The Enduraplas 150 Gallon Black Horizontal Sump Bottom Leg Tank is built for hauling liquid down field rows, between job sites, and across the yard on a trailer or skid. It holds 150 gallons in a black polyethylene tank that measures 34 inches high, 41 inches wide, and 46 inches long, with molded legs and an integrated frame that keep it stable when it is moving. The sump bottom drains the tank fully so you are not chasing a last few gallons of product, and the horizontal leg-tank geometry keeps the center of gravity low for transport.
Will this Enduraplas horizontal leg tank work for your job?
This is a 1.9 specific-gravity-rated tank, a heavy-duty rating that lets it carry dense agricultural and industrial liquids, not just water. On water, a full 150 gallons weighs about 1,251 pounds; at the tank's maximum 1.9 SG rating, the contents can weigh up to 2,377 pounds, so size your trailer, skid, and tie-downs to the loaded weight you actually plan to haul, not the empty tank. You can pin down that loaded weight against your delivery ZIP with our Freight Cost Estimator before you commit. The footprint is 41.0 x 46.0 inches, which is worth checking against your trailer deck or truck bed before you order. If you are matching tank size to a spray rate or fill schedule, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide. For more on how leg and applicator tanks fit DOT and trailer use, see our guide on applicator and leg tanks for fertilizer and the breakdown of portable utility tanks under 49 CFR 173.5. Hauling dense fertilizer blends adds one more wrinkle: a moving tank can stratify and salt out, so review the field methods in our guide on fertilizer-blend tank stratification before you run off spec.
Chemical compatibility
This tank is molded from polyethylene with a 1.9 specific-gravity rating. The resin is listed as HDLPE pending confirmation, so confirm HDLPE versus XLPE with us before putting this tank into chemical service. Polyethylene at a 1.9 SG rating handles a wide range of agricultural and water-treatment chemicals, and the correct fitting and gasket materials matter as much as the tank itself. Based on the OEM chemical-resistance data, this tank can be matched to liquids including acetic acid (60%) with PP/PVC fittings and EPDM gaskets, aluminum sulfate (50%) with PVC fittings and EPDM gaskets, calcium chloride (40%) with PVC fittings and EPDM gaskets, DEF (32.5%) with 316SS fittings and EPDM gaskets, ethylene glycol (100%) with PVC fittings and EPDM gaskets, ferric chloride (50%) with PVC fittings and EPDM gaskets, ferric sulfate (60%) with PVC fittings and EPDM gaskets, ferrous sulfate (20%) with PVC fittings and EPDM gaskets, hydrochloric acid (37%) with PVC fittings and Viton gaskets, hydrofluoric acid (48%) with PP/PVC fittings and Viton gaskets, hydrofluosilicic acid (26%) with PP/PVC fittings and Viton gaskets, hydrogen peroxide (50%) with PVC fittings and Viton gaskets, magnesium chloride (30%) with PVC fittings and EPDM gaskets, peracetic acid (30%) with 316SS fittings and Aflas gaskets, phosphoric acid (85%) with PVC fittings and Viton gaskets, polyaluminum chloride with PVC fittings and EPDM gaskets, potassium carbonate (50%) with PVC fittings and EPDM gaskets, potassium hydroxide (saturated) with PVC fittings and EPDM gaskets, propylene glycol with PP/316SS fittings and EPDM gaskets, sodium bisulfate with PVC/PP fittings and EPDM gaskets, sodium bisulfite with PVC/PP fittings and EPDM gaskets, sodium carbonate (30%) with PVC fittings and EPDM gaskets, sodium hypochlorite (under 16.5%) with PVC fittings and Viton gaskets, sodium thiosulfate (40%) with PVC fittings and EPDM gaskets, sulfuric acid (98%) with CPVC fittings and Viton gaskets, urea solution (50%) with PP/PVC fittings and EPDM gaskets, zinc orthophosphate with PP/316SS fittings and EPDM gaskets, and ozonated water (up to 10 PPM) with PVC fittings and EPDM gaskets. Concentrations and gasket choices are concentration- and temperature-specific, so verify your exact service against the OEM chemical-resistance chart and our chemical compatibility reference before ordering fittings.
The mistake to avoid on this tank
The most common error on a heavy-haul tank like this is matching the fitting and gasket to the tank instead of the chemical. The 1.9 SG polyethylene shell tolerates aggressive liquids, but a wrong gasket fails first: hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, hydrogen peroxide, sodium hypochlorite, and sulfuric acid all need Viton, peracetic acid needs Aflas, and DEF needs 316SS hardware rather than standard PVC. Sulfuric acid is the one fitting exception in the whole chart: at 98% it needs CPVC fittings, not plain PVC. Note too that DEF (32.5%) and similar urea-based fluids depend on clean, dedicated 316SS hardware to stay in spec. The second mistake is forgetting the resin question: because the resin is HDLPE pending confirmation, do not assume cross-link (XLPE) chemical performance until we confirm the exact resin for your chemical.
