Insulated Bend-and-Stay Metal Duct Hose for Air
- Very Flexible
- Compatible Clamps: Worm-Drive Clamps
- Color: Silver
- Temperature Range: -100° to 435° F
Bend this hose into position in heating and cooling applications where it’s important to maintain the temperature of the air inside the hose. Unlike fabric duct hose, this lightweight aluminum hose holds its shape once it’s curved around corners. It’s insulated with a layer of fiberglass, so it keeps air flowing through at a consistent temperature even when it’s routed through hot or cold spaces. The metalized film cover seals out moisture, protecting the insulation underneath.
This hose is not meant to be continuously flexed. Lengths beyond 6 ft. may need support.
