The Snyder Industries 4300 Gallon Vertical Liquid Storage Tank (SII-7421100C26) is a white polyethylene vertical storage tank built for high-volume bulk water and liquid holding. It stands 104 inches tall on a 120 x 120 inch footprint, giving you a large 4,300-gallon working volume in a stable, wide-based cylinder. Rated to a 1.9 specific gravity, this tank carries more density headroom than the typical 1.5-SG water tank, so it holds up under denser liquids while running well within its limits on plain water.
Will it work for your site?
Sizing and pad design are where large vertical tanks succeed or fail. Filled with water, this tank puts roughly 35,862 pounds of contents on your foundation, and at its full 1.9 specific gravity rating the maximum contents weight reaches about 68,138 pounds. That is a serious static load: the pad has to be flat, level, and engineered for it. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm capacity and layout, and read our concrete pad sizing guide before you pour. For rural fire-protection reservoirs, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
Why the 1.9 rating matters
That 1.9 specific gravity is the reason to choose this tank over a standard 1.5-SG water unit. It accepts liquids denser than water with real margin to spare, which is what the 68,138-pound maximum contents rating buys you. If there is any chance you will later store something heavier than plain water, this tank is covered without you re-buying a stronger vessel. When that day comes, the two checks that matter are venting and gaskets: size the vent to your maximum fill and discharge rate, and match the gasket elastomer to the actual service liquid.
The mistake to avoid
The most common error on a tank this size is treating the fitting and vent package as an afterthought. Review the technical drawing on this page, then call 866-418-1777 so we can confirm the outlet, gasket, and vent package against your service liquid before you order. On a bulk vertical, an undersized vent can pull a vacuum and deform the wall during fast draw-down, so venting has to match your fill and discharge rate. Because vapor-side wall stress is a real failure origin on large HDPE tanks, our guide on wall thickness at the vapor-saturated headspace and the ASTM D1998 sizing logic behind it is worth the read.
