The Enduraplas 150 Gallon Yellow Horizontal Sump Bottom Leg Tank is a low-profile poly haul tank built to move dense liquids - not just water - on a trailer, skid, or truck bed. The single number that separates it from a water caddy: rated to 1.9 specific gravity, it carries roughly 2,377 lb of max-rated contents versus about 1,251 lb when filled with water alone. It holds 150 gallons in a 33 in tall body on a 41 x 46 in footprint, so the loaded center of gravity stays low for towing. Molded in yellow polyethylene with molded-in legs and a sump-style bottom, this Enduraplas horizontal leg tank is a working chemical and fertilizer hauler.
Will it work for your job?
Size the load by weight, not just gallons. Filled with water the 150-gallon capacity puts roughly 1,251 lb on the legs and the surface beneath; with a dense fertilizer blend or acid at the body's full 1.9 SG rating, max rated contents climb to about 2,377 lb. Confirm your trailer deck, hitch rating, and tie-down points can carry that loaded weight before you fill. Worth noting: 1.9 SG is already the top rating for this body, so you are buying the heaviest-rated version - there is no tougher step-up tank to chase. The 41 x 46 in footprint and 33 in height keep things stable for transport, and the technical drawing on this page shows the sump and leg geometry. If you are weighing this against other horizontal leg tank sizes, the Tank Sizing Calculator and Tank Sizing Guide match gallons and loaded weight to your equipment.
Chemical compatibility
This tank is molded in 1.9 SG-rated polyethylene; the resin family is listed as HDLPE but not yet confirmed, so for aggressive oxidizers confirm HDLPE versus XLPE construction with us before committing. The chemicals below are compatible per the OEM chemical-resistance chart at the stated concentrations - the chart is concentration- and temperature-specific, so the real decision is matching your exact strength and operating temperature, and matching gasket and fitting material to the chemical. Using the wrong gasket is how a tank that "passed" compatibility still leaks at the bulkhead, so the list is grouped by the gasket service you will be ordering.
EPDM-gasket service (the bulk - salts, glycols, DEF, urea):
- Aluminum Sulfate (50%) - PVC fittings
- Calcium Chloride (40%) - PVC fittings
- DEF (32.5%) - 316SS fittings
- Ethylene Glycol (100%) - PVC fittings
- Ferric Chloride (50%) - PVC fittings
- Ferric Sulfate (60%) - PVC fittings
- Ferrous Sulfate (20%) - PVC fittings
- Magnesium Chloride (30%) - PVC fittings
- Polyaluminum Chloride - PVC fittings
- Potassium Carbonate (50%) - PVC fittings
- Potassium Hydroxide (saturated) - PVC fittings
- Propylene Glycol - PP/316SS fittings
- Sodium Bisulfate - PVC/PP fittings
- Sodium Bisulfite - PVC/PP fittings
- Sodium Carbonate (30%) - PVC fittings
- Sodium Thiosulfate (40%) - PVC fittings
- Urea Solution (50%) - PP/PVC fittings
- Zinc Orthophosphate - PP/316SS fittings
- Ozonated Water (up to 10 PPM, no separate reference page) - PVC fittings
- Acetic Acid (60%) - PP/PVC fittings
Viton-gasket service (the strong acids, peroxide, and bleach - do not substitute EPDM here):
- Hydrochloric Acid (37%) - PVC fittings
- Hydrofluoric Acid (48%) - PP/PVC fittings
- Hydrofluosilicic Acid (26%) - PP/PVC fittings
- Hydrogen Peroxide (50%) - PVC fittings
- Phosphoric Acid (85%) - PVC fittings
- Sulfuric Acid (98%) - CPVC fittings
- Sodium Hypochlorite (<16.5% - note most industrial bleach ships at 12.5%, so confirm your strength) - PVC fittings
Aflas-gasket service:
- Peracetic Acid (30%) - 316SS fittings
Watch the two concentration-sensitive edge cases: sodium hypochlorite is rated only below 16.5% and ozonated water only up to 10 PPM. And watch the metal-fitting exceptions - DEF, peracetic acid, propylene glycol, and zinc orthophosphate call for 316SS, while sulfuric acid calls for CPVC, not the PVC that suits most of the list. See the full chemical compatibility reference and confirm your exact concentration before ordering fittings.
Freight and ordering
This tank ships LTL freight from the Enduraplas plant in Neche, ND, quoted live to your ZIP code - it is too large for parcel carriers. Get an exact number with the Freight Cost Estimator, or call 866-418-1777 and we will quote it for you. For legal-transport and tank-selection context on hauling fertilizer, see our guides on applicator and leg tanks for fertilizer, portable utility tanks and the 49 CFR 173.5 agricultural exemption, and fertilizer-blend tank stratification. Listed at the price shown above, before freight - call 866-418-1777 with any questions on fittings or fitment.
