The Enduraplas 800 Gallon Black Horizontal Sump Bottom Leg Tank is a transport-and-haul tank built for moving dense liquid loads. It holds 800 gallons in a 94-inch-long by 60-inch-wide black polyethylene body standing 55 inches tall, with a 60.0 x 94.0 inch footprint.
Will it work for your load?
This horizontal leg tank carries a 1.9 specific-gravity rating, which is what separates a true haul tank from a water-only vessel - it is engineered to carry liquids far denser than water. Filled with water alone the tank weighs about 6,672 pounds; loaded to its maximum rated contents the tank carries up to 12,677 pounds. That is roughly 6,005 pounds of payload headroom the 1.9 rating buys you over plain water, and it works out to a maximum fluid density near 15.85 pounds per gallon, about 1.9 times the weight of water. Plug those two weights into your trailer rating, truck axle limits, and tie-downs before you load. Run the numbers against your rig with the Tank Sizing Calculator and the Tank Sizing Guide. If you are hauling fertilizer or running a non-roadable applicator setup, the guides on applicator and leg tanks for fertilizer, loaf-style portable utility tanks and the 49 CFR 173.5 ag exemption, and fertilizer-blend stratification and mixing protocol are worth reading first. Fitting and outlet configuration is not listed for this SKU - see the technical drawing on this page and confirm port sizes and locations before ordering.
Chemical compatibility
This tank is built to a 1.9 specific-gravity rating, giving it real headroom for dense chemistry. Before committing it to chemical service, confirm the tank resin with us - the pack lists it as HDLPE but unverified, and cross-link (XLPE) versus linear (HDLPE) polyethylene changes what it can safely hold, especially with acids. Work the OEM chemical-resistance chart, which is concentration and temperature specific, and remember the body, the fitting material, and the gasket are three separate compatibility calls. The simplest way to read the list below: default to PVC fittings with EPDM gaskets, step up to Viton for the strong acids and oxidizers, and move to 316SS for DEF and peracetic acid.
Most chemistries run PVC or PP fittings with EPDM gaskets: aluminum sulfate (50%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), calcium chloride (40%), magnesium chloride (30%), polyaluminum chloride, sodium thiosulfate (40%), sodium carbonate (30%), potassium carbonate (50%), potassium hydroxide (saturated), sodium bisulfate, sodium bisulfite, ethylene glycol (100%), and ozonated water (up to 10 PPM).
Step up to Viton gaskets for the strong acids and oxidizers: hydrochloric acid (37%), hydrofluoric acid (48%), and hydrofluosilicic acid (26%) on PP/PVC, phosphoric acid (85%) on PVC, hydrogen peroxide (50%) and sodium hypochlorite (<16.5%) on PVC, and sulfuric acid (98%) on CPVC. Move to 316SS fittings for DEF (32.5%) with EPDM gaskets and peracetic acid (30%) with Aflas gaskets - the only chemistry here that calls for Aflas. Zinc orthophosphate and propylene glycol run PP or 316SS with EPDM, acetic acid (60%) runs PP/PVC with EPDM, and urea solution (50%) runs PP/PVC.
The mistake to avoid
The biggest error on a 1.9 SG haul tank is matching the tank body to your chemistry but not the fittings and gaskets. Get the gasket wrong and the tank outlives the connection that fails first - the acid and chlorine families need Viton instead of EPDM, sulfuric acid needs CPVC, and DEF, peracetic acid, and zinc orthophosphate need 316SS. Always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature, and start from our full chemical compatibility reference.
