The Enduraplas 100 Gallon Yellow Horizontal Sump Bottom Leg Tank is a polyethylene horizontal leg tank built for mobile and stationary chemical haul work where a low, stable load matters. It holds 100 gallons, measures 27 in high by 41 in wide by 46 in long, and rides on integrated legs with a sump bottom that pulls product down toward the outlet for clean draining. As a 100 gallon tank in a horizontal leg format, it sits where most farm-fleet and skid-mount jobs need it.
Will this tank work for my job
This is a 1.9 specific-gravity tank, which is the number that decides whether it survives your contents. Full of water this 100 gallon tank carries about 834 lb, but the structure is rated to hold up to 1,585 lb of contents - that headroom is what lets you run dense agricultural and water-treatment chemistries, not just water. Match the contents weight to that 1,585 lb ceiling before you fill, not the gallon number. The 41.0 x 46.0 in footprint and 27 in height keep the center of gravity low for transport, which is the whole point of the horizontal leg-tank format for field and skid-mount use. If you are sizing across capacities, run the numbers in the Tank Sizing Calculator and check loaded weights against your platform with the Tank Sizing Guide before you commit.
Chemical compatibility
This Enduraplas tank is molded polyethylene with a 1.9 specific-gravity rating. Confirm HDLPE vs XLPE on your exact unit before chemical service. Compatibility below is drawn from the OEM chemical-resistance chart and is concentration- and temperature-specific - verify your exact concentration and operating temperature against that chart before filling. The 1.9 SG rating is built for the dense salts that justify it: aluminum sulfate at 50%, calcium chloride at 40%, and magnesium chloride at 30% all run PVC fittings with EPDM gaskets, as do ferric chloride at 50%, ferric sulfate at 60%, ferrous sulfate at 20%, sodium thiosulfate at 40%, potassium carbonate at 50%, and sodium carbonate at 30%. The strong acids step up to harder elastomers: sulfuric acid at 98% (CPVC fittings, Viton gaskets), phosphoric acid at 85% (PVC, Viton), hydrochloric acid at 37% (PVC, Viton), hydrofluoric acid at 48% and hydrofluosilicic acid at 26% (PP/PVC, Viton), hydrogen peroxide at 50% (PVC, Viton), and sodium hypochlorite below 16.5% (PVC, Viton). Peracetic acid at 30% needs 316SS fittings with Aflas gaskets. For fleet and ag fluids it carries DEF at 32.5% (316SS fittings, EPDM gaskets), urea solution at 50% (PP/PVC, EPDM), acetic acid at 60% (PP/PVC, EPDM), ethylene glycol at 100% and propylene glycol, plus water-treatment feeds including polyaluminum chloride, potassium hydroxide (saturated), zinc orthophosphate, sodium bisulfate, sodium bisulfite, and ozonated water up to 10 PPM. Confirm fitting and gasket material for your exact chemistry on pages like sulfuric acid, sodium hypochlorite, ferric chloride, hydrochloric acid, DEF, and the full chemical compatibility index.
The mistake to avoid
The expensive error on a leg tank like this is treating the 1.9 SG rating as a license to ignore fitting and gasket material. The polyethylene shell may tolerate a chemical while a stock EPDM gasket or PVC bulkhead does not - sulfuric acid wants CPVC and Viton, peracetic acid wants 316SS and Aflas, and DEF wants 316SS. The tank ships without chemical-service fittings installed, so select your bulkheads, outlets, and gaskets from the compatibility table for your specific fluid rather than assuming the named PVC, Viton, or 316SS parts come with it. The second mistake is filling to the gallon mark with a dense fluid; confirm your contents weight stays under the 1,585 lb limit before you fill.
This 100 gallon Enduraplas horizontal leg tank ships LTL freight, quoted live to your ZIP from the nearest stocking plant - for this tank that is Neche, ND. Because the loaded weight up to 1,585 lb drives the handling, confirm your contents weight first, then pull a real number with the Freight Cost Estimator.
