The Snyder Industries 3900 Gallon ASTM XLPE Black Vertical Storage Tank (SKU 5190000N46) is a heavy-duty crosslinked polyethylene vertical tank rated to 1.5 specific gravity, built for bulk water and dense-liquid storage where a standard 1.0-rated tank would be under-spec'd. It measures 163" H x 90" W x 90" L and holds 3,900 gallons. Two facts decide whether this Snyder vertical tank fits your job — the black XLPE wall and the 1.5 SG rating — so start there before anything else.
Will it work for your site?
Full of water this tank carries 32,526 pounds of contents, and at its maximum rated 1.5 specific gravity it can hold up to 48,789 pounds. That contents weight — not the empty shell — drives your pad design and soil bearing, and the 90 x 90 inch footprint concentrates it, so a level, properly sized concrete pad is not optional at this scale. The 163-inch (13.6 ft) height is its own hard spec: check door and ceiling clearance for indoor installs and shipping-height permits before you commit. Note that the empty polyethylene shell is what your forklift or crane lifts at delivery, so size the offload rigging to the shell, not to the 48,789 lb loaded figure. Our Tank Sizing Calculator and Tank Sizing Guide help you match usable volume to your draw rate, and the concrete pad sizing guide walks through the ACI 360R-10 framework for a base this heavy.
Fittings and access
Per the technical drawing on this page, this vertical storage tank is configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, a 10 x 12 inch fitting/S.U.M.O., and a flat S.U.M.O. fitting. The 15-inch manway access supports inspection and cleanout, while the 10 x 12 inch and flat S.U.M.O. locations are the reinforced, self-supporting spots for your inlet and outlet plumbing. The 18-inch PE threaded/vented fitting is your vacuum-relief vent path, and it matters: a sealed 3,900-gallon tank drawing down fast can pull a vacuum and implode the wall, so keep that vent clear. Confirm every fitting size, elevation, and gasket material against the drawing before you order bulkhead or flange gaskets — thread size plus gasket is what actually seals a draw-down this large.
The mistake to avoid
Do not put a liquid heavier than 1.5 specific gravity in this tank. The 1.5 SG rating is the ceiling — water sits at 1.0 with comfortable margin, but a denser fluid pushes the wall past its structural design and shortens tank life. Match the black exterior to your application too: black blocks light and suppresses algae for outdoor water storage, which is why buyers search for it, but it also absorbs heat, so factor that into any temperature-sensitive contents. If you are sizing this for fire reserve or reuse duty, the fire-water reservoir design guide and industrial water reuse topology guide cover the sizing discipline for those use cases.
