Hi-Tech Duravent Flex-Flyte® L-9 Ducting Hose is a lightweight, high-temperature ducting solution designed for reliable air flow and fume removal in demanding applications. Constructed with 2-ply fiberglass and coated with silicone, it withstands temperatures from -75°F to 500°F. The helically wound spring wire, embedded between the two plies, ensures flexibility and prevents kinking. Rated at 11 PSI and featuring a smooth interior for optimal airflow and minimal friction loss, this brick-red hose is ideal for hot air transport, pellet drying, lavatory waste fume extraction, pre-launch fuel venting, and aerospace applications. Its durable, UV- and weather-resistant design makes it suitable for both indoor and outdoor environments.
