The Enduraplas 1400 Gallon Horizontal Leg Tank is a saddle-mounted, cylinder-on-its-side storage tank engineered for high-density liquids. It carries a 1.9 specific gravity rating - the highest-density class Enduraplas builds - so it is made to haul aggressive fluids that would overload a standard 1.0 or 1.5 SG tank. The tank comes with a 3" outlet at the base and a 16" lid up top for filling and inspection, and it is FDA approved. Published external dimensions are still being verified, so pull the leg spacing, saddle positions, and overall length straight from the technical drawing on this page before you pour a pad or build a skid.
Will it hold what you're storing?
Sizing is where a 1.9 SG tank earns its rating. Filled with plain water this 1400 gallon tank holds roughly 11,676 lb of contents. Run it at its full 1.9 specific gravity rating and the contents alone reach about 22,184 lb - nearly double the water weight. That number, not the gallon count, drives your pad, your saddle support, and your forklift or crane plan. The horizontal leg design spreads that load across saddle legs, so the surface under it has to carry the full rated weight evenly and stay dead level. Undersize the base and a heavy-density load finds the weak spot fast. If you are still choosing between capacities, run your fluid through the Tank Sizing Calculator and the Tank Sizing Guide to match gallons and weight to your application.
Chemical compatibility
Before ordering for chemical service, confirm the resin (HDLPE vs XLPE) by SKU with us at 866-418-1777 - the tank resin carries a confirmation flag, and the two materials behave differently under permeation and stress-cracking for the acids below. Compatibility comes from the Snyder Industries OEM chemical resistance chart and is concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and both fitting and gasket material before you buy. One honest note up front: nothing in this list requires a heavier tank - the 1.9 SG rating already covers every chemical shown, so there is no higher-density class to step up to.
At this rating the tank handles two broad families. The oxidizers and strong acids need Viton or harder elastomers: Sulfuric Acid (98%, CPVC fittings, Viton gaskets), Hydrochloric Acid (37%, PVC/Viton), Phosphoric Acid (85%, PVC/Viton), Hydrofluoric Acid (48%, PP/PVC, Viton), Hydrogen Peroxide (50%, PVC/Viton), and Sodium Hypochlorite (under 16.5%, PVC/Viton). Peracetic Acid (30%, 316SS fittings) is the one fluid on the chart that calls for Aflas gaskets, not Viton - flag it so you don't drop in the wrong elastomer. The salts, glycols, and ag fluids run on EPDM: Ferric Chloride (50%, PVC), Calcium Chloride (40%, PVC), Ethylene Glycol (100%, PVC), Urea Solution (50%, PP/PVC), and DEF (32.5%) - and DEF is the exception that proves the rule, because it demands 316 stainless at the outlet, not PVC. See the full chemical compatibility reference to confirm your chemical against its concentration and temperature.
The mistake to avoid
Do not spec fittings by size alone. That 3" outlet has to be built in the right material for your fluid - PVC, CPVC, PP, or 316 stainless - paired with the correct gasket. The wrong elastomer at the outlet is where a chemical tank fails first, long before the tank wall does, and DEF running through a PVC fitting instead of stainless is exactly that trap. And never read the SG rating as chemical clearance; the 1.9 number is a weight capability, not a blanket sign-off for a fluid that is not on the chart.
