The Enduraplas 1010 Gallon Black Horizontal Sump Bottom Leg Tank ships with its own frame and is built for one job: hauling liquid down the road and emptying clean. At 130 inches long, 49 inches wide, and 59 inches tall, this black polyethylene horizontal leg tank carries 1,010 gallons over a 49.0 x 130.0 inch footprint, and the sump bottom is designed to drain low so you are not leaving product behind at the end of a run. Confirm the outlet size and exact sump depth on the technical drawing on this page before you commit.
Will it work for your load?
This tank is rated to a 1.9 specific gravity, which is the number that actually governs what you can legally and safely put in it. Filled with water it holds roughly 8,423 pounds; at its full 1.9 SG rating the contents can reach about 16,004 pounds, so the frame and your transport setup have to be matched to that weight, not just to the gallon number. Black polyethylene blocks UV light, which is why horizontal leg tanks like this one are common for field-applied fertilizer, water hauling, and chemical transport. If you are sizing a fleet tank or matching capacity to a spreader or trailer, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you buy. Specific fitting sizes and locations are not listed in our spec record for this SKU, so confirm the bulkhead, vent, and outlet configuration with us before ordering; the fitting layout, sump depth, and frame dimensions are detailed on the technical drawing on this page.
Before you haul
A loaded leg tank on a trailer is a transport decision as much as a storage one. If you are running fertilizer or hauling under a farm exemption, read our guide on applicator and leg tanks for fertilizer and DOT non-roadable trailer scope and the breakdown of 49 CFR 1735 agricultural exemption and DOT classification for farm fleet use before you put this on the road, so the weight and classification are settled before the first run.
Chemical compatibility
This is an HDLPE tank (the resin code carries a question mark in our source data, so confirm HDLPE versus XLPE with us before putting it into any chemical service) rated at 1.9 specific gravity, which is a high-SG rating that opens up dense liquids most water-weight tanks cannot carry. At 1.9 SG this is already our highest-rated horizontal leg tank in this size, with no higher-SG step-up to move to, so if your fluid exceeds 1.9 SG, call before ordering. Compatibility always depends on the OEM chemical-resistance chart, which is concentration- and temperature-specific, so match your actual fluid to the chart before ordering fittings. With the right hardware this tank has documented compatibility for liquids including acetic acid (60%, PP/PVC fittings, EPDM gaskets), aluminum sulfate (50%, PVC, EPDM), calcium chloride (40%, PVC, EPDM), DEF (32.5%, 316SS fittings, 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), and ozonated water (up to 10 PPM, PVC, EPDM gaskets; no dedicated chart page, so confirm with us). Note the fitting and gasket callouts differ by chemical, and the bleach, peroxide, and strong-acid services want Viton or Aflas rather than EPDM. Match concentration and temperature before you commit, and see our full chemical compatibility reference.
The mistake to avoid
The one error that ruins a tank like this is treating the 1.9 SG rating as a license to skip the math, or mismatching the gasket to the chemical. The 1.9 rating means the tank wall can structurally handle dense product up to roughly 16,004 pounds of contents, but you still have to confirm the OEM chemical-resistance chart for your exact fluid, concentration, and temperature, and then order fittings and gaskets to match, EPDM for most salts and glycols, Viton or Aflas for oxidizers and strong acids. And because the resin code is unconfirmed in our data, do not put aggressive chemistry in this tank until we verify HDLPE versus XLPE for you.
