40‑Gallon Poly Oval Stock Tank (Model ST40)

The ST40 40‑Gallon Oval Stock Tank is a durable, multi‑purpose poly tank designed for livestock watering and a wide range of farm, ranch, and utility applications. Built tough for long‑lasting performance, this tank is constructed from heavy‑duty poly material with a molded‑in rim that provides added strength and makes handling easier during transport or cleaning.

Its oval shape helps eliminate corner stress, giving the tank improved structural integrity over time. The 40‑gallon capacity makes it an excellent choice for small to medium‑size livestock or multipurpose use around the property. These tanks are also commonly repurposed as hay tubs, storage bins, chick brooders, planters, cooling tubs, and more—offering true flexibility for any operation.

A drain plug with a standard ¾‑inch fitting (included on some versions) allows quick draining or easy hose attachment when used as a watering vessel.
