The Enduraplas 1010 Gallon Yellow Horizontal Sump Bottom Leg Tank (SKU THD01010Y) is a transport-rated polyethylene leg tank with a 1.9 specific gravity rating, which is the spec that defines it: most poly haul tanks top out at 1.0 or 1.5, and 1.9 sits at the top of the polyethylene range. It measures 130 inches long by 49 inches wide by 58.5 inches high, with a 49.0 x 130.0 inch footprint. The horizontal profile and molded support legs let it ride low and stable on a trailer or skid, and the sump bottom drains toward a low point for cleaner emptying and cleanout between loads. That low, wide stance is exactly what most buyers searching for an Enduraplas horizontal leg tank for chemical or fertilizer hauling are after.
Will it work for your load?
Capacity is 1,010 gallons. Full of water the tank carries roughly 8,423 pounds of contents; rated to its full 1.9 specific gravity, it is engineered to hold up to 16,004 pounds, nearly double a plain water fill. That headroom is the point of the 1.9 rating: it lets this tank carry dense fertilizer blends and heavy acids that would over-stress a 1.0 or 1.5 tank. The gating check is simple, so confirm your contents' specific gravity does not exceed 1.9 (about 15.8 lb per gallon). Then size the trailer, axles, and tie-downs to the loaded weight, not the empty tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to check the loaded weight against your equipment before you order. The outlet size and bulkhead fitting configuration are not yet specified for this listing, so call 866-418-1777 to confirm the fittings before ordering.
Chemical compatibility
This is a polyethylene tank with a 1.9 specific gravity rating. The resin is recorded as HDLPE but is not yet confirmed, so verify the resin type with us before putting it into chemical service. The 1.9 rating gives this tank a wide compatible range. Confirmed chemicals from the chemical-resistance chart include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), magnesium chloride (30%), peracetic acid (30%), phosphoric acid (85%), polyaluminum chloride, potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium hypochlorite (under 16.5%), sodium thiosulfate (40%), sulfuric acid (98%), urea solution (50%), zinc orthophosphate, and ozonated water (up to 10 PPM). Fitting and gasket materials are specified per chemical: most salts and bases use PVC fittings with EPDM gaskets, while the aggressive oxidizers and strong acids require Viton gaskets and harder fitting materials, such as CPVC with Viton for sulfuric acid, 316 stainless with EPDM for DEF, and 316 stainless with Aflas for peracetic acid. The mistake to avoid is matching the tank wall but ignoring the fittings and gaskets, since the seals fail long before the polyethylene does. Always confirm against the chemical-resistance chart for your exact concentration and temperature, and see our full chemical compatibility reference before you commit. At 1.9 SG this tank is already near the top of the poly range, so contents above 1.9 specific gravity are not served by a higher-rated stock poly tank; call us for a custom or alternate-material solution rather than expecting an upgrade SKU.
Freight
This tank ships LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP code. Because freight on a 130-inch horizontal tank depends entirely on your delivery location and accessorials, we quote it separately rather than burying it in the list price. Get a real number with our Freight Cost Estimator. For DOT classification and non-roadable trailer scope on fertilizer hauling, 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 (where the sump bottom helps you fully drain and re-mix a blend that has stratified). Questions on fit, fittings, or freight? Call 866-418-1777.
