The Snyder Industries 275 Gallon 15 Degree Plastic Cone Bottom Tank is a closed-top, full-drain vessel molded from white polyethylene and rated to 1.9 specific gravity. The 15-degree cone bottom self-drains low-viscosity product through the apex, so you finish batches clean without manual sumping. At 63 inches tall on a 42 x 42 inch footprint, this cone bottom tank fits a standard cone-bottom stand and tucks into tight chemical-feed rooms while still giving you 275 gallons of working volume.
Will it work for your application
Full of water this tank carries 2,294 lb, and at its 1.9 specific gravity rating it is engineered for contents up to 4,358 lb - use that max-rated weight, not the water figure, when you size the stand and slab for a dense chemical. The 1.9 SG rating is the spec that governs how dense a liquid this tank can safely hold within its design margin; 1.9 is also this tank's maximum density rating, so for product heavier than roughly 15.8 lb/gal you should confirm a steel or FRP vessel, since polyethylene cone bottoms top out here. Cross-check your filled weight against the Tank Sizing Calculator or the Tank Sizing Guide, and if you are choosing between cone angles or stand styles, the cone bottom tank buyer's guide on 15 vs 30 vs 45 degree selection and the cone bottom tank stand compatibility matrix walk through the trade-offs.
Chemical compatibility
This is a 1.9 SG polyethylene cone bottom; the resin is recorded as HDLPE, but we will confirm the exact resin (HDLPE vs. XLPE) for your chemical and concentration before you order - call 866-418-1777 - because the two crosslink differently and that distinction governs long-term chemical resistance. Always verify against the OEM chemical-resistance chart for your exact concentration and operating temperature, since compatibility is concentration- and temperature-specific and the right fitting and gasket material matters as much as the tank wall. Within this tank's rating, the following are compatible, with the fitting and gasket materials that pair with each:
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
Notice how the wetted materials shift with the chemical. The strong and oxidizing acids in this list - hydrochloric, phosphoric, sulfuric, hydrogen peroxide, sodium hypochlorite, plus the HF-family acids hydrofluoric and hydrofluosilicic - pair with Viton rather than EPDM, and peracetic acid steps up to Aflas. DEF and peracetic acid call for 316 stainless fittings. Do not default to plain PVC everywhere: 98% sulfuric acid needs CPVC, while propylene glycol and zinc orthophosphate run on PP/316SS. Matching the wetted materials to your chemical is the most common mistake on a cone bottom install - get it right by working from the Chemical Compatibility Database for your specific service.
Fitting placement and freight
This tank's fitting package is not specified in the listing, so confirm standard versus custom outlet and fitting configuration by phone before ordering. On a closed-top cone bottom, where you put the vent, fill, level, and drain connections determines whether the tank drains cleanly and stays operator-safe; our tank top fitting placement strategy guide covers vent, fill, level, drain, and vapor-recovery layout. If you are weighing this open-feed cone bottom against a bunded option, the Snyder Captor Plus 110% containment vs UL-142 comparison spells out when secondary containment is required. Confirm the connection layout against the technical drawing on this page before ordering.
