Our plastic elliptical tanks can be selected for stationary or transportable applications both indoors and outdoors. The elliptical tank lowers the center gravity to enhance stability and visibility. These tanks require the bottom to be fully supported with the cradle for use. These plastic tanks are manufactured from medium-density polyethylene with U.V. inhibitors. All tanks are equipped with gallon indicators and drain fittings. We offer all the cradles for the elliptical tanks.
