The Snyder Industries 2500 Gallon Cone Bottom Tank (SKU 5110000N49) is a black polyethylene cone-bottom tank built for full-drain chemical and process service where you need every gallon to evacuate without manual scraping or a sump. The tank body stands 125 inches tall on a 90 x 90 inch footprint, holds 2,500 gallons, and carries a 1.5 specific gravity rating, meaning the resin wall is engineered to safely hold contents up to 1.5 times the weight of water. That SG number is the single most important spec on this page, and it dictates which chemicals you can store. Size and site it with the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a stand or pad.
Specs, fittings, and weight loads
A cone-bottom tank cannot stand on its own; it requires a matching stand to elevate the discharge point. Note that the 125-inch dimension is the tank body alone, and the stand adds discharge height on top of that, so verify your door, ceiling, and fill-port clearance before ordering, and review the Cone Bottom Tank Stand Compatibility Matrix so the legs and saddle match the tank you order. Per the technical drawing on this page, the tank is fitted with a flange, an 18-inch PE threaded and vented opening, and a manway with 15-inch access for entry and cleaning. Every one of those penetrations is a potential leak point, so the gasket and fitting material at each opening has to match your chemical, not just the tank wall. Plan your load carefully: filled with water this tank weighs about 20,850 lb, and at its maximum 1.5 SG rated contents it reaches roughly 31,275 lb. Your stand, anchor points, and slab have to carry that fully loaded figure, not the dry weight.

Chemical compatibility
This tank is molded in polyethylene with a 1.5 specific gravity rating. The resin is recorded as HDLPE but is not yet confirmed, so confirm HDLPE versus XLPE with us before placing any chemical into service, because crosslinked and linear polyethylene behave differently with certain reagents. Within the 1.5 SG limit, this tank is rated for acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), and urea solution (50%); it is also rated for ozonated water up to 10 PPM, though we ask that you confirm oxidizer service and ozone PPM with us before sizing the fittings. Fitting and gasket selection matters as much as the tank wall. Most of these chemicals run PVC fittings with EPDM gaskets, acetic acid and urea solution call for PP/PVC fittings, and DEF is the trap on this tank: it breaks the default and requires 316SS fittings with an EPDM gasket, so do not reflexively spec PVC at the outlet for a DEF install. Always confirm against the OEM chemical-resistance chart for your exact concentration and operating temperature.
Some chemicals are denser than a 1.5 SG tank can safely hold and require the higher 1.9 SG version of this tank instead. The high-demand ones to watch for are sodium hypochlorite, sulfuric acid, hydrochloric acid, and ferric chloride, several of which also need Viton gaskets rather than EPDM. Ethylene glycol, hydrofluoric acid, hydrogen peroxide, phosphoric acid, potassium hydroxide, and roughly a dozen others fall in the same higher-SG category; if your application is on that list, talk to us about the 1.9 SG tank rather than forcing this one past its rating.

The mistake to avoid
The most common and costly error with a 1.5 SG cone-bottom tank is loading a denser chemical than the wall is rated for. Sodium hypochlorite and sulfuric acid, for example, look like routine water-treatment chemicals, but both need the higher 1.9 SG tank and aggressive-service Viton gaskets, not EPDM. The second mistake is overlooking the gaskets and fittings at the outlet and manway: matching DEF to 316SS or acetic service to PP/PVC is what keeps the penetrations from failing before the tank does. For containment-code planning around chemical storage, the Snyder Captor Plus 110% Containment vs UL-142 / SPCC comparison walks through the secondary-containment question.
