The Enduraplas 1900 Gallon White Horizontal Leg Tank is a transport-and-haul vessel built to move volume across the yard or down a field road. At 1,900 gallons in a horizontal leg-tank format, it carries water at roughly 15,846 lb when full, and at its 1.9 specific gravity ceiling it is rated to 30,107 lb of contents alone. That spread is the number to plan around: a dense liquid load is nearly double a water load, so size your axles, hitch, and tow vehicle to the heavy case, not the water case. Molded in Natural White polyethylene, the white wall lets an operator eyeball the liquid level at a glance while pulling a nurse load or staging fertilizer between fills.
Will it work for your job?
Measure your skid or trailer deck before you buy. This Enduraplas horizontal tank has a 71 in width by 130 in length footprint, stands 65 in tall, and the integrally molded legs keep the cylinder steady so it does not roll under braking and turning. The horizontal leg-tank shape holds the center of gravity low, which is the whole point of a tank that rides. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 1,900 gallons fits your refill cycle. Fitting sizes and locations are not listed in our spec data, so confirm the outlet, fill, and vent configuration with us before you plumb it, and review the technical drawing on this page for leg geometry and port placement.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating, the heaviest-duty rating in the line, which is why it suits dense agricultural and water-treatment liquids. Two separate questions govern any chemical job here: the 1.9 SG rating tells you the wall can carry the weight of a dense liquid, while the resin grade tells you whether the material resists permeation and stress-cracking from your chemical at your temperature. The resin grade is not confirmed in our data, so confirm it with us before you commit this tank to chemical service. Every compatibility figure below is concentration and temperature specific, so match your actual concentration and service temperature before ordering fittings or gaskets.
For the high-volume haul liquids this format is built around, this 1.9 SG tank suits DEF (32.5%, 316SS fittings, EPDM gaskets) and dense fertilizer salts like Calcium Chloride (40%, PVC, EPDM) and Magnesium Chloride (30%, PVC, EPDM). The broader list, with recommended fitting and gasket materials, includes Acetic Acid (60%, PP/PVC, EPDM), Aluminum Sulfate (50%, PVC, 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), 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). Cross-check the full chart at our chemical compatibility hub before finalizing.
The mistake to avoid
The trap on a haul tank is matching the fitting and gasket to the chemical but ignoring the SG and the resin question. Sulfuric Acid at 98% wants CPVC fittings and Viton gaskets, not the EPDM that works for the salts and glycols, and a chlorine-bearing liquid like Sodium Hypochlorite also needs Viton. Get the gasket family wrong and you have a leak on the road. Equally, do not assume this is a potable or food-grade vessel because the wall is white, which is not claimed here. Verify the resin grade and your exact concentration with us first, and review the technical drawing on this page for fitting locations and leg geometry before you spec your plumbing.
Hauling on public roads? Read our guides on 49 CFR 173.5 agricultural exemption and DOT classification for farm fleet use and on applicator and leg tanks for fertilizer, and if you are running a blended fertilizer load, see fertilizer-blend tank stratification for the mixing and field-verification protocol. This Enduraplas horizontal leg tank ships LTL freight from the plant in Neche, ND, quoted live to your ZIP. Get a number in seconds with the Freight Cost Estimator, and because shipping from North Dakota is a real cost on a tank this size, lock your delivery point before you order.
