These fiberglass duct hoses have been coated with PVC (polyvinyl chloride). They are used to blow or exhaust low volumes of cool and warm air in general fume-removal and welding fume-removal applications in the metal-processing and shipyard industries. They are also well suited for ventilating photo-reproduction machines and fine-dust collection systems. These flexible hoses are flame-retardant and self-extinguishing. They also resist damage from exposure to UV rays and ozone.

These thermoplastic rubber duct hoses are reinforced with a wire helix that provides strength and durability, preventing collapsing or kinking under pressure or vacuum. They are used for fume-removal and dust-collection applications in the facility-service and municipal industries. These hoses provide excellent crush resistance and resist abrasion, chemicals, moisture, ozone, and UV rays.

These reinforced neoprene duct hoses have insulation for the temporary transfer of heated or cooled air for climate conditioning. They have a wire helix that provides strength and durability, preventing collapsing or kinking under pressure or vacuum. Neoprene is flexible and resists heat and flames.
