The Snyder Industries 3600 Gallon Black XLPE Heavy Duty Cone Bottom Tank (SKU 8050000N48) is a crosslinked polyethylene cone bottom tank built for full-drain chemical service at a 1.9 specific gravity rating - the top of Snyder's chemical-duty range, with no heavier-rated XLPE step above it for these chemistries. It holds 3,600 gallons, stands 125 inches tall on a 102 x 102 inch footprint, and the cone-bottom geometry empties completely so you are not left fighting settled product or a residual heel. The black XLPE wall blocks UV better than standard HDPE, which is why operators searching for a Snyder cone bottom tank in black XLPE land here for aggressive storage rather than a water-grade vessel.
Will it work for your application?
This is crosslinked linear polyethylene (XLPE), not HDPE. The 1.9 specific gravity rating means the resin and wall thickness are engineered for liquids up to 1.9 times the density of water, so dense brines, sulfates, and chloride solutions sit within the tank's design envelope. Confirm your liquid's actual specific gravity against that 1.9 number before you order - that single check is the most common cone-bottom mistake. If you are sizing this against your draw rate and headroom, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. For the deeper question of when crosslinking actually earns its place over HDPE, see Snyder XLPE vs HDPE: When Crosslinking Matters for Chemistry Duty.
Weights, support, and the support stand
Plan your pad and any stand around real loaded weight, not the empty shell. Filled with water this tank carries 30,024 lb; loaded to its maximum rated contents at 1.9 SG it reaches 57,046 lb. A cone bottom tank cannot sit on flat ground - the cone must be fully supported in a matching steel stand, and you size the stand and the slab for that 57,046 lb worst case plus the contents you actually run. Dimensions and fitting locations are on the technical drawing on this page; note that the published spec here pairs fitting and gasket materials but not outlet sizes or bulkhead locations, so confirm your outlet size and fitting layout against the drawing or by phone before you buy fittings. For matching a stand to this Snyder cone, use our Cone Bottom Tank Stand Compatibility Matrix, and for monitoring level on dense or foaming chemistry see Tank Level Gauge Selection for Chemical Service.
Chemical compatibility
This tank is black XLPE rated to 1.9 specific gravity. The chemicals below are compatible with the XLPE wall at the listed concentration, with the fitting and gasket materials the chemical-resistance chart pairs with each one. Most rows take PVC fittings and EPDM gaskets, but watch the exceptions: Hydrofluosilicic Acid requires Viton gaskets rather than EPDM, and DEF requires 316SS fittings. A few rows also hold at extreme strength - Ethylene Glycol is rated at 100% (neat glycol) and Potassium Hydroxide at saturated - per the chart. Compatibility is always concentration- and temperature-specific, so verify your exact conditions against the manufacturer's chemical-resistance chart and our Chemical Compatibility Database before committing a tank to service.

This tank ships LTL freight from the Snyder plant in Marked Tree, AR, with the cost quoted live to your ZIP - get a number in seconds with the Freight Cost Estimator or call 866-418-1777. If you are running DEF or another row that calls for 316SS or PP fittings rather than PVC, call to confirm sizing before you order. Match the right fittings and gasket material to your chemistry using our Chemical Compatibility Database, confirm the support stand before delivery, and if you have a chemical not listed here, call 866-418-1777 and we will work it through with you.
