The Enduraplas 100 Gallon Green Horizontal Sump Bottom Leg Tank ships with a frame and a sump-bottom design that drains toward the outlet, so the contents empty completely - the reason this 100 gallon horizontal leg tank earns its place on skid mounts, applicator rigs, and transport setups. The tank stands 28 inches tall by 41 inches wide by 46 inches long, sits on a 41.0 x 46.0 inch footprint, and is molded in green polyethylene rated to a 1.9 specific gravity. Full of water it carries roughly 834 pounds; loaded to its full 1.9 SG rating it is engineered to hold up to about 1,585 pounds of contents, so size your frame, tie-downs, and trailer to the heavier number, not the water number.
Will it work for your job?
The 1.9 SG rating is what separates this leg tank from a water-only tank: it is built for liquids substantially heavier than water. Use the listed full-water weight (834 lb) and maximum-rated weight (1,585 lb) to confirm your trailer, frame, and mounting hardware can carry a full load before you fill it. If you are matching this tank to a target volume or load, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide.
Chemical compatibility
This tank is molded polyethylene at a 1.9 specific gravity rating. Note that the resin type carries a question mark in our source data, so confirm HDLPE versus XLPE construction before committing this tank to chemical service. Compatibility, fittings, and gaskets are concentration- and temperature-specific, so always cross-check the OEM chemical-resistance chart for your exact conditions and consult our chemical compatibility resource. Because this is a sump-bottom tank, the drain outlet is the wetted low point that sees the most settled, aggressive contact - specify the outlet fitting in the listed material for your chemical (for example CPVC for 98% sulfuric acid, 316SS for DEF and peracetic acid) and seal it with the matching gasket. As a quick guide on gaskets: most listed chemicals seal on EPDM, the oxidizers and strong acids require Viton, and peracetic acid specifically requires Aflas. Based on the available data, this tank can be specified for the following chemicals at the noted concentrations with the recommended fitting and gasket materials:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (under 16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
Ozonated Water (up to 10 PPM) is also listed as compatible with PVC fittings and EPDM gaskets; a dedicated compatibility page for it is coming soon.
Mistake to avoid
The most common error on a tank like this is treating the 1.9 SG number as permission to skip the weight math. It does the opposite. At a full 1.9 SG load the contents alone can approach 1,585 pounds, far beyond the 834 pounds of plain water, so an under-built frame or trailer can fail under a dense load. The 1.9 rating is the operative limit, not a marketing number, for the heavy liquids on this list - 98% sulfuric acid and 50% ferric chloride or ferric sulfate are exactly the kind of dense chemicals that rating exists for. Confirm your support structure against the maximum-rated weight, and match the correct fitting and gasket materials to your specific chemical before service. At 1.9 SG this format already sits at the top of the polyethylene range, so if your liquid is heavier than 1.9, call us at 866-418-1777 before ordering rather than assuming it will hold.
