Product information
The Duct Hose is specially designed for air transfer and ducting applications in industries where temperature resistance, airflow stability, and structural durability are essential. Built with fibreglass fabric reinforcement and a 316L stainless steel helical wire, this hose maintains its shape under heat while offering controlled flexibility for semi-static installations.
Key features
- Air and gas transfer — optimised for ducting, ventilation, and controlled airflow lines
- Fibreglass reinforcement — provides high heat resistance and added strength
- SS 316L helical wire support — prevents collapse and ensures hose integrity under stress
- Semi-flexible design — allows minimal bending while maintaining airflow stability
- High temperature endurance — operates reliably from −60 °C to +260 °C
- Clean and compliant — platinum-cured silicone, FDA and USP Class VI approved
Why Choose Makvin?
This duct hose combines the thermal stability of fiberglass, the strength of stainless steel reinforcement, and the purity of platinum-cured silicone, making it a safe and reliable solution for controlled airflow in sensitive and high-heat environments.

Datasheets, material declarations (FDA / USP Class VI), RoHS/REACH statements and dimensional drawings for this product are issued on request with your quotation.
Request documentationPlatinum-cured silicone is addition-cured — odourless, low in extractables and preferred for medical, pharmaceutical and high-purity food contact. Peroxide-cured silicone is a robust, cost-effective choice for industrial and non-critical transfer. We supply both and will advise the right grade for your process.
Yes. Most items are produced to your drawing — bore/OD, wall, length, cross-section, durometer and colour. Send dimensions with your quote request.
Depending on the grade selected: FDA 21 CFR 177.2600, USP Class VI, ISO 10993, EU 1935/2004 food-contact, RoHS and REACH statements, plus batch material certificates and dimensional reports.
Sampling quantities are available for evaluation. Production MOQ depends on the profile/tool; we confirm it with the quotation.
Stocked lines ship within a few working days. Custom extrusions and moulded parts are typically confirmed per order after drawing sign-off.
