With a temperature range of -70C to +300C, these silicone glass coated brake duct hoses direct air from front mounted air ducts to spindle ducts for brake cooling. They are extremely flexible and pliable, but also feature a spring steel wire with an external filament fibreglass cord support to help prevent hose collapse during use. Proflow's brake duct hoses are available in a range of different sizes to suit your specific application.
