The materials used to make the “Speed-Flex 625” make it the ideal high temperature hose for taking air from the front of a car and directing it to the brakes in order to cool them. These racing ducts also feature a smooth bend radius and are heat reflective. When these features are combined with the hose’s flexibility, these ducts are a versatile choice for racecar ventilation.
The “Speed-Flex 625” high temperature hoses have an operating temperature that ranges from extreme lows to extreme highs. These flexible hoses can operate at temperatures ranging from -65 degrees Fahrenheit to +625 degrees Fahrenheit.
