The Enduraplas 1600 Gallon Yellow Horizontal Leg Tank (SKU THF01600Y) is a 1,600-gallon polyethylene horizontal leg tank built for transport and field haul work. It measures 130 inches long by 71 inches wide by 59 inches tall, riding on integrated legs that keep the tank stable on a trailer or skid. The bright yellow body makes liquid level easy to read at a glance, and the 1.9 specific gravity rating is the number that separates this haul tank from a plain water tank. If you have been searching for an Enduraplas horizontal leg tank to move heavy liquids, this is the size and shape that does it.
Will it work for your liquid?
The 1.9 specific gravity rating means this tank is built to carry contents up to 1.9 times the weight of water. Do the arithmetic and it sets a real payload ceiling: full of plain water the load is 13,344 pounds, and at the 1.9 SG rating the tank is rated to 25,354 pounds of contents (13,344 x 1.9 = 25,354). That is the number a hauler plans a trailer around. The 71 x 130 inch footprint tells you how it sits on your equipment, so confirm your trailer or cradle matches that span before ordering. To match this capacity and weight to your application, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. Refer to the technical drawing on this page for fitting locations and detailed dimensions.
Chemical compatibility
This is a polyethylene tank rated at 1.9 specific gravity. Before any chemical service, confirm with us whether the resin is HDLPE or XLPE, because the resin choice changes what it can safely hold. The compatibility below is drawn from the OEM chemical-resistance chart and is always concentration- and temperature-specific, so verify your exact conditions before committing. The high-demand services are the ones that will not run on standard PVC and EPDM hardware: Sulfuric Acid at 98% needs CPVC fittings with Viton gaskets, Peracetic Acid at 30% needs 316SS fittings with Aflas gaskets, and DEF at 32.5% needs 316SS fittings. A 1,600-gallon yellow leg tank carrying DEF at 32.5% with 316SS hardware is a recognized bulk-fluid haul setup, and the 1.9 SG rating gives it the payload margin to do it loaded. Several acids also require Viton gaskets rather than EPDM. Within the 1.9 SG rating, this tank pairs with these chemicals at the listed concentrations and recommended fitting and gasket materials:
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- DEF (32.5%) - 316SS 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
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC 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
- Magnesium Chloride (30%) - PVC fittings, EPDM 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 Thiosulfate (40%) - PVC fittings, EPDM 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
The matched fitting and gasket pairings matter as much as the tank itself - a Viton gasket on sulfuric acid or a 316SS fitting on DEF is not optional. See the full chemical compatibility resource for the OEM chart in detail.
Common mistake to avoid
The biggest error on a haul tank this size is treating specific gravity as a suggestion. The 1.9 SG rating is the contents-weight ceiling, not a target; pushing past 25,354 pounds of rated contents weight risks the tank and your trailer. The second mistake is putting it into chemical service before the resin is confirmed - polyethylene comes in HDLPE and XLPE, and they do not behave the same against every chemical, so verify HDLPE versus XLPE with us for your liquid first. If you are blending fertilizer in this tank, our guide on fertilizer-blend tank stratification covers the mixing protocol that keeps a load from salting out, and the overview of applicator and leg tanks for fertilizer explains the DOT and trailer scope for field use.
This tank ships LTL freight from our plant in Neche, ND, with cost quoted live to your ZIP - get your number from the Freight Cost Estimator or call 866-418-1777. With a 71 x 130 inch footprint that runs oversize on a pallet and a 1.9 SG rating that puts rated contents at 25,354 pounds, freight is quoted per destination rather than flat-rated, so the estimator gives you the most accurate figure before you order.
