Diesel heater duct connector splits warm air into two runs, helping you direct heat where it’s needed and reduce uneven cabin temperatures. This 75mm 3-way Y branch duct connector uses two 90° rotatable valves to manage airflow between outlets for tighter heating control in vans, RVs, trucks, boats, cabins, and workshops. Built from polypropylene with TPE, it’s designed for stable performance under heat and frequent adjustments.

Use this Y branch duct connector when you need flexible air routing—send more heat to the sleeping area, footwell, or work zone, then adjust as conditions change. The compact, lightweight design helps keep duct runs organized, while the rotating valve flaps make fine-tuning airflow straightforward during installation and everyday use. Confirm your duct diameter and heater outlet compatibility before ordering, then grab yours today and finish your diesel heater ducting setup with cleaner airflow control.
