High Temp Silicone 2-ply Air Duct Hose, 450F, Orange Only

Click for a larger picture of High Temp Silicone 2-ply Air Duct Hose, 450F, Orange Only

Our 2-ply Silicone Rubber Air Duct Hose is popular for brake cooling ducts due to its high temperature capability (maximum 500° F continuous / 600° F intermittent). Lower-temperature applications can use our Neoprene 2-Ply Air Duct Hose (Part No. 3630).

This hose is 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. A second layer of silicone covers the inside of the hose to reduce turbulence. The 2-ply construction also withstands higher pressure and vacuum than our Single-Ply Silicone Air Duct Hose (Part No. 3621), so this hose is popular as engine intake plumbing on normally-aspirated applications. Red-orange color only. This silicone duct hose is not made in any other color.

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.
