The Snyder Industries 300 Gallon Vertical Storage Tank is a 300-gallon crosslinked polyethylene (XLPE) tank molded in black, standing 94 inches tall on a compact 33 x 33-inch round footprint. Built to ASTM standards with a 1.9 specific gravity rating, this heavy-duty vertical tank is engineered to hold dense contents well above the weight of plain water, which is what separates it from a general-purpose water-only tank. If you are sizing a fresh-water storage tank, a fire-water reservoir, or a tall-and-narrow vertical storage tank for a tight equipment pad, this is a footprint that fits where a squat tank will not.
Will it work for your site?
Fill it with water and the contents weigh about 2,502 lb; the tank body itself is rated to carry up to 4,754 lb of contents, which is the headroom the 1.9 specific gravity rating gives you for heavier-than-water liquids. That 4,754 lb figure is exactly 1.9 times the 2,502 lb water fill, so you can verify the rating against your own fluid: multiply your liquid's specific gravity by the water weight and confirm it lands under the 4,754 lb ceiling before you order. Plan your pad and anchoring around the full-contents weight, not the empty shell. At 94 inches tall on a 33-inch diameter with roughly 4,754 lb full, this is a high center-of-gravity tank, so verify overturning and tie-down anchoring on a level, load-rated pad. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 300-gallon capacity and footprint against your draw-down needs, and the concrete pad sizing framework to spec the foundation.
Fittings and outlets
Per the technical drawing on this page, the tank carries a flange, a 7" x 10" flat fitting, a 10" polyethylene threaded fill, a lid cap with a 7" access opening, and an additional flat fitting. Threaded and flat-flange fittings each need the correct bulkhead gasket or O-ring at the tank wall to seal, so confirm the gasket material against your fluid before you plumb. Check each fitting size and position against the drawing for your connections, since fill, vent, and outlet placement drive how you tie the tank in on site.
XLPE construction — and one thing to check
This is a crosslinked polyethylene tank, not standard HDPE. Crosslinking builds a tougher, more impact- and stress-crack-resistant wall, which is why XLPE is chosen for heavy-duty vertical storage. The common mistake is treating XLPE and HDPE as interchangeable: they behave differently under load and chemistry, and XLPE cannot be reworked or welded the way linear polyethylene can. If your duty is anything beyond water, read Snyder XLPE vs HDPE: when crosslinking matters. For a denser or hazardous fluid where secondary containment applies, the Snyder Captor double-wall freeboard sizing guide covers the containment math for a higher-duty companion setup.
This tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, quoted live to your ZIP — a 94-inch vertical tank rides better and quotes more accurately as a single freight shipment, so get a number before you buy with the Freight Cost Estimator or call 866-418-1777. Our team can confirm fittings, weights, and lead time and help you match this vertical storage tank to your site.
