HeatLink - Ultimate Diesel Heater Port

Stay warm, stay protected, and stay adventurous with Heat Link—the universal diesel heater port designed for campers, overlanders, and ice fishers who demand performance and reliability in every environment.

BUILT FOR ALL SEASONS, ALL ADVENTURES
Whether you're in a camper, pop-up, topper, ice fishing hut, or tent, Heat Link is compatible with all major diesel heaters and 3" ducting to deliver consistent warmth. Made from durable, sun and weather resistant ASA 3D printed plastic, this low-profile port ensures a snug seal against snow, rain, dust, and pests—keeping you comfortable and secure in any condition. Unlike those other options, we utilize high quality buna O-rings to truly seal out the elements. No magnets to rust or fail in high winds here!

EXCLUSIVE PATENT-PENDING POSITIVE PRESSURE MODE
Heat Link’s patent-pending positive pressure mode takes air management to the next level. Lock the lid halfway closed allow air to flow. This mode pressurizes your space, keeping from entering the back of your camper while driving on dirt roads.
