About This

• Important Installation Notice – Do NOT connect directly to the heater’s hot air outlet; always attach this hose to the Outlet air exhaust duct end instead.
• High-Heat Stable Nylon – Unlike PVC hose, nylon ducting stays stable under continuous high temperatures without softening or melting.
• Flame-Retardant Surface – Treated outer coating helps slow flame spread and improves safety in high-temperature airflow paths.
• Flexible & Long-Lasting – Woven nylon resists cracking, tearing and kinking, delivering longer service life than foil or PVC hoses.
• Universal 3” Compatibility – Fits most 5KW/8KW diesel parking heaters to route warm air into cabins, vans, RVs and boats.
