The Snyder Industries 275 Gallon Double Wall Tank (SKU 5740102N30) is a double wall tank molded in opaque white HDLPE (resin #880046) and rated to a 1.9 specific gravity. That high SG rating is the headline spec: the tank wall is engineered to hold contents far heavier than water, and the double-wall construction wraps the primary tank in an integral secondary containment shell. At 63 inches tall on a 47 x 47 inch footprint, this 275 gallon double wall tank fits a compact containment pad while still giving you real volume.
Will it work for your application
Start with weight, because that is what catches people off guard on a heavy-content Snyder tank. Filled with plain water it carries about 2,294 lb. At its maximum 1.9 SG rating the contents alone can reach roughly 4,358 lb, so size your pad, saddle, and anchoring to that loaded contents figure plus the tank's own dead weight, not to the water number. The 47 x 47 inch square footprint and 63 inch height give you the clearances to check against your space before it ships.
Size the working volume, not the nameplate
The 275 gallon rating is the tank's geometric capacity, not the volume you can safely fill. Freeboard for thermal expansion means your usable working volume is meaningfully less than 275 gallons on a heavy-density fill. Use the Tank Sizing Calculator and the Tank Sizing Guide to derive the number you can actually put to work, and see the freeboard sizing walkthrough per ASTM D1998 for how density and expansion cut into that figure.
The mistake to avoid
Do not spec fittings, gaskets, or a pump against the tank shell alone. Confirm the fitting configuration for this specific tank with us by phone before you order, and verify every wetted material against the manufacturer's concentration- and temperature-specific chemical-resistance chart. Confirm your contents stay within the 1.9 SG ceiling; if your chemistry is at or above that rating, call 866-418-1777 and we will confirm the right configuration for your service. Because this is a Snyder double wall tank built for secondary containment, it is often specified where containment is a requirement, not an option, our SPCC 40 CFR 112 compliance walkthrough shows where these fit in a spill-prevention plan, and the concrete pad sizing framework walks the loads.
