3 Inch Diesel Heater Port

£65.00

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.

Features

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

  • Silicone O-ring’s for water and dust resistance

  • Custom snap-lock thread for secure, positive engagement

  • Standard 92mm mounting hole

  • Minimal, integrated aesthetic

Designed for Real-World Use

Developed to solve a practical problem, cleanly routing warm air from an internally mounted diesel heater to an external space such as a roof tent.

While originally designed around my Defender build, the port is universal and suitable for:

  • 4x4 builds

  • Campervans

  • Canopies

  • Expedition vehicles

  • Custom overland setups

Tech Specs

  • Material: UV-stable, high temp ASA polymer (Outdoor alternative for ABS)

  • Manufacturing: 3D printed

  • Panel thickness: Flat panel up to 10mm

  • Mounting hole: 92mm

  • Duct compatibility: 3" / 75mm

  • Seal type: Silicone O-ring’s
