Silicone tolerates much higher temperatures, while EPDM hoses show a lower coolant evaporation rate for better cooling efficiency.130°C Both work well - choose by temperature and coolant loss priorities
EPDM vs silicone at a glance
Property EPDM hose Silicone hose Max temperature About -40°C—150°C 230°C (446°F), up to 270°C (518°F) special grades Coolant evaporation Lower - less evaporation, better cooling efficiency Higher evaporation rate Best for Standard cooling systems, cost-sensitive projects High-temperature and racing applications
