FAQ
Silicone Fabric Duct Hose — FAQ
What temperature can silicone fabric duct hose withstand?
Our silicone-coated fiberglass duct hose is rated for continuous operation from -30°C to +300°C (-22°F to +572°F). The fiberglass reinforcement with stainless steel helix maintains structural integrity even at peak temperatures, making it suitable for engine exhaust, industrial ovens, and high-temperature process ventilation.
Is silicone duct hose suitable for laboratory ventilation and exhaust?
Yes. Silicone fabric duct hose is widely used in laboratory ventilation, testing facility exhaust, and cleanroom applications. The silicone coating resists chemicals, solvents, and fumes commonly found in lab environments. Its self-extinguishing property meets fire safety requirements for laboratory installations. We supply to testing and inspection companies, pharmaceutical labs, and research facilities across the US.
What is the difference between silicone duct hose and PVC duct hose?
Silicone duct hose handles temperatures up to +300°C while PVC maxes out at +70°C. Silicone is also chemical-resistant and self-extinguishing, whereas PVC can release toxic fumes when overheated. For any application involving heat, chemicals, or flame risk — such as welding, engine exhaust, or laboratory ventilation — silicone is the correct choice. PVC is more cost-effective for ambient-temperature general ventilation.
Can I order custom lengths of silicone duct hose?
Yes. Standard length is 13 ft (4m) per section, but we manufacture custom lengths from 4 ft to 50 ft on our own production lines. Custom diameters from 2" to 16" are also available. We carry stock in our 5,000 m² warehouse in Brookshire, TX (Greater Houston area) for fast shipping. Contact us with your specifications.
What industries use silicone fabric duct hose?
Common applications include: automotive workshops (engine exhaust extraction), welding shops (fume capture), industrial ovens and kilns, laboratory and testing facilities (chemical exhaust ventilation), pharmaceutical cleanrooms, food processing (high-temp conveying), aerospace manufacturing, and petrochemical inspection facilities. Any environment with heat, chemicals, or flame risk benefits from silicone duct hose.
