SCAT ducting is recommended for use in conducting extremely cold or hot air where temperatures range from -65°F to +550°F. It is lightweight and extremely flexible. This ducting minimizes waste because short sections which are normally unusable can be screwed together to form a continuous length. It is not recommended for negative pressure applications.
Scat Single Wall Aircraft Ducting
Fiberglass reinforced silicone on each end of the ducting
SCEET ducting is ideal for use in conducting extremely cold or hot air at temperatures ranging from -80°F to +550°F, and for conveying fumes. This ducting is highly flexible and can be easily installed around obstructions and sharp bends. It has less air-friction loss than similar non-lined ducting. SCEET ducting is not recommended for applications involving liquids or highly abrasive materials. It is not recommended for negative pressure applications.
Sceet Double Wall Aircraft Ducting
Fiberglass reinforced silicone on each end of the ducting
Scat and Sceet ducting are available in several configurations:
- No End Treatment
- Silicone Ends (Both)
- Silicone + 1 Beaded End
- Silicone + 2 Beaded Ends
A beaded end would go over a flange that has a bead on it or a lipped flange which has a lipped edge.
Additional Ducting Available:
- ITT Aerospace
- Venair ducting

Most Aircraft homebuilders are familiar with SCAT ducting, usually just called SCAT but sometimes incorrectly called SCAT tubing. SCAT is made from a single layer of red silicone-impregnated fiberglass. To keep the thin fiberglass material from collapsing, a spiral of high carbon steel wire is wound inside the duct. To keep the fiberglass in place on the wire, a string is wrapped around the ducting on the outside in the “valleys” between the wire ridges. If SCAT is used in an environment where moisture can get to the wire spiral, eventually the wire will rust. For that reason, you never want to use single-wall ducting for any engine induction system.
Engines have been damaged by rusted bits of SCAT wire getting into a cylinder! SCAT ducting can handle almost any temperature found on a typical homebuilt, except direct contact with an exhaust pipe. To move air in places where moisture may be present, use the double-walled ducting called SCEET for high-temperature use. An inner wall of silicone-impregnated fiberglass keeps water off the steel wire and provides additional strength to the ducting. Even though it costs a bit more, SCEET lasts a lot longer in service and is actually a better buy than SCAT for most applications.
High Temperature Silicone Aircraft Quality Ducting
Silicone is a synthetic compound with low amounts of thermal conductivity, chemical reactivity and toxicity. In its basic definition, silicone is an elastomer like rubber that is blended with carbon, hydrogen, and oxygen. This gives silicone ducting a high degree of chemical and thermal resistance. These resistant properties make silicone ducting perfect for a variety of ducting applications that involve the transferring of high temperature air and fumes. Custom Ducts offer selection of Aircraft quality silicone ducting to meet the demands of high temperature applications.
Our high temperature silicone ducting products are made by combining fiberglass into silicone to provide the ducting with both flexibility and high-temperature resistance. Our silicone ducting products feature excellent temperature ranges with hoses capable of operating as low as -65 degrees Fahrenheit and up to 550 degrees Fahrenheit.
Auto Racing Brake Cooling Scat Ducting
Silicone Rubber Aircraft Scat Ducting is popular for brake cooling ducts due to its high temperature capability (maximum 550° F continuous / 500° F intermittent). Lower-temperature applications can also use Custom Ducts single and double wall aircraft Scat and Sceet ducting.
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 color only. This silicone ducting is not made in any other color.
