The Enduraplas 2500 Gallon Green Horizontal Leg Tank is a haul-built poly tank designed to ride on a trailer or skid and carry dense agricultural and industrial liquids over the road. It measures 130 inches long, 87 inches wide, and 75 inches tall - a horizontal leg-tank design with integrated legs sized for trailer or skid mounting (refer to the drawing for leg spacing). The green polyethylene shell carries a 1.9 specific gravity rating, the spec that lets this tank safely haul fluids heavier than water - the reason buyers searching for an enduraplas horizontal leg tank in the 2500 gallon class land here.
Will it work for your load?
Capacity is 2500 gallons with a published footprint of 87.0 x 130.0 inches. Full of water the tank weighs about 20,850 lbs, and at its 1.9 SG rating it is built to carry up to 39,615 lbs of contents - run those numbers against your trailer's GVWR and axle ratings before you load. That 1.9 rating is the single most important number on this tank: it tells you the wall thickness was designed for dense fluids, so you are not buying a water tank and hoping it holds fertilizer. If you are not sure how much usable volume you actually need for your route and refill cadence, work it through our Tank Sizing Calculator and the Tank Sizing Guide first. For DOT classification and exemption questions on hauling fertilizer and utility liquids by leg and loaf tank, see our guides on applicator and leg tanks for fertilizer and loaf-style portable utility tanks under 49 CFR 173.5. We do not have fitting sizes or outlet locations on file for this SKU - call 866-418-1777 to confirm bulkhead and outlet size and lid configuration before you spec hardware, and refer to the technical drawing on this page for fitting placement.
Chemical compatibility
This tank is polyethylene with a 1.9 SG rating. The resin is recorded as HDLPE with a question mark in our data, so confirm HDLPE vs XLPE construction with us before committing the tank to any chemical service - that one fact changes what it can hold. The chemicals below come from our OEM chemical-resistance chart and are concentration- and temperature-specific; verify your exact concentration and operating temperature before filling. Each fitting and gasket pairing matters as much as the tank itself:
Acids and oxidizers: Acetic Acid (60%) with PP/PVC fittings and EPDM gaskets; Hydrochloric Acid (37%) with PVC fittings and Viton gaskets; Hydrofluoric Acid (48%) and Hydrofluosilicic Acid (26%), both PP/PVC with Viton; Hydrogen Peroxide (50%) with PVC and Viton; Phosphoric Acid (85%) with PVC and Viton; Sulfuric Acid (98%) with CPVC fittings and Viton gaskets; Peracetic Acid (30%) with 316SS fittings and Aflas gaskets; and Sodium Hypochlorite (under 16.5%) with PVC and Viton.
Salts, glycols and ag/water-treatment fluids: Aluminum Sulfate (50%), Calcium Chloride (40%), Ferric Chloride (50%), Ferric Sulfate (60%), Ferrous Sulfate (20%), Magnesium Chloride (30%), Sodium Carbonate (30%), Potassium Carbonate (50%), Potassium Hydroxide (saturated), Sodium Thiosulfate (40%), Ethylene Glycol (100%), Propylene Glycol, Polyaluminum Chloride, Sodium Bisulfate, Sodium Bisulfite, and Zinc Orthophosphate - most on PVC or PP/316SS fittings with EPDM gaskets per the chart. Ozonated Water (up to 10 PPM) is also listed compatible on PVC with EPDM (call to confirm - no dedicated page yet). For diesel exhaust fluid, see DEF (32.5%), which calls for 316SS fittings with EPDM gaskets, and Urea Solution (50%), which calls for PP/PVC fittings with EPDM gaskets. Our complete chemical compatibility reference lives on those pages.
A mistake worth avoiding
The trap on a 1.9 SG haul tank is mismatching the fitting and gasket material to the fluid. The shell may tolerate a chemical while a standard EPDM gasket will not - several fluids above require Viton or Aflas, and DEF and peracetic acid demand 316SS hardware. Spec the fittings to the fluid, not to convenience, and confirm the resin construction before chemical service. If you are blending fertilizer in this tank, the way it stratifies in transit and at rest is a real field problem; read our breakdown of fertilizer-blend tank stratification and mixing protocol before your first load.
This tank ships LTL freight from the Enduraplas plant in Neche, ND, quoted live to your ZIP. Note that it ships from this single plant, so on a 130-inch tank loaded toward 20,850 lbs full of water, freight to distant ZIPs is a real line item - run your ZIP before you commit. Get your exact rate with our Freight Cost Estimator, or call 866-418-1777 and we will size the tank, confirm the fittings for your fluid, and lock in freight to your delivery point.
