Enhanced Diesel Heater Passthrough Port Adapter for Roof Top Tents

The most secure 75mm tent vent adapter on the market. Most adapters struggle to stay in the zipper track, leaving you with gaps that let the heat out and the cold in. Our Enhanced Diesel Heater Passthrough is a purpose-built solution designed to lock into your tent’s window or door track and stay there.  Most commonly paired with 75mm 360* Heater Vents (not included).

3D printed from high-durability PETG, this adapter uses a specific geometry to maximize your tent's weather resistance while providing a rigid, reliable connection for your heater ducting.

Engineered for a Superior Seal:

• Enhanced Exterior Overlap: The oversized exterior flange is designed to lap over the tent fabric. By sitting on the outside of the tent, it creates a physical barrier against wind and rain that standard flush-mount adapters simply can't match.
• Integrated Zipper Reliefs: We’ve added custom U-notches at both the top and bottom of the zipper channel. This allows your tent zippers to seat fully into the adapter, closing the "eyelet" gap that usually exists at the ends of the track.
• Locked-In Stability: The deep-channel design is optimized to hold the zipper teeth securely under tension. Once you zip your tent window down into the reliefs, the adapter is locked in place and won't pop out, even in high winds.
• High-Temp PETG Construction: Built for the trail. Our PETG material is UV-resistant and heat-stable, ensuring it won't warp or soften from the constant thermal output of your 75mm diesel heater hose.
