The Enduraplas 2500 Gallon Yellow Horizontal Leg Tank (SKU THF02500Y) is a saddle-style polyethylene tank built for hauling and field transfer, riding low on integrated legs with an 87 x 130-inch footprint and a 75-inch overall height. It carries a 1.9 specific gravity rating - the top of the polyethylene range and the number that matters most the moment you fill it with anything heavier than water. This is the horizontal leg tank to look at when you need to move a large volume of liquid fertilizer, water, or chemical between fill point and field without a separate skid.
Will it work for your load?
Capacity is a true 2500 gallons in yellow polyethylene. Full of water this tank carries 20,850 lb of contents, but the 1.9 SG rating means it is engineered to haul as much as 39,615 lb of contents at full density, so dense agricultural and chemical loads stay within the tank's design envelope. Confirm your trailer, hitch, and axle ratings against that loaded weight before you run it. The 130-inch length and 87-inch width give a stable, low center of gravity for transport, and you can verify outlet and leg placement against the technical drawing on this page. For dialing in the right size for your acreage or fleet, the Tank Sizing Calculator and Tank Sizing Guide walk through volume and weight planning.
Chemical compatibility
This is an HDLPE-style polyethylene tank rated to 1.9 specific gravity - the ceiling for poly, so there is no higher-SG version to step up to for denser service. The resin label in our data is not yet confirmed, so we will confirm HDLPE versus XLPE in writing before you commit it to chemical service; that distinction changes what you can safely store. The 1.9 SG rating means dense liquids like 98% sulfuric acid (CPVC fittings, Viton gaskets), 85% phosphoric acid (PVC, Viton), and 50% ferric chloride (PVC, EPDM) stay within the density rating. For DEF (32.5%) note the chart calls for 316SS wetted metal with EPDM, and urea solution (50%, PP/PVC, EPDM) suits exhaust-fluid and fertilizer-grade nitrogen handling. Other verified-compatible chemicals from the OEM chart include 60% acetic acid (PP/PVC, EPDM), 37% hydrochloric acid (PVC, Viton), 50% hydrogen peroxide (PVC, Viton), under-16.5% sodium hypochlorite (PVC, Viton), 50% aluminum sulfate, 40% calcium chloride, 100% ethylene glycol, polyaluminum chloride, and saturated potassium hydroxide. Peracetic acid (30%) is its own case - 316SS fittings with Aflas gaskets, not EPDM or Viton. Every figure here is concentration- and temperature-specific per the OEM chemical-resistance chart, so match the fitting and gasket material to your exact chemical and see the full chemical compatibility reference before you order.
The mistake to avoid
The common error on a hauling tank this size is treating the gallon number as the weight planning number. A leg tank at 2500 gallons full of a 1.9 SG product approaches 39,615 lb of contents - far past water weight - so size your trailer and tow vehicle to the loaded figure, not the water figure. The second mistake is sealing material. This tank ships without a pre-set fitting package, which is correct, because the chart pairs different bodies and seals to each chemical: PVC, CPVC, PP, or 316SS bodies with EPDM, Viton, or Aflas gaskets. Viton belongs on the oxidizers and acids (sulfuric, phosphoric, hydrochloric, hypochlorite, peroxide), DEF needs 316SS stainless wetted metal, peracetic acid needs Aflas, and EPDM covers most of the rest. An EPDM gasket on a Viton-spec acid is the small part that fails first. If you are spec'ing this for a non-roadable trailer fertilizer rig, the applicator and leg tank fertilizer guide and the fertilizer-blend stratification guide cover DOT scope and mixing protocol.
