The “Aluminum Flex 400” hi-temp hoses are great for funneling above ambient industrial air and fume. The metallic silver lightweight hose is constructed from a single-ply, helically corrugated aluminum alloy. The walls of the flexible ducts are constructed using a durable four-ply finished seam that has been folded flat and crimped for binding and strength. With a working temperature range of -100 to + 400 degrees Fahrenheit, these aluminum ducts are built to withstand extreme temperature applications. They are made to resist fatigue, weathering, and most corrosive fumes and chemicals. Aluminum flexible ducts are far more durable than their elastomeric counterparts, even when corrosive fumes are present.
This flexible ductwork is lightweight, pliable and can easily be bent or manipulated by hand. Our aluminum lightweight ducting is self-supporting, which means the hose will maintain its shape when bent. This important attribute helps in the formation of elbows for easy bending and turning during the installation process. This same self-supporting construction allows any bends to remain in place without the use of additional support materials. One thing to keep in mind is that flexible ductwork should not be exposed to repeated bending and moving. Flexible ducts are not recommended for continuous flexing. Hose connectors are also available for the “Aluminum Flex 400” flexible ducts. Use hose connectors (straight unions) to fit additional pieces of hoses together for extra length.
“Aluminum Flex 400” flexible ducts can be purchased in either 5 or 10 ft lengths. The flexible ductwork is available in several internal diameter sizes including 2, 3, 4, 5, 6, 7, 8, 9, 10, and 12 inches with internal diameter tolerances of -0.00 to +0.250 inch. These lightweight ducting can be utilized in a variety of applications that includes removal of the following: chemical fumes, circuit board cooling, exhaust systems, HVAC, oil mist removal, pollution control and ventilation. If you have any questions or need further assistance with these hi-temp hoses, please do not hesitate to contact one of our ducting experts today.
