Bend-and-Stay Metal Duct Hose for Fumes

Bend into position and this hose holds its shape without springing back or requiring support, so it can bend around equipment, piping, and other obstructions. Use it to vent smoke, sparks, paint fumes, welding fumes, and oil fumes. It's not designed for continuous flexing—larger diameters of 8" and above require more force to bend.

A raw, cut end leaves the spiral and hose material exposed for connecting with a fitting or cuff.

Aluminum—One-third the weight of steel, aluminum is commonly used in applications with weight limitations. It resists rust as well as stainless steel, but it's not as strong.
