Crush-Resistant Flexible Duct Hose for Exhaust Fumes
- Flexible
- Color: Black
- Temperature Range: -40° to 400° F
Commonly used in garages, this thick rubber hose will bounce back when stepped on or driven over. Use to vent carbon monoxide exhaust fumes while engine idling. Hose is also for use with smoke and water-based paint fumes.
2" to 4" ID hose has one end that is slightly larger than the other end. To make longer lengths, screw the smaller end of one hose into the larger end of another hose of the same size. When your application requires frequent movement or pulling, use a straight connector.
5" and 6" ID hose has two ends that are the same size. To make longer lengths, screw the ends of the hose into a straight connector.
