Dee Zee's square transfer tank is perfect for transporting water or other non-flammable fluids. You'll find it invaluable the next time you need to mix concrete or wash tools at a site without water access. Constructed of heavy 14 ga steel with radius curves to eliminate weld pressure points. The smaller size of the square transfer tank maximizes truck bed space while transporting up to 53 ga of fluid. Joins securely to your truck bed with rugged mounting tabs. Our transfer tanks are protected by white NRT rust inhibitor powder coat finish to help protect the box and keep it looking great for years. Tanks feature lockable cap to keep fluid safe and secure plus a 0.375 in drainage plug and venting coupler for easy drainage when needed.
