A clean, secure solution for routing diesel heater ducting through a vehicle panel.
Designed to provide a safe, sealed passage for 3"/75mm heater ducting from inside the vehicle to the outside, or vice versa, whether to a roof tent, awning enclosure, or external living space.
Originally developed for my own Defender build, this port offers a professional, watertight panel penetration without the bulky or improvised appearance of traditional fittings. The result is a subtle, factory-style finish that looks OEM.
Designed and manufactured in-house from UV-resistant, high-temperature ASA. Durable and suitable for long-term use on expedition and daily-driven vehicles.

Panel-mount design for flat panels up to 10mm thick
