The Enduraplas 2200 Gallon Yellow Horizontal Leg Tank (SKU THF02200Y) is built for hauling and field-applying liquids that water-rated tanks cannot handle. Molded in yellow polyethylene with a 1.9 specific gravity rating, it measures 130 inches long by 71 inches wide and stands 72 inches tall, riding on integrated legs for transport and storage. The 1.9 SG rating is the headline number: it tells you the tank is rated to carry contents up to 1.9 times the density of water, which is why it suits dense fertilizer blends and chemical solutions rather than just clear water. At 1.9 SG this is already the densest-rated poly option for these contents, so there is no higher-density tank to step up to.
Will it work for your load?
Filled with water this tank holds roughly 18,348 pounds, but its construction is rated for contents up to 34,861 pounds at the full 1.9 SG. That headroom is what makes it an honest choice for heavy agricultural and chemical liquids. Use the difference between those two weights when you plan your axles and tongue load: a horizontal leg tank this size puts serious mass over your running gear, so size the platform to the rated contents weight, not the water weight. The 71 x 130 inch footprint sets the deck space you need. Run your load and axle numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you build. One caveat: fitting size and outlet placement are not published in our spec record for this SKU, so read them off the technical drawing on this page or confirm by phone before you plumb a fill line or mount the tank.
Chemical compatibility
This is a 1.9 SG polyethylene leg tank. The resin grade is recorded but flagged for confirmation, so verify whether it is HDLPE or XLPE with us before committing the tank to chemical service. Compatibility below is drawn from the OEM chemical-resistance chart, which is concentration and temperature specific; match the exact concentration and operating temperature for your application and choose fittings and gaskets accordingly. Chemicals this tank can carry include 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), hydrochloric acid (37%, PVC, Viton), hydrofluoric acid (48%, PP/PVC, Viton), hydrogen peroxide (50%, PVC, Viton), phosphoric acid (85%, PVC, Viton), potassium hydroxide (saturated, PVC, EPDM), sodium hypochlorite (under 16.5%, PVC, Viton), sulfuric acid (98%, CPVC, Viton), urea solution (50%, PP/PVC, EPDM), and ozonated water (up to 10 PPM, PVC, EPDM). The full chart also covers ferric sulfate, ferrous sulfate, hydrofluosilicic acid, magnesium chloride, peracetic acid (316SS fittings, Aflas gaskets), polyaluminum chloride, potassium carbonate, propylene glycol, sodium bisulfate, sodium bisulfite, sodium carbonate, sodium thiosulfate, and zinc orthophosphate. Note that polyaluminum chloride, propylene glycol, sodium bisulfate, sodium bisulfite, and zinc orthophosphate have no concentration on file in our record, so confirm yours against the OEM chart. See our full chemical compatibility resource for the per-chemical details.
The mistake to avoid
The common error on a horizontal leg tank like this is matching the gasket to the fitting instead of to the chemical. Note where the chart calls for Viton or Aflas instead of EPDM: aggressive acids and oxidizers such as hydrochloric, hydrofluoric, phosphoric, sulfuric, hydrogen peroxide, and sodium hypochlorite need Viton, and peracetic acid needs Aflas. Watch the fitting material too: sulfuric acid at 98% requires CPVC fittings, not standard PVC; DEF calls for 316SS; and peracetic acid, propylene glycol, and zinc orthophosphate call for PP or 316SS rather than PVC. Putting the wrong elastomer or the wrong fitting body at the outlet is what causes a leak, not the tank wall. And because the resin grade is flagged for confirmation, settle that question with us before you load anything more aggressive than water.
