Matching a heater duct hose to the right application means understanding temperature limits, insulation needs, and airflow requirements. Our FX-400 handles construction heater ducting up to 400°F, while the FX-550 is rated for exhaust service to 550°F. For portable cooling and temporary AC, the Springflex Arctic Duct 3 delivers R-4 insulation with 5:1 compression for easy transport and storage. The Heat-Flex line covers everything from event tent HVAC and dehumidification to chiller hookups and humidity control, with options in silicone and coated fabric that resist heat degradation over thousands of hours. Need a hot air blower hose for a diesel heater? The FX-180 handles forced-air heating at up to 180°F with a lightweight, compressible design. Every hose in this collection is built for repeated heating and cooling cycles — flexible enough to route through tight spaces, tough enough to hold up job after job.
