The Little Giant Fill-Fast Giant Funnel is perfect for heavy-duty liquid applications like fueling equipment and mixing chemicals. Designed to withstand rugged farm, ranch, agricultural, automotive and industrial use. Heavy-gauge, corrosion-proof polyethylene plastic can be used with practically any chemical and never corrode or rust. Initially designed for use in cold climates, these funnels hold up under tough environmental conditions. Ribbed construction allows air flow for easy pouring. Comes with a built-in hang tab and rust-proof fine mesh brass filter screen that is heat sealed in place for long wear (keeps the bugs out of your fuel tank).
