Diesel Heater Pass Through Wall Port for 3″ & 3.5″ Hose Quick Connect to your Camper RV Van Heater Duct Vent – High Temp

Need a way to pass your diesel heater hose into your Truck Cap or RV/Camper? This port screws or rivets over a hole, and creates a quick connection for your hose, providing a twisting cap when not in use. The Wall Port & Cap are made out of high temp outdoor rated ASA material. The Hose Adapter is made out of a very high temp nylon to withstand temps up over 400F handling any consumer diesel heater. We’ve found the combine of these 2 materials give the port long outdoor life, while still handling very high temps. If you choose a larger or smaller hose size than the wall port size, you’ll receive an adapter to bridge the sizing differences.
