Key Advantages
This corrugated heat protection tube outer layer is aluminum, which can reflect at least 90% radiant heat. The inner layer of fiberglass prevents contact of the metal with other components, providing protection even at high temperatures. It is ideal for control cables, gear cables, cooling tubes, and heat-sensitive parts in the automotive sector.
⚠️
Application Notice: The combustion air hose should be installed away from direct exhaust heat and securely clamped to ensure safe and efficient heater operation.
Frequently Asked Questions
What materials are used in this combustion air hose?
The hose features a dual-layer construction with a spiral-reinforced aluminum inner core and a black PVC outer layer for moisture and abrasion resistance.
Is this hose compatible with Webasto diesel heaters?
Yes, it is fully compatible with Webasto, Eberspacher, and most Chinese diesel parking heater systems.
What is the temperature range for this product?
The hose is designed to withstand thermal conditions from -40°C up to +350°C, making it ideal for heater intake applications.
Can the length and diameter be customized?
Yes, we support customization for both diameter (range Ø8mm - Ø140mm) and specific lengths upon request.
What is the bending radius of the hose?
The bending radius is approximately 1.5 times the internal diameter (ID), allowing for easy routing in confined vehicle spaces.
Does the outer layer reflect heat?
The aluminum outer layer is highly reflective, capable of reflecting at least 90% of radiant heat to protect internal airflow and nearby components.
