80/80/80/80 Gallon Rhino Tuff Tanks Gravity Feed System No Valve (MPN: RTT-3333-NV)

Description

The 320 Gallon Stackable Fluid Storage System is a high-capacity, space-saving solution engineered for efficient fluid storage and dispensing across industrial, agricultural, fleet, and commercial applications. It includes four 80-gallon stackable tanks, a heavy-duty stand with 24″ legs, a drip tray kit, and a complete accessory package, making installation fast and hassle-free.

Crafted from natural virgin high-density polyethylene, each tank is designed to deliver exceptional chemical resistance and long-term durability in demanding environments. With interlocking ridges, molded-in 304 stainless steel drain fittings, and built-in site gauges, this system is ideal for safely managing oils, lubricants, DEF, and other compatible non-potable fluids.
