Bend-and-Stay Metal Duct Hose for Air

Very Flexible
Compatible Clamps: Worm-Drive Clamps
Temperature Range: -100° to 435° F

Unlike fabric duct hose, this lightweight aluminum hose can bend around corners and hold its shape. Hose is not for continuous flexing. The hose may need support.

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.

Bend-and-Stay Very Flexible Duct Hose for Dust

Very Flexible
Compatible Clamps: Worm-Drive Clamps
Color: Brown or White
Temperature Range: -4° to 175° F

Bend this hose in any direction and it will hold its shape without support. Create longer lengths by twisting one end of the hose into another—no need for a duct hose connector or clamp.

Warning: Hose should not be used for applications that generate a static charge.

Bend-and-Stay Very Flexible Metal Duct Hose for Fumes

Very Flexible
Compatible Clamps: Worm-Drive and Twin-Ring Clamps
Temperature Range: Aluminum: -100° to 400° F; 304 Stainless Steel: -400° to 800° F

Form elbows and bends with this hose and it will hold its shape without support. Hose is not for continuous flexing. Use with smoke, sparks, paint fumes, welding fumes, and oil fumes. For IDs 8” and larger, expect a bit more rigidity due to its large diameter. It’s still bendable but will require more force than smaller sizes to shape.

Aluminum is lighter than stainless steel and has good corrosion resistance.

304 stainless steel is more durable than aluminum and has very good corrosion resistance.
