Upgrade or repair the ventilation on your portable diesel heater with this complete ducting kit from VEVOR. It includes everything you need to properly route warm air and exhaust: a 75mm (about 3-inch) diameter warm air duct hose (23.6-27.6 inches long), a 1-inch diameter exhaust pipe (23.4-23.6 inches long), stainless steel clamps for both sizes to ensure secure, leak-free connections, and a TPE tee connector for splitting the airflow if needed. All components are brand new and designed for durability. The kit is perfect for DIY installations in vans, sheds, workshops, or garages where you're using a diesel heater for supplemental heat. Proper ducting is crucial for safety and efficiency, directing heat where you want it and safely venting exhaust fumes outside. This kit makes the installation process cleaner and more professional. Always follow your heater's manual and local safety codes when installing heating systems.
