Neoprene-coated fiberglass duct hoses are used to blow or exhaust hot air for pellet drying applications in the plastics-processing industry. These lightweight, flexible hoses are flame-retardant and self-extinguishing. They can handle fumes at low pressures and moderately high temperatures, but they are not recommended for applications with continuous flexing, liquids, or abrasives.

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.

Silicone-coated fiberglass duct hoses are used to blow or exhaust hot air for pellet drying applications in the plastics-processing industry and to vent lavatory waste fumes and prelaunch fuel fumes in the aerospace industry. These lightweight, flexible hoses are ideal for high-temperature air flow and fume removal, and they can also be used for handling dust, fumes, and light powder. The hoses resist damage from exposure to UV rays and weather and will not kink. They have a smooth interior that maximizes air flow through the hose and minimizes friction. These hoses are not recommended for use with liquids or abrasive materials.
