Frequently Asked Questions
What is a Diesel Heater Port?
A diesel heater port is a wall-mounted pass-through that allows you to bring hot air from an external or portable diesel heater into your truck camper, van, trailer, or workshop. It provides a clean, safe, weather-sealed opening for a 3” heater hose.
What size hose does this port fit?
This port is designed to work with a 3.5" / 90mm diesel heater hose. We offer adapters to fit 3" / 75mm and proplex / 60mm sized hoses.
Is this product heat resistant?
Yes. It is printed from PET-CF (carbon-fiber reinforced PET), which can withstand up to 205°C. Diesel heaters typically output around 90–95°C, well within the safe range.
Is this Diesel Heater Port weatherproof?
Yes. We include a "rubber style" gasket with every kit. The hinged and magetic latching lid helps protects against rain, snow, dust, and road spray when the port is not in use.
Can I install this port on any flat surface?
Yes — the port mounts cleanly to truck campers, vans, trailers, teardrops, sheds, and any flat wall surface including aluminum, fiberglass, wood, and composites.
Is installation difficult?
Installation takes 20–45 minutes. Cut the circular opening with a 3" Hole Saw, drill the mounting holes with a 1/4" drill bit insert the port, and secure it with the provided hardware. Only basic tools are required.
Does the kit include the hose adapter?
Yes. The kit includes a 3” or a 3.5" twist-lock hose adapter, main port assembly, exterior mounting plate, threaded lid, and stainless hardware.
Will this work with portable diesel heaters?
Absolutely — this port is made for users who run their diesel heater outside the camper and pipe hot air inside safely and cleanly.
Is this compatible with all diesel heater brands?
Yes — works with Vevor, Planar, Hcalory and other Chinese diesel heaters (2kW, 5kW, 8kW), and any system with a 3” or 3.5" hot air outlet.
Can I close the port when not in use?
Yes — the magnetic latching lid keep out weather, bugs, and debris when the heater is not connected.
