High Temperature Silicone Air Duct Hose, Orange

Click for a larger picture of High Temperature Silicone Air Duct Hose, Orange

Silicone Rubber Air Duct Hose is popular for brake cooling ducts due to its high temperature capability (maximum 450° F continuous / 500° F intermittent). 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 leftovers around. Red-orange only.

Note: These ducts are manufactured in 12 foot nominal lengths but only measure 12 feet when stretched tightly. The actual lengths will generally measure several inches less than nominal when relaxed.

Nice brake duct hose

Nice brake duct hose for a custom install on a street/track car. I was able to squeeze the hose and make it slightly oval to fit through a tight space in the wheel well. The hose held up well even after a little contact with the tire(only suffered cosmetic damage).

This is the product you want for custom brake cooling. The price is right and product fits the bill. The only better option would be a form molded apparatus but that's not in my budget.
