This tank is manufactured for you when the order is placed. Returns are not accepted on special order products like this one. Elkhart Plastic tanks are manufactured to meet quality and health safety standards. With fewer impurities, these tanks are strong enough to take the bumps and bangs without compromising the security of your fresh water storage. Elkhart Plastics uses a process called roto-molding in which high-density plastic is rotated and molded into shape. This process creates a seamless tank in which the walls are of equal thickness, with no weak spots to cause trouble later. It is this process that has earned Elkhart Plastics the reputation for quality tanks. The dimensions of this tank are 44" in length, 28" in width and 7 1/2" in height with a wall thickness of 0.180”.

Seamless One-Piece Construction: Engineered without seams or joints for superior strength and leak-proof reliability, outlasting and outperforming typical OEM tanks.

Stain, Corrosion, and Rust Resistant: Designed to stay clean and functional even after years of use, ensuring your water stays fresh and your tank stays dependable.
