High Temperature Silicone 2-ply Air Duct Hose, Orange

View Catalog Page in PDF format

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.

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.

I ordered this for brake ducting, and this double wall hose stays straighter without sagging, resulting in smoother airflow with less need for tie wraps and less risk of rubbing on suspension components, or wearing through.

Good tubing

By John

from Annapolis

Verified Buyer

Comments about High Temperature Silicone 2-ply Air Duct Hose, Orange:

We use this tubing to direct air flow directly to the front brake pads. It is just flexible enough for making relatively sharp bends yet strong enough to withstand abuse.

Bottom Line Yes, I would recommend this to a friend
