Diesel Heater 75mm Y Duct Splitter, Dual Rotating Valves

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.

• Delivers controlled airflow with two 90° rotatable valves to aim heat to one or both outlets


• Fits 75mm (2.95") heater ducting for common 2kW, 5kW, and 8kW diesel air heater setups


• Improves distribution by splitting a single warm-air line into a compact Y-branch outlet


• Installs quickly with a simple Y-shape layout for clean routing in tight spaces


• Resists heat wear using durable polypropylene with TPE for long-term use

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.
