The Snyder Industries 4400 Gallon ASTM XLPE Black Vertical Storage Tank is a full-height bulk vertical built from crosslinked linear polyethylene (XLPE) and rated to a 1.5 specific gravity. That combination — a one-material XLPE wall carrying a 1.5 SG rating — is what lets this vertical storage tank hold heavier-than-water contents that a standard 1.0-rated HDPE tank is not built for. It stands 182 inches tall (about 15 ft 2 in) on a 90 x 90 inch footprint, which is a 90-inch (7 ft 6 in) diameter, so plan overhead clearance and pad space before it arrives.
Will it work for your site?
At 4400 gallons, a full tank of plain water weighs about 36,696 lb, and at the full 1.5 SG rating the contents can reach roughly 55,044 lb. Those are the numbers that drive your foundation: a black vertical tank this size belongs on an engineered, level concrete pad sized for the loaded 55,044 lb, not on bare soil or gravel. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm the working volume you actually need, and our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework for the base.
Fittings and access
The technical drawing on this page shows the outfitting for this XLPE vertical: a flange, an 18-inch PE threaded/vented fitting, a manway with 15-inch access, a 2–3-inch S.U.M.O. fitting, a 12 x 14 inch fitting, and a flat fitting. Confirm the drawing's fitting elevations and sizes against your plumbing before you set the tank, since relocating or adding a bottom outlet on a filled tank is not practical. The 15-inch manway access governs how you inspect, clean, and service the interior over the life of the tank. Because this is a 1.5-SG XLPE tank intended for heavier-than-water service, verify that the gasket and fitting elastomers on the flange, the S.U.M.O. fitting, and the 12 x 14 inch fitting are rated for your specific fluid before filling — the XLPE wall's chemical range is not the same as the seal materials'.
The upgrade this tank represents
The reason to buy this specific model is the 1.5 SG XLPE construction: it is the step up from an ordinary 1.0-SG HDPE vertical, giving you the wall strength to store denser fluids or a large safety margin on plain water. Spec it to your fluid's density and never load it past the rated SG. Do not treat it casually just because it looks like a standard black vertical storage tank.
This Snyder XLPE vertical ships by LTL freight from the Lincoln, NE plant, quoted live to your ZIP — get a number in seconds with the Freight Cost Estimator, or call 866-418-1777. A tank this tall and heavy is delivered on a dedicated LTL truck, so size your unloading equipment to the empty tank and confirm vertical craning or tilt-up room and site access before you order.
