The Enduraplas 55 Gallon DEF Tank (SKU REU055C09S) is a compact polyethylene fluid-transfer vessel built for diesel exhaust fluid and similar liquids. It holds 55 gallons in a Natural White body, stands 29 inches tall on a 27-by-31-inch footprint, and weighs 84 pounds empty, so one or two people can stage it without a forklift. An 8-inch lid gives you working access for filling and equipment, and the tank carries a 1.9 specific-gravity rating that speaks directly to how much fluid weight the wall is engineered to carry.
Will it work for your DEF or transfer fill?
DEF is a urea-and-water solution that runs around 1.09 specific gravity, and this tank is rated all the way to 1.9 — so its wall carries a large margin beyond what DEF actually demands. That headroom is the point: the same shell that stores DEF comfortably will also handle denser fluids if you repurpose it later. Filled with plain water the load is about 459 pounds, and the tank is rated to carry contents up to 872 pounds. Confirm your operating temperature stays within the 130°F / 54°C ceiling and that your fluid's specific gravity sits at or below 1.9 before you fill. Sizing a fleet or shop refill setup? The Tank Sizing Calculator and Tank Sizing Guide help you match this 55 gallon tank to your draw rate and refill cycle. See the technical drawing on this page for the full dimensional layout and lid placement.
Freight
This 55-gallon tank ships LTL from Texas, and freight is quoted live to your ZIP rather than folded into the list price. Run your delivery address through the Freight Cost Estimator to see freight before you buy, or call 866-418-1777 and we will quote it by phone. At 84 pounds empty it palletizes cleanly and moves as a light LTL shipment.
The mistake to avoid
DEF is chemically fussy about what it touches. This unit is lid-access at 8 inches with outlet and fittings configured to your order, so before you plumb it, confirm every wetted part — gaskets, valves, and fittings — is rated DEF-compatible and verify the material with the manufacturer for your service. Just as important, do not run the tank past its 130°F ceiling or fill it with a fluid heavier than its 1.9 rating allows. Check your fluid's specific gravity and service temperature against those two numbers before the first fill.
