3inch Coupler
🔩 NomadCoupler – 3-Inch (74mm) Magnetic Hose Adapter
More Flow. More Heat. Same Snap.
When you're pushing serious BTUs through your tent setup, you need gear that can keep up. The NomadCoupler – 3-Inch is built for high-output diesel heaters (5kW–8kW) and designed to connect your heater ducting to your NomadPort passthrough with a solid, magnetic lock — no zip ties, no duct slippage, and no leaks.
With a rugged ASA magnetic ring and a high-temp PAHT-CF (carbon fiber-reinforced nylon) collar, this field-tested coupler handles serious heat while delivering maximum airflow.
🔑 Key Features
🧲 Snap-Fit Magnetic Mount
Connects directly to your NomadPort passthrough using embedded neodymium magnets. Auto-aligns and locks in with a satisfying click — no tools needed.
🔥 High-Temperature Collar
The duct-facing collar is made from PAHT-CF, a high-performance carbon fiber nylon engineered to resist warping, softening, or degradation under constant heat.
🔩 Clamp-On Duct Fit
Accepts standard 3-inch heater ducting and is clamp-ready (hose clamp not included). The collar allows for smooth rotation while maintaining a secure hold.
🌦️ Built for the Elements
The ASA ring is UV-stable, impact-resistant, and ready for long-term outdoor use. Together, the materials are built to thrive in harsh environments.
🔄 Part of the Modular System
Fully compatible with NomadPort, NomadCap, and other accessories for a seamless magnetic heating or ventilation setup.

⚠️ Safety & Responsibility
This is a ducting accessory. It is not a heater, not a combustion or exhaust component, and not a certified safety device. It does not make any heater safe to run in or near an enclosed space.
- Always follow your heater manufacturer's instructions.
- Keep heater exhaust outside the tent and away from fabric.
- Maintain proper ventilation and run a working carbon monoxide detector any time a heater is used in or near an enclosed space.
- Duct and adapter surfaces get hot in use. Keep them clear of fabric, bedding, gear, and skin.
- Secure all duct connections before running the heater, and check them each time you set up.
- Adult installation and supervision required.
