The Enduraplas 2800 Gallon Green Horizontal Leg Tank is a polyethylene horizontal leg tank built to haul dense agricultural and chemical loads down the road. It measures 145 inches long by 97 inches wide and 75 inches tall and carries a 1.9 specific gravity rating, which means it is engineered to handle liquids up to 1.9 times the density of water. That headroom is the real story here: where a standard 1.5-rated leg tank tops out, this 2800-gallon enduraplas tank carries denser fertilizer blends and brines at full volume, so you move more weight per load without stepping down your fill. It is a true horizontal leg tank meant to ride in a cradle or skid frame, so the contour and integrated legs are made to be strapped down on a trailer.
Will it work for your load?
Sizing is where buyers get this wrong, so run the numbers before you fill it. Filled with plain water (SG 1.0) the contents alone weigh about 23,352 lb. At the tank's full 1.9 SG rating the contents can reach roughly 44,369 lb. That figure assumes the tank is filled to the brim with a 1.9-density liquid, which you rarely do on the road; in transport the real limiter is usually your trailer's axle rating, so size your fill to the axles, not just the shell. Because the field is what it is, note that 1.9 SG is the top rating offered for this tank and these loads, so there is no denser polyethylene option to step up to. Footprint is 97.0 x 145.0 inches, so confirm your trailer deck and any cradle fully support the horizontal body. If you are matching volume to a job, the Tank Sizing Calculator and Tank Sizing Guide walk you through capacity and weight before you commit.
Chemical compatibility
The resin record for this tank is not fully confirmed (it is recorded as HDLPE, pending verification), so before you put any chemical in it, confirm whether your unit is HDLPE or cross-linked (XLPE) - the two resins behave differently in chemical service. Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and match your fittings and gaskets to the chemical. One point that catches buyers: the fitting and gasket materials listed below are what you select and supply to match your chemical service. They are not implied to ship pre-installed on the tank. At the rated 1.9 SG, the following are compatible at the listed concentrations:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (Saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Notice that the more aggressive acids - hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sodium hypochlorite, and sulfuric - call for Viton gaskets rather than EPDM, and sulfuric at 98% wants CPVC fittings. Matching the wrong elastomer to the chemical is the most common mistake on a tank like this. See our full chemical compatibility resource and the per-chemical pages above to confirm your concentration and temperature.
Freight and ordering
This tank ships LTL freight from the Enduraplas plant in Neche, ND, and freight is quoted live to your ZIP. Because it is a large, heavy tank moving oversize LTL from a single northern plant, the delivered freight can be a real line item and it varies sharply by destination, so pull a live number with the Freight Cost Estimator before you buy.
