The “Silico-550 Double Ply” is a high temperature duct suited for a variety of applications involving hot air and fumes. This air ducting hose consists of double-ply silicone coated fiberglass reinforced with a spring steel wire helix & external filament fiberglass cord. This allows the high temperature duct to be suited for high-temp air handling applications that are ideal for plastic processing operations. The “Silico-550 Double Ply” is also a flexible air hose that has a narrow pitch for flexible venting. This allows the hose to offer a tight bending radius that is non-kinking while maintaining a smooth airflow. While the flexible air hose allows for flexible venting, it is not recommended for continuous flexing.
The “Silico-550 Double Ply” high temperature duct is designed for both high and low temperature extremes. The air hose can operate in temperature lows down to -65 degrees Fahrenheit and can withstand highs up to 550 degrees Fahrenheit (600 F intermittently). In addition, the air ducting hose is also resistant to many oils, solvents, ozone, water, fungus and alkalis. Please consult our Chemical Resistance Guide for specific resistivity of the hose with your media.
The “Silico-550 Double Ply” high temperature duct comes in a standard length of 12 feet and is iron oxide red in color. The air hose is available in a wide range of internal diameter sizes including 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10 and 12 inches. Standard hose ends are plain cut, but factory-sewn cuffs are available. The air ducting hose applications in various markets include aircraft, automotive, brake ducting, brick kilns, rocket support duct, tractor pull exhaust, transmission cooling and vehicle exhaust systems.
