HVAC Heater Hose
AAASTAND® HVAC heater hoses are constructed from high-temp EPDM or silicone rubber, reinforced with aramid or polyester fiber braids, for heat, pressure, and coolant compatibility, molded to OE routing geometry with formed bends, quick-connect ends, or multi-branch Y/T shapes for direct-fit installation.
AAASTAND® HVAC heater hoses circulate engine coolant to the vehicle’s heater core, enabling warm air delivery to the passenger cabin during cold conditions. Designed to resist electrochemical degradation (ECD), abrasion, and thermal fatigue, offered as individual hoses or integrated assemblies with snap-fit couplers, clamps, or insulation sleeves.
