The Enduraplas 1200 Gallon Yellow Horizontal Sump Bottom Leg Tank ships with an integrated frame and a sump-bottom shell that drains toward the low point, built for applicator and stationary duty where you move liquid and then need to empty it clean. It holds 1,200 gallons, measures 102 inches long by 70 inches wide by 64 inches high, and rides on a 70.0 x 102.0-inch footprint. The polyethylene shell carries a 1.9 specific gravity rating, the spec that tells you how heavy a liquid this tank is engineered to carry.
Will it work for your liquid?
Start with weight, because that is where horizontal leg tanks catch people. Filled with water (SG 1.0) the contents weigh about 10,008 lb. At the tank's full 1.9 SG rating, contents can reach roughly 19,015 lb. Size your trailer, skid, or pad and your pump for the actual density of what you are hauling, not the gallon count alone. The 1.9 SG rating governs weight only, not chemical resistance, so treat it as a structural ceiling and a freight number, not a green light for any fluid. Loaded weight and LTL freight are the two costs that surprise buyers on a tank this size, so pull a number early with the Freight Cost Estimator, then confirm fit with the Tank Sizing Calculator and the Tank Sizing Guide. This is a horizontal leg tank with a sump bottom; port count and outlet sizes are not confirmed in our records, so confirm the sump-outlet and fitting sizes with us before you order, and review the technical drawing on this page for geometry.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating, and the exact resin is not confirmed in our records, so confirm HDLPE versus XLPE with us before any chemical fill. Chemical suitability depends on that resin, your concentration and temperature, and the fitting and gasket material you spec, not on the SG rating. Treat the following as candidates to verify, each against the OEM chemical-resistance chart for your exact concentration and temperature: acetic acid (60%) with PP/PVC fittings and EPDM gaskets, aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%) with 316SS fittings, ethylene glycol (100%) and propylene glycol, ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%) with Viton gaskets, hydrofluoric acid (48%) with PP/PVC and Viton, hydrofluosilicic acid (26%) with Viton, hydrogen peroxide (50%) with Viton, magnesium chloride (30%), peracetic acid (30%) with 316SS and Aflas, phosphoric acid (85%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (under 16.5%) with Viton, sodium thiosulfate (40%), sulfuric acid (98%) with CPVC and Viton, urea solution (50%), zinc orthophosphate, and ozonated water (up to 10 PPM). Match your fitting and gasket material to the chemical, and see our full chemical compatibility resource for the complete picture.
The mistake to avoid
The number one error on a 1.9 SG-rated tank is loading a dense liquid and then under-building everything that touches it. The shell can carry the weight; your gasket and fitting material may not. Sulfuric acid at 98% needs CPVC fittings and Viton, sodium hypochlorite and hydrofluoric acid need Viton, DEF and peracetic acid need 316SS, and peracetic acid needs Aflas gaskets, not the EPDM that handles fertilizer salts fine. Pick the wrong gasket and you get a leak the tank never caused, so verify your gasket against the linked compatibility page for your specific fluid. The second mistake is skipping the resin and outlet-size confirmation above before any chemical fill.
