The Snyder Industries 275 Gallon Double Wall Waste Oil Tank is a vertical HDLPE rotomolded tank built for used-oil collection and other heavier-than-water service. It carries a 1.9 specific gravity rating, which is what lets it hold dense fluids over its rated life. The yellow tank stands 63 in tall on a 47 x 47 in footprint, so it tucks into a shop bay or fluid-handling room without sprawling across the floor, and the integral double wall gives you built-in secondary containment instead of a separate poly basin. It is part of the Snyder double-wall line that ships from Arkansas and Mississippi facilities.
Will it work for your fluid?
Empty water-test weight runs about 2,294 lb, and at the full 1.9 SG rating the tank and contents reach roughly 4,358 lb, so plan your floor loading and equipment pad around that number. The double-wall design means the inner tank is wrapped by an outer shell that captures a leak before it reaches your floor, which is the whole point for waste oil and regulated fluids. As shipped it comes with a 2 in PE bulkhead fitting (BJO #TF220PE), an 18 in hinged polypropylene lockable manway, and an 18 in strainer-basket manway (#T8159000) so you can pour or pump in through a coarse screen that catches rags and debris before they hit the tank. Confirm the exact fitting layout and clearances against the technical drawing on this page before you set anchors or plumb the inlet.
Chemical compatibility
This is an HDLPE tank rated to 1.9 specific gravity, which makes it a candidate for a wide range of dense and aggressive fluids beyond waste oil; that 1.9 rating is the density ceiling for this listing, so call 866-418-1777 before specifying it for anything heavier. Always size your chemistry against the OEM chemical-resistance chart, which is concentration- and temperature-specific - the right tank can still be the wrong choice if your fitting and gasket materials don't match the service. As a rule of thumb from the chart below, most salts, glycols, and bases run on EPDM gaskets; strong acids and oxidizers call for Viton; and peracetic acid needs Aflas. Confirmed-compatible chemicals at the listed concentrations include Acetic Acid (60%, PP/PVC fittings, EPDM gaskets), Sulfuric Acid (98%, CPVC fittings, Viton gaskets), Hydrochloric Acid (37%, PVC, Viton), Phosphoric Acid (85%, PVC, Viton), Hydrogen Peroxide (50%, PVC, Viton), Sodium Hypochlorite (under 16.5%, PVC, Viton), Ferric Chloride (50%, PVC, EPDM), Aluminum Sulfate (50%, PVC, EPDM), Ethylene Glycol (100%, PVC, EPDM), Peracetic Acid (30%, 316SS, Aflas), and Potassium Hydroxide (saturated, PVC, EPDM), among others on our full chemical compatibility charts. The tank also handles DEF (32.5%) and urea solution (50%) on 316SS fittings with EPDM gaskets - a common fleet and fluid-handling use. Note that the as-shipped 2 in PE bulkhead and PP manway are not Viton, CPVC, or 316SS, so for sulfuric acid, DEF, or peracetic acid you will need to spec the wetted fittings and gaskets in those materials rather than assuming the stock hardware covers the service. Match the fitting and gasket material to your chemical, not just the tank wall.
Compliance and sizing the freeboard
For waste oil and other regulated liquids, the double-wall construction supports secondary-containment programs - see our walkthroughs on Snyder Captor double-wall tanks for SPCC 40 CFR 112 and RCRA 40 CFR 264.193 secondary containment for how the requirements apply, plus the Captor 110% containment vs UL-142 comparison. Before you fix a working volume, read our freeboard sizing per ASTM D1998 guide, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the 275-gallon size fits your throughput.
This double-wall vertical tank ships LTL freight from the Snyder plant in Marked Tree, AR, with the cost quoted live to your ZIP - run your address through the Freight Cost Estimator or call 866-418-1777 for a quote and to confirm fittings before you order. The most common mistake on a 1.9-SG tank is matching only the tank wall to your fluid and overlooking the fittings and gaskets - verify the 2 in bulkhead fitting and manway hardware against your chemistry first.
