Elliptical-cross-section polyethylene tanks deliver the lowest center of gravity available in a horizontal vessel — engineered specifically for highway transport, pickup-bed mounting, and trailer-skid use. The ellipse shape (wider than tall) reduces roll moment and surge sloshing vs. a round horizontal of equal capacity, and packages cleanly into a standard 8-foot or 6.5-foot pickup bed. Catalog covers Norwesco, Snyder Industries, Chem-Tainer, Enduraplas, and Bushman elliptical and pickup-bed SKUs.
Applications
Pickup-bed water and chemical transport (300–1,000 gallon)
Trailer-mounted nurse-tank service for spray rigs
Mobile DEF / AdBlue and fuel transport (verify resin compatibility)
Wildfire response and emergency water transport (low CG critical for off-road)
Agricultural transfer between field and central fill point
Compliance & Standards
Typically rotomolded to ASTM D1998; FDA 21 CFR 177.1520 resin compliance varies by model (see each product's Specifications). Internal baffles are typical on elliptical transport tanks — baffles reduce surge by 60–80% and are required practice for any partial-fill transport. For non-hazmat ag/water transport, follow OEM strapping and load-securement specifications. Hazmat cargo transport invokes DOT 49 CFR Part 178 — consult your shipper.
Engineering & Selection
Three things to confirm before ordering: (1) bed footprint — most pickup-bed elliptical tanks list outside dimensions; measure your bed between wheel wells and tailgate. (2) Strapping points — molded-in strap channels or external lugs; verify you can secure to your bed rail or trailer deck. (3) Outlet position — typically end-mounted for gravity drain or pump suction; some include sump for total drain. Verify before ordering.
Freight & Delivery
Tanks ship LTL motor freight from the closest stocking warehouse to your delivery ZIP. Typical transit 5–10 business days. Liftgate available at delivery (per-shipment fee). Always inspect at delivery and note damage on the bill of lading before signing — that is the carrier claim trigger. Bulk-order consolidation reduces per-tank freight 25–40%.

Sizing & Selection
Match capacity to your bed or trailer payload rating (water = 8.34 lb/gal). Don't forget tank weight + securement + fluid + any pump/plumbing. 866-418-1777 for sizing review.
