The Snyder Industries 120 Gallon Vertical Liquid Storage Tank (SKU SII-1540200W94303) is a white polyethylene vertical storage tank sized for indoor and outdoor liquid storage where a compact footprint matters. It stands 41 inches tall on a 32 x 32 inch base, so it tucks into corners, utility rooms, and equipment pads without dominating the space. As a straight vertical tank from Snyder Industries, it carries a 1.5 specific gravity rating, meaning the tank wall is engineered to hold contents up to 1.5 times the density of water.
Will this white vertical storage tank work for you?
Here is the weight math that drives the decision: 120 gallons of water weighs roughly 1,001 lbs, and the 1.5 SG wall rating tops out at 1,501 lbs of contents. That 500 lb headroom is exactly what the specific gravity number buys you, as long as your liquid is no denser than 1.5 times water, the tank wall stays inside its design envelope. At 120 gallons this is one of the smaller verticals in the line, a practical pick for day tanks and point-of-use storage rather than bulk holding. To match capacity to your draw rate and refill schedule, run the numbers through our Tank Sizing Calculator or walk through the Tank Sizing Guide before you commit.
Fittings, dimensions, and the drawing
Fitting and outlet configuration for this model is defined on the technical drawing on this page, confirm it shows the connections your plumbing run needs before ordering, since outlet height and inlet placement determine how you tie the tank into your system. The 32 x 32 inch footprint and 41 inch height matter just as much for the install itself: check clearance under your fill line and over any discharge point against those dimensions before the tank ships.
The mistake to avoid
This tank is sold and rated for water and liquid storage. The most common error is over-trusting the specific gravity number, because the 1.5 SG rating covers the tank wall structurally but does not make polyethylene chemically compatible with every liquid lighter than 1.5 times water. Before you put anything other than water in it, confirm both the weight, under the 1,501 lb contents ceiling, and the chemical compatibility of polyethylene with your specific liquid. The other frequent miss is mounting: a full tank at over 1,000 lbs needs a flat, fully supported, load-rated base. Never set it on uneven ground or partial bearing.
