The Chem-Tainer 500 Gallon HDPE Vertical Liquid Storage Tank (SKU TC6446IA) is a 64-inch-diameter, 46-inch-tall polyethylene vertical tank built for general liquid storage. It carries a 500-gallon nominal capacity in a natural-white polyethylene shell, holds 4,170 lb of water when full, and is rated to a maximum contents weight of 7,923 lb thanks to its 1.9 specific gravity wall rating. That high SG rating is the headline spec on this tank: it gives you real headroom for liquids heavier than water without re-engineering the foundation.
Will it work for your job?
This is a vertical storage tank with a 64.0 x 64.0 inch footprint, so plan your pad accordingly before it arrives. The 1.9 SG wall is rated for liquids up to 1.9 times the weight of water, and the sizing math is already done for you: 4,170 lb full of water versus a 7,923 lb maximum rated contents weight. That is roughly 3,750 lb of additional load capacity over what plain water puts in the same shell, which is the genuine advantage of a 1.9 SG tank against a standard 1.0 to 1.5 SG vertical. Use both of those weights, not the empty-tank figure, when you size your slab, ring wall, or skid. If you are still deciding between this 500-gallon vertical and another footprint, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.
The fitting and spec you should confirm
The fitting and gasket specifications are not published in this listing, so confirm the outlet size, fitting locations, and gasket material against the technical drawing on this page, or by calling us, before you plumb anything to a fixed connection or pump skid. Match your fitting and gasket elastomers to whatever you are storing, and verify the foundation against the loaded weight rather than the empty tank. For deeper background on where vertical HDPE tanks actually fail over time, the guide on HDPE tank wall thickness at the vapor-saturated headspace is worth reading, and if you are weighing brands, the Snyder vs Norwesco vs Chem-Tainer vertical comparison covers how these lines differ.
