Typical Applications
Industry gold standard for motorsport. PTFE is chemically inert — compatible with virtually all fluids. Smooth bore variant flows better; convoluted bore is more flexible.

Important Notes
Safety Factor: Working pressure is rated at 4:1 below burst. For brake and clutch lines, always verify with the manufacturer datasheet and your sanctioning body's regulations.
Bend Radius: Minimum bend radius is the centerline radius. Tighter bends collapse the hose ID and reduce flow — use swivel fittings or larger-radius routing wherever possible.
Temperature: Peak temperature ratings assume the hose is not under maximum working pressure simultaneously. Route away from exhaust and turbo housings, or use heat sleeving.
Fluid Compatibility: Always confirm compatibility with the specific fluid formulation (e.g., E85 percentage, specific brake fluid DOT rating). When in doubt, use SS PTFE — it is chemically inert with virtually all motorsport fluids.
