- Material: Polyethylene
- Color: Blue
Bend this hose around obstructions and corners, and the aluminum tube reinforcement holds its shape. Couple the hose with fittings (sold separately).
To attach fittings to the hose, make a clean cut with the cutting tool, then use the deburring tool to bevel the inside of the hose.
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.

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.
