The Snyder Industries 300 Gallon ASTM Black Heavy Duty Vertical Storage Tank (Snyder part 8030000N51) stands 94 inches tall on a compact 33 x 33 inch footprint, so it delivers 300-gallon rated capacity without eating up floor space. It is molded from polyethylene in black, which blocks light penetration into stored water. What separates this tank from a standard-duty vertical is the 1.9 specific-gravity rating: the wall is built to carry contents up to 1.9 times the weight of water, which is why it earns the "heavy duty" designation and holds up under demanding storage duty a lighter tank would not.
Will it work for your job?
Filled with water this tank carries about 2,502 pounds; at its full 1.9 specific-gravity rating it is built to hold up to 4,754 pounds of contents. Plan your pad for the loaded weight, not the empty shell — a level, fully supported base rated for that load is not optional on a 94-inch vertical. Because it is tall and narrow, give it a stable, wind-protected location and confirm doorway and ceiling clearances accept the 94-inch height before delivery. Note that 300 gallons is the rated capacity; ASTM D1998 verticals need freeboard, so usable working volume runs a little under nominal. Our Tank Sizing Calculator, Tank Sizing Guide, and our Snyder freeboard sizing guide per ASTM D1998 help you convert the 300 gallon rated figure into the real draw for your refill cycle.
Fittings and configuration
Per the technical drawing on this page, this vertical is configured with a flange, a 7" x 10" flat fitting, a 10" polyethylene threaded fill, a cap with 7" access, and a second flat fitting. The 10" threaded fill is the primary top fill point, the cap with 7" access serves as your inspection and hand-access opening, and the flat fitting pads are moldable locations for a bulkhead outlet or overflow. Those flat spots ship un-drilled — you drill on site and thread a bulkhead fitting with a gasket sized to your line, so match fitting and gasket material to your plumbing before you cut. Read the drawing on this page for the exact placement and orientation of each fitting, since those locations drive how your fill and outlet lines route.
