• High boiling point easily meets or exceeds U.S. FMVSS DOT 3 and DOT 4 wet/dry specialisation requirements
• High vapour lock temperature – greater protection against brake fluid vaporization
• Advanced corrosion protection
• High temperature stability
• Rubber swell control – contributes to efficient operation of the braking system components
