High-Temperature Coated-Fabric Hose for Motorsports and Automotive
The Heat-Flex Raceflex is a coated-fabric hose built to handle the heat loads of motorsports, automotive brake ducting, and transmission cooling. The temperature-rated construction with a spring steel wire helix holds up to radiant heat from engine bays, brake rotors, and drivetrain components where standard air-handling hose would fail. Flexible enough to route through tight engine compartments and chassis tunnels.
Where the Raceflex Fits
This hose is the right call for brake cooling duct on race and track-day vehicles, transmission oil cooler ducting, engine bay fresh air intakes, and fume extraction around hot components. Any automotive or motorsports application where ambient temperatures exceed what standard coated-fabric hose can handle is a candidate.

The Raceflex is our motorsports-specific high-temp hose. For industrial high-temperature applications like foundries, manufacturing, and metalworking, the Heat-Flex GS is a silicone-coated fiberglass alternative with broader industrial use.
Choosing the Right Size
Match the ID to your ducting outlet — most brake ducts on production and race vehicles run 3"–4" ID. Transmission coolers vary by application; check your cooler's inlet and outlet spec before ordering. Route with gentle bends away from direct exhaust contact, and secure with high-temperature clamps rated for the installed environment.
