Product Description

The Flexaust Heat-Flex GS fiberglass duct hose, used for high temperature ventilation and fume exhaust applications, is an iron-oxide red, silicone-coated, double-ply fiberglass fabric hose, reinforced with a spring steel wire helix and external filament fiberglass cord. It resists water, fungus, ozone, alkalis, and a wide range of oils and solvents, and is very flexible and highly compressible for easy installation. A temperature range of -65 to 550 degrees F makes it suitable for applications such as garage exhaust, rocket support, transmission cooling, and hot air drying systems. This non-kinking fiberglass duct hose has a narrow-pitch helix to allow a short bend radius while maintaining efficient flow.

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 “spiral.” 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.
