• Spiral reinforcement design provides exceptional burst strength and pressure resistance
• Excellent heat resistance for reliable performance in high-temperature engine environments
• Compatible with all common coolants and coolant additives
• OE-quality replacement for original equipment heater hoses

This heater hose is constructed using ethylene propylene diene monomer (EPDM) rubber compounds throughout, ensuring consistent performance and longevity. The spiral reinforcement layer prevents collapse under vacuum conditions while maintaining flexibility for proper routing. EPDM material resists degradation from ozone, weathering, and the full range of modern coolant formulations including extended-life and hybrid organic acid technology (HOAT) coolants.
