Description

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.

Very useful

Black Double Layer Silicone Air Ducting

Out with the cardboard and foam and in with the Silicone

The order **** very quickly and I fitted them on my 1977 Citroen 2cv the next day. I thought I would try them as mine were requiring replacement and I saw an article in the 2CVGB magazine by someone who had just replaced his.
Easy to cut and fit once I had worked out the bends required and the air flow is much improved.
The only downside I find is that engine noise inside the car has increased as the old cardboard and internal foam ones absorbed some of the noise.

Great product at a great price

Great product, exactly as described I bought it to replace a tired old fabric duct fitted to my cold air intake system. This fitted on nicely with a jubilee clip and works really well

Excellent Ducting

When I first saw the heater pipe arrangement on a 2CV, I thought they looked a wee bit “hit & miss”, but I hadn’t appreciated that the cardboard tubes were lined with foam.
On the occasional use of our 2CV during the winter, there was not much heat coming onto the driver’s windscreen and yet, the heat exchangers and cable adjustments were all perfect. The foam within the driver’s side screen pipe had folded in on itself, not at the ends but halfway down the pipe. I tried to coax it back into position with a broom handle, but it kept bulging and blocked the flow of air.
I bought two meters of this silicon (double layered, coil wound) heater pipes . One length was 63mm diameter and the other 70mm diameter. The difference to the heater performance is astounding. They are available in red, blue, grey or black. If I were to order again I'd probably opt for grey, but the "red" versions guarantee an extra few horsepower, which (if you own a 2CV) is always welcome!
I have written an article for the 2CVGB Club magazine, recommending this product, so hopefully you'll pick up a few more orders.
Thank you!

Will Silicone Hose Stretch?

Silicone hoses are known for their flexibility and elasticity, which allows them to stretch to some extent. However, the degree to which a silicone hose can stretch depends on various factors, including its design, thickness, and the specific type of silicone used in its construction. We advise that our hoses can stretch a maximum of 3mm on the diameter.

Can Silicone Hoses Be Used For Coolant?

Yes, silicone hoses are commonly used for coolant applications. Silicone hoses are well-suited for coolant systems in various industries, including automotive, marine, and industrial applications.

How Long Do Silicone Hoses Last?

The lifespan of silicone hoses can vary depending on several factors, including the quality of the material, the specific formulation of the silicone, the environmental conditions, and the type of application. In general, silicone hoses are known for their durability and longevity, and they often outlast traditional rubber hoses in many applications.

What is the temperature rating of silicone hoses?

The temperature rating of silicone hoses is typically in the range of -60°C to +180°C (-76°F to 356°F). Silicone hoses are known for their ability to withstand a wide range of temperatures, making them suitable for various applications in industries such as automotive, aerospace, and manufacturing. It's important to note that specific products may have slightly different temperature ratings, so it's advisable to refer to the manufacturer's specifications for precise details on a particular silicone hose.
