The Snyder Industries 80 Gallon XLPE Square Dual Containment Tank is a double-wall containment unit built for secondary containment service, where a primary vessel and its catch basin need to occupy one compact footprint. It carries 80 gallons in a cross-linked polyethylene (XLPE) tank rated to a 1.9 specific gravity, stands 43 inches tall on a 24 x 24 inch square base, and is molded in white. The square geometry keeps the footprint tight against a wall or inside a bermed area, and the integrated outer wall serves as the containment basin, so you do not have to build and maintain a separate dike around a single-wall tank.
Will it work for your application
This is a double-wall containment tank, not a single-wall storage tank, so size it around the primary volume you intend to hold plus the freeboard the outer wall needs to capture a full release. Full of water, the tank carries about 667 pounds; at its maximum rated contents weight it reaches 1,268 pounds, which reflects the 1.9 specific gravity rating. The pad or structure underneath must carry that 1,268 pounds over the 24 x 24 inch base (576 square inches), so plan your foundation and anchoring accordingly and confirm your stored liquid's density falls at or below 1.9 before you commit. The 24 x 24 inch footprint and 43-inch height let it fit in mechanical rooms, on skids, and in tight chemical-feed corners. For help matching volume to your duty, run the Tank Sizing Calculator or read the Tank Sizing Guide, and for the foundation work see our framework on concrete pad sizing for above-ground polyethylene tanks.
Fittings and the compatibility you have to verify
Fitting and penetration sizes are not specified in this listing, so confirm the inlet, outlet, vent, and fill-port configuration with us at 866-418-1777 before ordering, and refer to the technical drawing on this page for fitting locations and exact contours. That gap matters because chemical compatibility on a double-wall tank has to pass on three separate materials, not just the resin. Before placing any product into service, verify your stored chemistry against the OEM chemical-resistance chart, at your actual concentration and temperature, for (a) the XLPE resin, (b) every gasket and O-ring, and (c) every fitting material you add. The 1.9 SG rating is the high-density tier for this style of tank, but it is a structural number, not a chemical one: it tells you the tank can hold a liquid up to 1.9 times the weight of water, not that the liquid is compatible with the materials touching it.
Why XLPE and the 1.9 SG rating matter
Cross-linked polyethylene is a denser, more impact- and stress-crack-resistant resin than standard polyethylene, which is why Snyder builds this containment tank in XLPE and rates it to a higher 1.9 specific gravity. If you are putting this tank into double-wall regulatory duty, our walkthrough on Snyder Captor double-wall tanks for SPCC 40 CFR 112 compliance and our guide to Captor freeboard sizing per ASTM D1998 cover freeboard, thermal expansion, and the usable volume you actually get inside a containment tank. People searching this tank by terms like containment tank, double wall tank, and XLPE land here for exactly that combination of secondary containment and a higher specific-gravity resin.
Freight and ordering
This containment tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, with the cost quoted live to your ZIP code rather than rolled into the listed price. Get a number before you order with our Freight Cost Estimator, or call 866-418-1777 and we will quote the lane and confirm lead time. Tell us your delivery ZIP, whether you need a liftgate or a residential delivery, and the liquid you plan to store, and we will confirm the fitting configuration and verify this XLPE double-wall tank is rated for the job before it leaves Arkansas.
