Snyder Industries 400 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

The Snyder Industries 400 Gallon Vertical Storage Tank is built from crosslinked linear polyethylene (XLPE) in black, rated to a 1.9 specific gravity — a heavy-duty wall spec that carries dense contents many standard-density HDPE vertical tanks are not rated for. At 62 inches tall on a 45 x 45 inch footprint, it holds 400 gallons in a compact vertical column, which is why it turns up in searches for a black Snyder XLPE vertical storage tank when floor space is limited but capacity still matters.

Will it work for your site?

Filled with water this tank carries about 3,336 pounds; loaded to its full 1.9 SG rating it can carry up to 6,338 pounds of contents. Plan your pad for the heavier of those two numbers depending on what you store — a 45 x 45 inch footprint concentrates real load, so a level, engineered base matters. Our Tank Sizing Calculator and Tank Sizing Guide help you match drawdown volume to demand, and because 400 gallons is a nominal figure, the freeboard and usable-volume guide shows how much you can actually draw. For a poured base, the concrete pad sizing framework walks through the ACI thresholds for a tank this weight.

Fittings and configuration

Per the technical drawing on this page, this tank is built with a flange, an 18-inch polyethylene threaded and vented lid, a 6-inch by 8-inch fitting, and a manway for access. Match your bulkhead or valve thread to the 6-inch by 8-inch fitting and confirm the flange size before ordering plumbing hardware — the vented lid and the flange determine how you fill, breathe, and draw the tank, and every fitting location and elevation is called out on the drawing. Verify all four features against that drawing before you plumb.

XLPE vs HDPE and heavy-duty use

The crosslinked wall is the reason to choose this model over a standard vertical tank. Crosslinking builds impact and environmental-stress-crack resistance into the wall, which is what the 1.9 SG rating reflects — and 1.9 is the ceiling here, so this is the heavy-duty option rather than the standard-density one. If you are weighing this against a standard-density tank, the Snyder XLPE vs HDPE guide explains exactly when the crosslinked wall earns its place. For fire-water or reserve storage on a rural site, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
