Cold mornings hit hard.
Should you be in a cabin, workshop, RV, or out camping, everyone knows the feeling of waking up in the cold. This adapter turns your diesel heater from a standalone box of warm air into a modular heating system.

It converts the 3" / 75mm outlet on your heater to standard 4-inch ducting, giving you quieter airflow, longer reach, and easier routing. Made from carbon fiber strengthened polycarbonate the adapter stays rigid under continuous heat, vibration, and real-world abuse—no sagging, no warping, no surprises.

Compatible with most major 4kW–8kW diesel heaters.
The adapter is a simple push-fit onto the heater housing. Add a hose clamp (not included) and lock in any standard 4-inch dryer hose. Designed as part of a modular ecosystem. Pair it with the VentLink pass-through and the 12V DC power station adapter for a complete, field-ready heating setup.

Variations: Select at Checkout
Heat-link classic: Simple Push to fit connection

Designed for those who live off the beaten path.
Proudly made and tested in the Pacific Northwest, USA.
