The Tent Heater Duct Pass-Through Adapter Port is designed to route warm or cool air into a tent through a zippered opening while helping reduce gaps around the duct.
Instead of feeding duct hose through a loose zipper opening, this adapter creates a cleaner, more controlled pass-through point for your tent setup. The near-90-degree angled design helps prevent hose binding and reduces unnecessary stress on the zipper compared to straight pass-through adapters.
A clip-in vent insert allows you to direct airflow straight, left, or right inside the tent, giving you more control over where heated or cooled air is delivered.
This adapter is ideal for rooftop tents, ground tents, truck bed tents, hunting shelters, and other enclosed setups with a compatible zipper opening. Whether you are routing warm air from a heater or cool air from a fan or portable AC-style setup, it helps keep the duct path cleaner, more secure, and better managed.
Available in 3-inch and 4-inch inlet sizes to match common heater, fan, and air ducting setups. Select the inlet size that matches your duct hose.
Available in multiple color options to better match your tent, gear setup, or personal preference.
The adapter is made from ASA, a heat- and weather-resistant plastic chosen for outdoor tent and camping use. ASA offers improved durability in warm-air ducting applications compared to lower-temperature plastics.
Important: This adapter is intended for air ducting only. It is not for exhaust routing. If used with a fuel-burning heater, always keep the heater and exhaust system outside the tent, follow the heater manufacturer’s safety instructions, and use a working carbon monoxide detector.
