The Snyder Industries 4100 Gallon ASTM XLPE Heavy Duty Vertical Storage Tank (SKU 8200000N42) is a crosslinked polyethylene vertical storage tank built for demanding above-ground water and bulk liquid duty. Molded in Natural White, it stands 100 inches tall on a 120 x 120 inch footprint and carries a 1.9 specific gravity rating - a heavy-duty XLPE build that handles liquids heavier than water by weight, up to that 1.9 SG ceiling. If you have been searching for a large Snyder XLPE vertical tank, this is a true 4,100-gallon workhorse.
Will it work for your site?
Capacity is 4,100 gallons in a 120-inch nominal diameter, 100-inch-tall cylinder. Full of water, the contents weigh about 34,194 lb; at the maximum 1.9 SG rating the rated contents reach roughly 64,969 lb. Size your pad to the full 120 x 120 inch square envelope - the cylinder is 120 inches across, so the round footprint sits inside that square base - and plan the foundation around the higher weight number if you will store anything denser than water. Our concrete pad sizing guide walks through the ACI 360R-10 framework behind a proper base. Not sure this is the right volume? Run the numbers with our Tank Sizing Calculator and Tank Sizing Guide.
Fittings and access
The tank includes an 18-inch PE threaded manway for interior access and cleaning, a molded flange fitting as a defined connection point, and eight flat fitting pads spaced at 45-degree intervals around the wall. The flange gives you one pre-located outlet; the flat pads ship as blank landing surfaces you drill in the field, so each penetration needs a properly sized bulkhead fitting and gasket torqued at the pad location to get a leak-free outlet. Confirm exact fitting locations and elevations against the technical drawing on this page before you plumb the site, since those pads let you position penetrations to match your layout.
Why XLPE matters here
This is a crosslinked (XLPE) tank, not standard HDPE. Crosslinking gives the wall better resistance to environmental stress cracking and impact, which is why it earns the higher 1.9 SG structural rating and suits heavy-liquid, long-service applications. That 1.9 SG figure certifies the wall for liquid weight only - chemical suitability is a separate question you must confirm for your specific fluid, resin, and gaskets. If you are weighing this against a linear-poly tank, our guide on Snyder XLPE vs HDPE explains when crosslinking earns its keep. For fire-water and reservoir use, the rural fire-water reservoir design guide covers NFPA 22 sizing and freeze protection. The mistake to avoid: do not treat the 1.9 SG rating as a substitute for freeboard - review freeboard sizing per ASTM D1998 so you plan around usable volume, not just nominal capacity.
