About Duct Hose

Very Flexible
Compatible Clamps: Worm-Drive and Quick-Release Clamps
Color: Orange
Temperature Range: -65° to 550° F

If you’re tight on storage space, this hose compresses down to a small size. It is for use with smoke, water-based paint fumes, welding fumes, and oil fumes.

High-Temperature Flexible Duct Hose for Fumes

Flexible
Compatible Clamps: Worm-Drive Clamps
Color: Black or Red
Temperature Range: Neoprene Coated: -65° to 300° F; Silicone Coated: -75° to 500° F

Combining the heat resistance of metal with the flexibility of fabric, this fiberglass hose has a special coating that stands up to high temperatures. Hose is for use with smoke, water-based paint fumes, and welding fumes.

Silicone-coated hose handles a wider temperature range than neoprene-coated hose.

Hose with cuffed ends has finished edges for easy attachment to duct hose connectors.

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