The Flexaust Flexadux T-7SR thermoplastic rubber duct hose, used for ventilation, dust removal, fume extraction, and bulk material handling applications, is a black, thermoplastic, rubber-coated, reinforced, non-woven polyester fabric hose, reinforced with a spring steel wire helix; it resists chemicals, ozone, ultraviolet (UV) light, moisture, abrasion, tears, and punctures, and is flexible and compressible for easy manipulation. A temperature range of €“50 to 285 degrees F makes it suitable for applications such as fume extraction and industrial ventilation. This thermoplastic rubber-coated polyester duct hose has a wall thickness of 0.024 inch, and is more resistant to tears, punctures, and abrasion than woven neoprene and standard thermoplastic rubber hoses. It is available with factory-installed 2-inch soft cuffs.

Duct hoses are flexible or rigid tubes that convey gases, liquids, and lightweight bulk materials from one location to another. They are made from an array of materials that range from polyurethane and thermoplastic rubber, to PVC and aluminum-coated fiberglass fabric, and are typically reinforced with a steel wire or rigid plastic helix, also known as a €œspiral.€ Duct hoses are secured with hose clamps or U-bolts, and two pieces of hose are joined with a hose connector. Common applications for duct hoses include heating and cooling, ventilation, fume and smoke exhaust, vacuum cleaning, moving chips and shavings, handling bulk packing materials, and water and waste discharge.

Flexaust manufactures flexible hose, metal ducting, and accessories for industrial and commercial applications. The company, founded in 1938 and headquartered in San Diego, CA, is part of the international Schauenburg Group.
