This Snyder Industries 50 gallon vertical liquid storage tank is a compact white HDPE vessel carrying a 1.9 specific gravity rating and ASTM certification, on a footprint just 23 inches square. The 1.9 rating is the reason to choose this particular tank: it is built to hold liquids substantially heavier than water, so where a standard 1.0 to 1.5 rated 50 gallon tank tops out, this one is rated for dense brines and heavy solutions a water-only tank cannot legally carry. It is sized to fit a utility room, a truck bed, or a tight corner of a pump house where a larger vertical storage tank simply will not go.
Will this 50 gallon vertical tank work for your application?
The tank stands 38 inches tall on a 23 by 23 inch square footprint and holds 50 gallons. Filled with water it weighs about 417 pounds, and the wall is rated to carry contents up to 792 pounds total at the maximum 1.9 specific gravity. From the technical drawing on this page, the openings are a flange, a 10 inch polyethylene threaded opening, and a 10 inch PE threaded cap that seats on it. Read those two openings carefully before you order hardware: the 10 inch threaded opening is the manway-class fill and access port (the included cap closes it), and the flange is your actual liquid connection. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 50 gallon vertical tank matches your throughput and refill cadence.
What to get right before you order
At a 1.9 specific gravity rating the real risk is not just weight, it is the seal. A flange connection needs a gasket and a clean bolt-up to hold, and the 10 inch PE cap needs its gasket seated clean against the threaded collar. Before you plumb anything, confirm the flange gasket material is rated for the liquid you are storing, not only for water. Match your bulkhead and gasket hardware to the flange and the 10 inch threaded opening shown on the drawing so you are not adapting on the fly during installation. The second thing operators get wrong is the pad: even at water weight, 417 pounds on a 23 by 23 inch footprint concentrates real load, and a dense liquid at 1.9 SG pushes that toward 792 pounds. Set the tank on a flat, fully supporting surface, and for a permanent above-ground install size the slab properly rather than guessing.
Usable volume at high specific gravity
One more thing to size for: at a 1.9 specific gravity you do not get the full nameplate 50 gallons of usable volume. ASTM D1998 freeboard math reserves headspace, and the denser the liquid the more that matters to wall stress and the volume you can actually draw. Our walkthrough of Snyder freeboard sizing per ASTM D1998 and the companion read on HDPE wall thickness and ASTM D1998 sizing logic lay out exactly how that reserve is calculated for a Snyder ASTM-certified tank like this one.
