Silicone Rubber Air Duct Hose is popular for brake cooling ducts due to its high temperature capability (maximum 500° F continuous / 600° F intermittent). The 2-ply construction withstands higher pressure and vacuum than our Single-Ply Silicone Air Duct Hose (Part No. 3621), so it is popular as engine intake plumbing on normally-aspirated applications. 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. Lengths can be screwed together to form a continuous length if you've got leftovers around. Red-orange only.
Defects range from slight kinks, to small cuts, to pieces cut to odd lengths. All are easily repairable, or you can cut smaller pieces from it and save. Save over 25% on these factory blems. This item will not be backordered. For more like it, see our first-quality Silicone Air Duct Hose, Part No. 3631.
