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.
