Heater Duct Splitter
Sparks Overland Adjustable Duct Splitter
The Sparks Overland Adjustable Duct Splitter lets you heat two tents or separate spaces from a single heater — with full control over airflow.
The adjustable dial allows you to send more heat where it’s needed most or balance airflow evenly between both outputs.
Our updated Y-shaped design improves airflow over traditional T-splitters, reducing restriction and preventing fan backup for smoother, more efficient heater performance.
Simple. Efficient. Built for cold nights.
Compatible with 3” (75mm) heater ducting.
