Hon&Guan 3" Diesel Heater Hose Kit — 2×8ft Flexible Nylon Ducts, 3ft Outlet & Adjustable Y Splitter for 5KW–8KW Heaters

Hon&Guan 3" Diesel Heater Hose Kit is a complete flexible ducting set designed to route warm air from 5KW–8KW diesel parking heaters, featuring two 8ft hoses, an adjustable Y splitter, outlet pipe, vents, and clamps for a fast, secure installation.

This kit provides the essential hoses and fittings to extend and direct airflow from popular diesel air heaters such as Webasto and Eberspacher equivalents. Built from laminated nylon mesh reinforced with steel wire, the ducting combines flexibility with strength so you can bend and position vents without kinking. The multi-layer construction tolerates typical heater outlet temperatures and minimizes odor during use, making it suitable for vehicles and small craft.

How does the Hon&Guan hose kit connect to my 5KW–8KW heater?

Installation is straightforward: attach the 3ft outlet pipe to the heater outlet, then run the 8ft flexible ducts to desired vents and secure all joints with the supplied clamps. The Y splitter lets you branch a single heater outlet into two ducts for distributed airflow.

• Includes two 8ft ducts for extended reach.
• One 3ft outlet pipe to mate with most heater outlets.
• Six metal clamps for tight, reliable seals.
• Adjustable Y splitter to balance or shut off airflow to one branch.

Will these hoses withstand continuous heater temperatures?

The hoses use a laminated, multi-layer fabric reinforced with steel wire to resist deformation and maintain airflow paths. Rated for continuous heat up to around 212°F (100°C), they are intended for standard diesel air heater exhaust and warm air delivery rather than direct contact with combustion gases.

• Multi-layer construction for thermal resistance.
• Steel-wire reinforcement prevents collapse when bent.
• Low-odor material formulation for enclosed spaces.

How can I control airflow to different cabin zones?

The kit’s adjustable Y splitter contains two valves that let you proportion airflow between branches or shut one side off entirely. Pairing the splitter with the included vents enables targeted distribution to footwells, bunks, or driver cabins without extra components.

• Dual adjustable valves provide flow control.
• Close one side to prioritize a single zone.
• Works with the two included air outlets for direct delivery.

What comes in the full Hon&Guan heater hose kit?

This bundle supplies the common parts installers need to route warm air quickly and neatly. Everything is sized and selected to fit most 5KW–8KW parking heaters and typical vehicle layouts, reducing the need to source additional fittings.

• Two 8ft flexible 3" ducts for long runs.
• One 3ft outlet pipe for the heater connection.
• Adjustable 3" Y splitter with dual valves.
• Two air vents/outlets and six metal hose clamps.

Who this kit is for: installers and DIY owners of trucks, RVs, campers, and boats who need a ready-to-install ducting solution for 5KW–8KW diesel air heaters. It suits anyone replacing brittle or undersized hoses, adding a second vented zone, or building a tidy, controllable duct run where flexibility, durability, and simple airflow control are priorities.
