Double Layer Silicone Air Ducting is a high-temperature flexible hose designed for air transfer in automotive, motorsport, marine, and industrial applications. Manufactured from two layers of silicone-coated glass fibre with a steel wire helix reinforcement, the ducting offers outstanding heat resistance, flexibility, and durability. Its double-layer construction provides greater strength and insulation compared to single-layer alternatives, while the smooth inner surface ensures efficient airflow with minimal pressure loss. Lightweight yet robust, this ducting is ideal for hot air transfer, induction systems, and engine bay ventilation where reliability under extreme heat is essential.

Key Features:

• Material: Double-layer silicone-coated glass fibre for superior heat resistance.

• Reinforcement: Steel wire helix for flexibility and crush resistance.

• Construction: Twin-ply wall with smooth inner bore for efficient airflow.

• Operating Temperature: Continuous service from -70°C to +260°C, with peaks up to +280°C.

• Flexibility: Highly flexible for routing in tight engine bays and confined areas.

• Applications: Hot air ducting, induction systems, cooling ducts, and engine bay ventilation.

The double-layer silicone-coated construction ensures outstanding resistance to heat, ozone, and ageing, while the embedded steel wire helix provides flexibility without risk of collapse under suction or tight bends. Its smooth inner bore reduces turbulence and pressure loss, ensuring efficient airflow in high-performance applications. Strong yet lightweight, the ducting is easy to handle, cut, and install, making it suitable for both professional workshops and custom-builds.

Applications include automotive induction and cooling systems, brake cooling ducts, turbocharger air feeds, HVAC ducting, marine engine ventilation, and industrial hot air transfer. Double Layer Silicone Air Ducting is widely used in motorsport, custom fabrication, and engineering projects where high heat resistance, flexibility, and durability are required.
