confirm it sits correctly on your frame, then call 866-418-1777 to confirm the fitting and outlet configuration before you order.

Chemical compatibility

This is a 1.5 SG polyethylene tank built from high-density linear polyethylene (HDLPE).Because the resin grade drives long-term chemical resistance, confirm HDLPE versus crosslinked (XLPE) with us before you put it into dedicated chemical service.Always match readings to the OEM chemical-resistance chart for your exact concentration and operating temperature, and match the fitting and gasket material to your chemical, not just to the tank.

One callout worth pulling forward: DEF at 32.5% is a common transfer load on a tank this size, and it is the entry here that calls for 316 stainless fittings rather than PVC, with EPDM gaskets.Spec the stainless upfront.Within its 1.5 SG rating, this tank also suits liquids including acetic acid at 60% (PP/PVC fittings, EPDM gaskets), aluminum sulfate at 50% (PVC, EPDM), calcium chloride at 40% (PVC, EPDM), ferrous sulfate at 20% (PVC, EPDM), magnesium chloride at 30% (PVC, EPDM), sodium carbonate at 30% (PVC, EPDM), urea solution at 50% (PP/PVC, EPDM), and ozonated water up to 10 PPM (PVC, EPDM).

Some heavier liquids need a higher-rated 1.9 SG tank rather than this 1.5 SG model, and several of them also step up the gasket material: hydrochloric acid, hydrogen peroxide, and sodium hypochlorite move from EPDM to Viton, and peracetic acid calls for Aflas.The full list that needs a 1.5 SG tank covers 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.If your product is on that list, ask us to point you to the right tank.Start at our chemical compatibility resource to confirm before you fill.

The mistake to avoid

The trap with a leg tank this size is loading by gallons and ignoring density.At 1.5 SG your contents can reach 16,576 lb, and a trailer or DOT classification spec'd for water weight will be over before the tank is full.For agricultural and DOT-scope questions on hauling fertilizer and blended product, read our guides on Norwesco applicator and leg tanks for fertilizer and fertilizer-blend tank stratification.
