High Temp 550°F 2-Ply Silicone Brake Duct Cooling Hose - 3.00" I.D (10 feet)

Silicone Rubber Air Duct Hose is popular for brake cooling ducts due to its high temperature capability (maximum 550° F continuous)

This hose is extremely flexible and pliable, but a bronze coated spring-steel wire support helix prevents it from collapsing.
The fiberglass fabric cover and fiberglass cord are both impregnated and coated with silicone rubber.
Lengths can be screwed together to form a continuous length if you've got left-overs around.
