The Enduraplas 150 Gallon Yellow Horizontal Sump Bottom Leg Tank ships with its integrated steel frame and is purpose-built for hauling liquid loads on a trailer or truck bed. The horizontal leg-tank body measures 46 inches long, 41 inches wide, and 34 inches tall, and the legs plus sump bottom are designed to keep contents draining toward a single low point. The yellow polyethylene shell carries a 1.9 specific gravity rating, which is what makes this an enduraplas horizontal tank built as a chemical and heavy-liquid hauler rather than a water-only vessel.
Will this tank work for your load?
At 150 gallons, plain water fills out to roughly 1,251 pounds. Because the shell is rated to a 1.9 specific gravity, the tank is engineered to carry up to about 2,377 pounds of contents at full rating, which gives real headroom for dense fertilizers, acids, and heavier-than-water solutions. The way to read those two numbers: below 1.9 SG you can fill to the 150-gallon brim, and the weight ceiling only governs fluids approaching 1.9 SG. Match your fluid's specific gravity against that 1.9 ceiling before you fill, because a liquid heavier than 1.9 SG exceeds what this shell is built to hold, and an overloaded sump-bottom horizontal tank stresses the legs and frame on every road bump. The 41 x 46 inch footprint and 34-inch height keep the center of gravity low, which is exactly what you want for a horizontal leg tank riding on a moving platform. This is already a top-tier 1.9 SG hauler in this size and style, so there is no heavier-rated step-up to reach for.
Fittings and outlet
Fitting and outlet sizes are not listed in our spec data for this SKU. Confirm outlet, lid, and vent sizing against the technical drawing on this page or by phone before you order valves or plumbing, rather than assuming a size. Getting the outlet thread right the first time saves a return trip when the fittings show up.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating; the exact resin grade is not confirmed in our data, so verify HDLPE versus XLPE against the OEM chemical-resistance chart for your medium before chemical service. The chemicals below are workable in this SG-1.9 shell when paired with the correct fitting and gasket materials. Always check the manufacturer's chemical-resistance chart for your exact concentration and operating temperature before filling.
- Acetic Acid at 60% — PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate at 50% — PVC fittings, EPDM gaskets
- Calcium Chloride at 40% — PVC fittings, EPDM gaskets
- DEF at 32.5% — 316SS fittings, EPDM gaskets
- Ethylene Glycol at 100% — PVC fittings, EPDM gaskets
- Ferric Chloride at 50% — PVC fittings, EPDM gaskets
- Ferric Sulfate at 60% — PVC fittings, EPDM gaskets
- Ferrous Sulfate at 20% — PVC fittings, EPDM gaskets
- Hydrochloric Acid at 37% — PVC fittings, Viton gaskets
- Hydrofluoric Acid at 48% — PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid at 26% — PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide at 50% — PVC fittings, Viton gaskets
- Magnesium Chloride at 30% — PVC fittings, EPDM gaskets
- Peracetic Acid at 30% — 316SS fittings, Aflas gaskets
- Phosphoric Acid at 85% — PVC fittings, Viton gaskets
- Polyaluminum Chloride — PVC fittings, EPDM gaskets
- Potassium Carbonate at 50% — PVC fittings, EPDM gaskets
- Potassium Hydroxide at saturated concentration — 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 at 30% — PVC fittings, EPDM gaskets
- Sodium Hypochlorite at <16.5% — PVC fittings, Viton gaskets
- Sodium Thiosulfate at 40% — PVC fittings, EPDM gaskets
- Sulfuric Acid at 98% — CPVC fittings, Viton gaskets
- Urea Solution at 50% — PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate — PP/316SS fittings, EPDM gaskets
- Ozonated Water up to 10 PPM — PVC fittings, EPDM gaskets
The mistake to avoid is mixing fitting and gasket materials. The chlorinated and oxidizing media here — hydrochloric, hydrofluoric, hydrogen peroxide, phosphoric, sulfuric, and sodium hypochlorite — call for Viton gaskets, while DEF and peracetic acid both need 316 stainless fittings instead of PVC. Peracetic acid goes further still: it requires an Aflas gasket, a specialty seal most buyers will not have on the shelf, so order it deliberately. Spec the wrong gasket and you get a leak path long before the tank itself fails. See our full chemical compatibility resource for the OEM chart, concentration and temperature specific, and check the technical drawing on this page for fitting locations.
Freight and ordering
This Enduraplas 150 gallon horizontal leg tank ships LTL freight from the Neche, North Dakota plant, quoted live to your ZIP code. Use our Freight Cost Estimator to estimate freight to your ZIP, and the Tank Sizing Calculator or Tank Sizing Guide to confirm this is the right capacity before you buy. If you are running it on a trailer or fleet vehicle, our guides on applicator and leg tanks for fertilizer and portable utility tanks and DOT classification walk through the road-use rules, and the fertilizer-blend stratification guide covers mixing dense blends.
