Polypropylene duct hoses for air are primarily used on heaters, defrosters, air conditioners, and ventilation equipment in the marine and transportation industries. They meet Federal Motor Vehicle Safety Standard Number 302 (FMVSS 302), which specifies the burn-resistance requirements for materials used inside motor vehicles. These hoses are lightweight, flexible, and crush-resistant. They also resist damage from exposure to chemicals and moisture, are self-extinguishing, and provide good flex-fatigue resistance. The hoses are highly compressible, which saves space when transporting them.

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.

Reinforced PVC (polyvinyl chloride) duct hoses are used for moving large volumes of air in chemical fume-removal, general fume-removal, and solvent-ventilation applications in the food-manufacturing, chemical-manufacturing, pharmaceutical, industrial woodworking, and plastics-processing industries. These hoses can also be used for low-vacuum applications on dust-cleaning equipment. These hoses resist damage from chemicals and moisture, and they are made from transparent material that lets users see what's in the tube. The hoses are highly compressible, which saves space when transporting them.

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.
