Dometic 25' Insulated Flex R4.2 Ducting/Duct - 5"

The Dometic 25' Insulated Flex R4.2 Ducting/Duct - 5" is a heavy-duty climate control solution designed for mobile command vehicles, tactical operations centers, armored platforms, and emergency response units that require reliable HVAC distribution in challenging environments. Built to military and law enforcement specifications, this flexible ducting system maintains temperature and humidity control in confined spaces where traditional rigid ductwork cannot be installed. The 25-foot length provides extended reach for complex vehicle layouts, cargo containers, and field deployments where climate integrity is mission-critical.

This insulated flexduct features a round wire-reinforced core wrapped in mylar fabric shell construction, delivering R4.2 thermal resistance—a critical rating for vehicles operating in extreme temperature differentials. The 1-inch wall thickness of insulation prevents condensation buildup, maintains equipment operating temperatures, and reduces noise transmission during quiet tactical operations. The 5-inch diameter accommodates high-volume airflow without excessive turbulence, while the flexible construction allows routing around equipment racks, weapons systems, and tight spaces where rigid ducts would require costly rework or limit installation options.

Field operations, mobile command posts, and armored vehicle integrations benefit most from this solution, particularly in desert, arctic, and high-humidity environments where thermal regulation directly impacts equipment reliability and personnel endurance. Installation works seamlessly with Dometic HVAC systems and standard 5-inch ducting connectors found in tactical vehicle climate control packages. The lightweight 1-pound construction simplifies installation in weight-sensitive platforms without requiring reinforcement modifications, making it ideal for retrofit applications where adding traditional ductwork is impractical or cost-prohibitive.
