The Snyder Industries 405 Gallon Used Oil Containment Tank is a yellow, high-density linear polyethylene tank built to hold spent oil and similar dense fluids, with a level gauge that gives you an at-a-glance read on how full it is. It stands 73 inches tall on a 48 by 48 inch square footprint, so it tucks into a maintenance bay or fluid-storage corner without sprawling. This is a closed yellow shell - you cannot see the liquid line through the wall - so the gauge is doing real work, and it ships LTL from the Snyder plant in Chowchilla, CA, quoted live to your ZIP (run your number on the Freight Cost Estimator before you commit, since a tank this size is a real freight item to most of the country). The defining number here is the 1.9 specific-gravity rating: this shell is engineered for genuinely heavy contents, not just water.
Will it hold your fluid?
At 405 gallons, the tank carries roughly 3,378 pounds when filled with plain water. Because the HDLPE wall carries a 1.9 specific-gravity rating, it is rated for contents up to about 6,418 pounds total - which is exactly why it suits a dense waste-oil stream rather than topping out at the weight of water. Match your fluid's specific gravity against that 1.9 ceiling before you commit: if your actual contents come in under 1.9 SG, you have margin to spare. Note that 1.9 SG is the heaviest-contents rating offered on this shell, so any fluid above 1.9 SG is out of scope for this tank entirely - not a "size up" path. For layout, the 48.0 x 48.0 footprint and 73-inch height are the two dimensions to plan around first, and the level gauge keeps you from guessing at inventory or risking an overfill.
Siting, fittings, and setup
A loaded 405-gallon tank concentrates real weight onto a small 4-foot-by-4-foot square, so the pad underneath matters. Walk through the concrete pad sizing guidance for above-ground polyethylene tanks before you set it, and if you are still deciding between capacities, the Tank Sizing Calculator and Tank Sizing Guide help you right-size against your throughput. This listing does not publish a fitting or outlet schedule, so before you order, confirm bulkhead fitting size, gasket material, and outlet placement against your plumbing - for used-oil service the gasket elastomer, not just the poly wall, is often the real compatibility limiter. If the level gauge spec matters to your operation, our overview of tank level gauge selection walks through how the different gauge technologies behave.
The mistake to avoid
The most common error on a containment tank like this is assuming the polyethylene resin alone qualifies it for any fluid. The 1.9 SG rating tells you the wall can bear the weight of dense contents, but it does not by itself certify chemical compatibility - always confirm your specific oil, additive package, or waste stream against the manufacturer's chemical-resistance data, concentration- and temperature-specific, before filling. Two more things to verify: this listing does not state a secondary-containment volume, so check whether your spill-containment requirement (often 110% of the largest vessel) is met by this unit or calls for an external berm or pad; and do not push fluids hotter or more aggressive than the resin tolerates.
