The Enduraplas 250 Gallon Yellow Horizontal Leg Tank (SKU THF00250Y) is a portable polyethylene tank built for hauling liquid to where the work is. It holds 250 gallons, measures 34 in. high by 47 in. wide by 55 in. long, and rides on integrated legs sized to drop into a truck bed, skid, or trailer. The yellow polyethylene carries a 1.9 specific-gravity rating, the spec that lets it haul dense agricultural and industrial liquids that would overstress a standard 1.5-SG water tank. If you have searched for an Enduraplas horizontal leg tank in the 250 gallon range, this is the size that fits the common applicator and nurse-tank footprint.
Will it work for your job
Sizing is where leg tanks catch people out. Filled with plain water, this 250-gallon tank carries about 2,085 lb. At its full 1.9-SG rating, contents alone can reach roughly 3,962 lb, so the mount, trailer, and tow vehicle must be rated for the heavier number, not the water number. In practice that ceiling works out to about 1.9 SG, or roughly 15.8 lb per gallon of contents; if your liquid sits at the top of that range, fill to the rated limit rather than brim-full. The footprint is 47.0 x 55.0 in., so confirm your bed or skid clears that before you order. Run your liquid's weight through the Tank Sizing Calculator and the Tank Sizing Guide to match the load to your rig. Factory fitting sizes and locations are not in our spec record for this SKU, so call 866-418-1777 to confirm the outlet, fill, and vent configuration before you order.
Chemical compatibility
This tank is yellow polyethylene with a 1.9 specific-gravity rating. The resin is recorded as HDLPE but is unconfirmed in our data, so verify whether your unit is HDLPE or XLPE before putting it into chemical service, since that distinction changes resistance for some liquids. Compatibility is concentration- and temperature-specific: check your exact concentration and service temperature against the OEM chemical-resistance chart before committing, and match fitting and gasket materials to the chemical, not just the tank.
Liquids compatible with this 1.9-SG tank include acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), magnesium chloride (30%), potassium carbonate (50%), potassium hydroxide (saturated), sodium carbonate (30%), sodium thiosulfate (40%), and urea solution (50%), most with PVC or PP fittings and EPDM gaskets. A handful are concentration-dependent and have no fixed grade in our data, so confirm your concentration before ordering hardware: polyaluminum chloride, propylene glycol, sodium bisulfate, sodium bisulfite, and zinc orthophosphate. DEF, propylene glycol, and zinc orthophosphate call for 316 stainless or PP wetted hardware rather than PVC. Ozonated water (up to 10 PPM) runs on PVC and EPDM but has no dedicated compatibility page yet, so confirm it by phone.
The highest-risk hardware mismatches in this set are the strong oxidizers and acids: sulfuric acid (98%) needs CPVC fittings with Viton, peracetic acid (30%) needs 316 stainless with Aflas, and hydrofluoric acid (48%) needs PP/PVC with Viton. The same Viton-gasket rule applies to hydrochloric acid (37%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), phosphoric acid (85%), and sodium hypochlorite (under 16.5%). See the full chemical compatibility tool for the complete picture.
A common mistake to avoid
The biggest error with a 1.9-SG haul tank is matching the tank but not the fittings and gaskets. The polyethylene wall may handle a chemical while a standard EPDM gasket or PVC fitting will not, which is why DEF wants 316 stainless and the strong oxidizers want Viton or Aflas. Specify the wetted hardware off the compatibility chart for your exact liquid, and confirm the resin (HDLPE vs XLPE) before chemical service. At 1.9 specific gravity this is the heaviest-rated poly leg tank in this footprint; if your liquid exceeds 1.9 SG, no higher-rated poly tank applies, so call us about alternate construction. For fertilizer and applicator-tank planning, our guides on applicator and leg tanks for fertilizer, portable utility tank DOT classification, and fertilizer-blend stratification are worth reading before your first load.
