Details

The Webasto PAPK Air Hose (Article Number: 79227405) is a professional-grade, flexible hot air ducting solution specifically designed for air distribution in diesel-fired heating systems, such as the Webasto Air Top series and Eberspacher Airtronic units. This hose features a 90 mm (3.5 inch) internal diameter and is supplied in a 5-meter (16.4 ft) length, making it ideal for marine, RV, campervan, and commercial vehicle installations where long, continuous runs or complex routing are required. The hose is constructed using high-quality APK material, which stands for Aluminum (inner layer for heat reflection), Paper/Cardboard (center layer for flexibility), and Kunststoff/Plastic (outer layer for protection against moisture and abrasion). This multi-layered design ensures the hose is heat-resistant for continuous warm air flow while remaining lightweight and easy to shape by hand. It can be routed through tight engine compartments or chassis spaces and maintains a minimum bending radius of approximately 270 mm. This component is essential for maintaining an efficient and safe heating system, ensuring that warm air is effectively transported from the heater unit to various outlets throughout the vehicle or vessel.
