Diesel Heater Air Duct Hose
Diesel heater air duct hose with aluminum foil, kraft paper, glass fiber and PVC options. Corrugated flexible hot and cold air ducting for parking heaters, defroster ducts, air intake preheaters and generator ventilation. Sizes 6-140 mm (42/60/75/90 mm common). MOQ 50 m per size. OEM sizes, colors, lengths and packing available.
Diesel Heater Air Duct Hose — Product Overview
Our diesel heater air duct hose is a corrugated, flexible ducting solution built for hot and cold air transfer in vehicles, parking heaters and industrial equipment. The hose is produced from multi-layer material options — aluminum foil, kraft paper, glass fiber fabric and black PVC — so you can match the construction to your temperature, budget and appearance requirements. Standard inner diameters cover 6–140 mm, including the common 42 mm, 60 mm, 75 mm and 90 mm sizes used on diesel parking heaters. Every size can be cut to length by the metre, and the corrugated wall bends by hand in tight installation spaces without collapsing the airflow path. MOQ starts at 50 m per size, with OEM sizes, colors, labels and packaging available for your diesel heater air duct hose program.

Application Scenarios
- Diesel parking heaters and truck cab heaters — the diesel heater air duct hose carries warm air from the heater outlet into the cab or cabin; 42 mm and 60 mm are the most requested sizes.
- Automotive HVAC and defroster ducting — routes warm air to windscreen defroster vents and passenger footwells in cars, vans and buses.
- Air intake preheater systems — handles warm air on engine intake preheat lines and cold-start assistance units.
- Generator sets and industrial equipment — ventilation and hot air discharge on generator enclosures, industrial heater outlets and equipment cabinets.
- Marine, caravan and RV installations — flexible warm air ducting for boats and caravans, plus protection of cable runs, coolant tubes, fuel lines and other heat sensitive parts.
Key Features & Benefits
- Material options for every budget — aluminum foil reflects radiant heat, glass fiber fabric improves heat resistance and reinforcement strength, black PVC gives a clean appearance, and kraft paper is the economical choice for standard heater duct work.
- Corrugated flexible structure — the hose bends easily in compact installation spaces without restricting airflow, which shortens installation time on vehicle and equipment assembly lines.
- Lightweight and easy to cut — supplied by the metre and cut with a sharp knife, so installers work faster and waste less material on site.
- Built for B2B supply — stable dimensions, consistent wall build and repeatable quality make this diesel heater air duct hose suitable for OEM production, aftermarket distribution and fleet repair programs.
