The Enduraplas 1400 Gallon White Horizontal Leg Tank is a haul-ready transport tank built for moving water and rated liquids over the road on a trailer or skid frame. It holds 1,400 gallons in a natural white polyethylene body that measures 66 inches high, 70 inches wide, and 102 inches long, with the integral legs giving the horizontal design its stable, low-rolling stance. This is the white poly horizontal leg tank that farmers and applicators search for when they need a tank that sits flat on a deck and hauls a full load down the road.
Will it work for your load?
The tank carries a 1.9 specific gravity rating, the heaviest density rating offered in this horizontal leg format, so it is engineered to handle dense liquids well beyond the weight of plain water. Filled with water alone, contents weigh roughly 11,676 pounds; at the full 1.9 SG rating the tank is built to carry up to 22,184 pounds of contents. Plan your trailer, axle capacity, and tie-downs around those real numbers, not around the gallon figure. The 70 x 102 inch footprint tells you exactly how much deck space you need before you order. If you are matching tank size to a job or a spreader run, the Tank Sizing Calculator and Tank Sizing Guide walk you through capacity, weight, and footprint together. Because this is a road-haul tank, the farm-use exemption question matters as much as the weight: the 49 CFR 173.5 agricultural exemption guide and the applicator and leg tank DOT scope explainer are worth reading before you put a loaded tank on the road. See the technical drawing on this page for fitting locations and full dimensional detail.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is recorded as HDLPE in our data but not yet confirmed, so confirm HDLPE versus XLPE with us before putting it into chemical service - the distinction matters for several aggressive products. As a quick rule: most listed chemicals run PVC fittings with EPDM gaskets; aggressive acids and oxidizers need Viton, sulfuric acid needs CPVC, and peracetic acid needs 316SS with an Aflas gasket. Compatibility is always concentration- and temperature-specific, so verify your exact chemical against the OEM chemical-resistance chart before committing.
At the listed concentrations, this tank is rated compatible with acetic acid (60%) using PP/PVC fittings and EPDM gaskets; aluminum sulfate (50%), calcium chloride (40%), magnesium chloride (30%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), sodium carbonate (30%), sodium thiosulfate (40%), potassium carbonate (50%), potassium hydroxide (saturated), and polyaluminum chloride, each on PVC fittings with EPDM gaskets; ethylene glycol (100%) on PVC/EPDM; and propylene glycol and zinc orthophosphate on PP/316SS fittings with EPDM gaskets. Sodium bisulfate and sodium bisulfite run on PVC/PP fittings with EPDM gaskets.
For agricultural and fluid-transport work, the tank is rated for DEF / diesel exhaust fluid (32.5%) on 316SS fittings with EPDM gaskets and for urea solution (50%) on PP/PVC with EPDM. More aggressive products require Viton gaskets: hydrochloric acid (37%) on PVC, phosphoric acid (85%) on PVC, hydrofluoric acid (48%) and hydrofluosilicic acid (26%) on PP/PVC, hydrogen peroxide (50%) on PVC, sodium hypochlorite (under 16.5%) on PVC, and sulfuric acid (98%) on CPVC. Peracetic acid (30%) calls for 316SS fittings with an Aflas gasket. Ozonated water (up to 10 PPM) runs on PVC with EPDM, and is by confirmation only - call us to verify your service before ordering. Match fitting and gasket material exactly to the chemical, and confirm everything against the OEM chemical-resistance chart and our chemical compatibility resource.
The mistake to avoid
The costliest error on a tank like this is reading the 1.9 SG rating as permission to haul any liquid. The rating defines the structural weight ceiling - up to 22,184 pounds of contents - but it says nothing about whether the resin survives a given chemical. A product can be perfectly within the weight rating and still attack the wrong gasket or fitting material, which is why the fitting and gasket columns above are not optional. Confirm the resin grade for chemical service, match fitting and gasket material to your product, and verify concentration and temperature on the OEM chart before you fill. For dense fertilizer blends, the guide to fertilizer-blend stratification is worth a read before the spreader runs.
