The Enduraplas 150 Gallon Green Horizontal Leg Tank is a 150-gallon polyethylene haul tank built to ride on a trailer, skid, or pickup bed and move dense liquid where you need it. It measures 28 inches tall, 41 inches wide, and 46 inches long, with a 41.0 x 46.0 inch footprint and a low 28-inch loaded height that keeps it under most cab-height sightlines and drops cleanly onto a utility trailer. The molded legs set the bolt-down pattern and keep the center of gravity low when the tank is full and in motion, which is the whole reason to run a horizontal leg tank instead of an upright vertical. If you are weighing capacity against trailer size, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide before you buy.
Will this tank handle my load?
Filled with water, this tank carries about 1,251 pounds. At its 1.9 specific gravity rating, the maximum rated contents weight climbs to roughly 2,377 pounds, about 1,126 pounds more than water, so size your trailer, axles, and tie-downs to the heaviest liquid you plan to haul, not just to water. That 1.9 SG rating is what separates this tank from a plain water-only horizontal: it is built to carry the dense agricultural and chemical liquids, including DEF, fertilizer blends, and treatment chemistry, that would overstress a lighter-rated tank. See the technical drawing on this page for fitting and port locations before you plumb it.
Chemical compatibility
This is a polyethylene tank carrying a 1.9 specific-gravity rating. Before chemical service, confirm whether your application needs HDLPE or XLPE, because resin chemistry changes long-term resistance, and match the fitting and gasket materials to the liquid and its concentration, not to the tank. Always verify against the OEM chemical-resistance chart, which is concentration- and temperature-specific, and review our chemical compatibility resources for the exact chemical you intend to store. The table below pairs each compatible liquid in this tank's rating with the recommended fitting and gasket material.
| Chemical | Concentration | Fitting | Gasket |
|---|---|---|---|
| Acetic Acid | 60% | PP/PVC | EPDM |
| Aluminum Sulfate | 50% | PVC | EPDM |
| Calcium Chloride | 40% | PVC | EPDM |
| DEF | 32.5% | 316SS | 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 |
| Magnesium Chloride | 30% | PVC | EPDM |
| 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 |
| Ozonated Water (chart only) | up to 10 PPM | PVC | EPDM |
The mistake to avoid
The most common error on a 1.9 SG leg tank is matching the fittings and gaskets to the tank instead of to the chemical. The harshest liquids in the table, such as sodium hypochlorite, sulfuric acid, and peracetic acid, call for Viton or Aflas gaskets and CPVC or 316SS fittings, not the EPDM used on milder salts and glycols. Pairing an EPDM gasket with bleach or strong acid is how a brand-new tank starts weeping at the bulkhead. Confirm the resin and the exact concentration against the OEM chart before you order hardware, and remember the Ozonated Water entry is chart-only and has no dedicated page. This is an Enduraplas horizontal leg tank for 150-gallon haul duty, and getting the plumbing right the first time is what keeps it in service.
