The Enduraplas 3000 Gallon Yellow Horizontal Sump Bottom Leg Tank is a transport-and-transfer vessel for dense agricultural and industrial liquids, built to ride on a skid or non-roadable frame rather than sit on a stand. It holds 3,000 gallons in a 130-inch-long by 87-inch-wide horizontal body that stands 93 inches tall, riding on integral legs with a sump bottom that drains toward a low point for clean offloading. The yellow polyethylene tank carries a 1.9 specific gravity rating, which is what makes this an Enduraplas horizontal leg tank for fertilizer and chemical service rather than a plain water caddy. If you are sizing a 3000-gallon horizontal leg tank for liquid fertilizer or chemical transfer, this is the configuration that fits a non-roadable trailer or skid frame.
Will it work for your load?
The number that decides everything here is the 1.9 specific gravity rating. Full of plain water, this tank carries 25,020 pounds of contents; at its maximum rated specific gravity it is built to carry up to 47,538 pounds of liquid. That spread is the whole point of a 1.9-rated wall: you can haul a dense liquid fertilizer or a heavy chemical blend, not just water. Use the Tank Sizing Calculator and the Tank Sizing Guide to match your liquid's density against that weight ceiling before you commit a frame to it, because the skid, axles, and tie-downs all have to be rated for the full loaded weight of the densest liquid you intend to run. Plan your deck space around the 87 x 130 inch footprint, and see the technical drawing on this page for the full dimensional layout.
Chemical compatibility
This is a yellow polyethylene tank rated to 1.9 specific gravity. The resin grade is recorded as HDLPE in our data but carries an open question, so confirm whether your specific build is HDLPE or XLPE before putting it into chemical service: cross-linked and high-density linear polyethylene do not share an identical chemical-resistance profile. Call us at 866-418-1777 to verify the resin. Against the OEM chemical-resistance chart, which is always concentration- and temperature-specific, this tank is listed compatible with the chemicals below when fitted with the matching hardware. Two entries break the default PVC/EPDM pattern and deserve extra attention: sulfuric acid at 98% needs CPVC fittings with Viton gaskets (not PVC), and DEF at 32.5% needs 316 stainless fittings, not plastic.
EPDM gasket family (most salts, glycols, and bases): aluminum sulfate 50%, calcium chloride 40%, ethylene glycol 100%, ferric chloride 50%, ferric sulfate 60%, ferrous sulfate 20%, magnesium chloride 30%, polyaluminum chloride, potassium carbonate 50%, potassium hydroxide (saturated), sodium bisulfate, sodium bisulfite, sodium carbonate 30%, sodium thiosulfate 40%, urea solution 50%, and ozonated water up to 10 PPM (all on PVC or PVC/PP fittings). Acetic acid 60% runs PP/PVC fittings with EPDM.
Viton gasket family (acids and oxidizers): hydrochloric acid 37% (PVC), hydrofluoric acid 48% (PP/PVC), hydrofluosilicic acid 26% (PP/PVC), hydrogen peroxide 50% (PVC), phosphoric acid 85% (PVC), and sodium hypochlorite below 16.5% (PVC).
Stainless and specialty fittings: peracetic acid 30% takes 316SS fittings with Aflas gaskets; propylene glycol and zinc orthophosphate run PP/316SS with EPDM. Match the fitting and gasket material to your chemical, verify your exact concentration and temperature against the manufacturer's chart, and check our full chemical compatibility reference before you order hardware.
The mistake to avoid
The error that ruins a tank like this is treating "polyethylene" as one material and bolting the same gasket onto every port. The salts and glycols run fine on EPDM, but the acids and oxidizers above demand Viton, peracetic acid needs Aflas, and two of these chemicals will not tolerate plastic fittings at all (98% sulfuric needs CPVC, DEF needs 316 stainless). Confirm the resin grade and pull the correct fitting and gasket material for your specific chemical before the first fill, not after a leak. For the regulatory side of moving these tanks, read our guides on applicator and leg tanks for fertilizer, DOT classification for farm-fleet portable tanks, and fertilizer-blend tank stratification.
