The Enduraplas 1600 Gallon Green Horizontal Leg Tank is a 1,600-gallon polyethylene haul tank built for moving liquid down the road and across the field. At 130 inches long, 71 inches wide, and 59 inches tall, its long leg-tank footprint (71.0 x 130.0) keeps the center of gravity low while the molded legs nest into a frame or trailer cradle. The green polyethylene wall carries a 1.9 specific gravity rating, which is the number that decides what you can legally and safely haul in it.
Will it work for your job?
This is a transport tank, so the weight math matters more than the gallon number. Filled with water, the contents weigh 13,344 lb; at the tank's full 1.9 SG rating, the maximum rated contents weight climbs to 25,354 lb. Size your trailer, axles, and tie-downs to the heaviest product you intend to carry, not to water. At 1.9 SG this is already the top rating we stock, so there is no heavier-duty version to step up to for denser product. If you are matching this horizontal leg tank to a load or an application, the Tank Sizing Calculator and Tank Sizing Guide walk through capacity, weight, and footprint together. For mobile fertilizer and applicator use, our coverage of applicator and leg tanks for fertilizer and the Loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption explains where these tanks fall under the rules. Refer to the technical drawing on this page for fitting locations and dimensional detail before you finalize a mount.
Chemical compatibility
This tank carries a 1.9 SG rating, the highest commonly offered, which is why it covers heavy acids and brines as well as water. The resin grade is listed as HDLPE but flagged unconfirmed, so confirm whether the resin is HDLPE or XLPE with us at 866-418-1777 before committing it to chemical service. Compatibility below is drawn from the chemical-resistance data on file and is concentration- and temperature-specific; verify your exact strength and operating temperature before service.
At the listed concentrations, this tank handles acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), magnesium chloride (30%), peracetic acid (30%), phosphoric acid (85%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (<16.5%), sodium thiosulfate (40%), sulfuric acid (98%), urea solution (50%), zinc orthophosphate, and ozonated water (verified up to 10 PPM; no standalone reference page, so confirm by phone). Several entries (polyaluminum chloride, propylene glycol, sodium bisulfate, sodium bisulfite, zinc orthophosphate) are listed without a specific concentration on file, so call 866-418-1777 to confirm your strength before service.
Match the fittings and gaskets to the chemical
The most common and most expensive mistake on a chemical haul tank is bolting on the wrong fitting or gasket. The polyethylene wall is only half the system. Most of the brines and carbonates here run PVC fittings with EPDM gaskets, but the exceptions are where loads go wrong. Viton gaskets are required for hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, hydrofluosilicic acid, hydrogen peroxide, and sodium hypochlorite; peracetic acid is the one chemical here that needs Aflas, not Viton. Watch the metallurgy too: DEF (32.5%) and peracetic acid call for 316 stainless fittings, and propylene glycol and zinc orthophosphate run PP/316 stainless, not PVC, so ordering PVC plumbing for a DEF haul would be the wrong material. Check each chemical's page and the full chemical compatibility reference before you order plumbing.
This tank ships LTL freight from the Enduraplas plant in Neche, ND, with the cost quoted live to your ZIP code. Get an exact number with the Freight Cost Estimator, or call 866-418-1777 and we will quote freight, confirm the resin for your chemical, and match the right fittings and gaskets to your load before it ships.
