Designed with extra-thick, braided high-bulk glass fiber to protect your personnel from hot hoses and piping, while cutting your heat energy losses.

Best possible insulation properties
Cool Blue™ high temperature sleeve is designed to provide your personnel with effective protection against burns from flexible steam lines and hot hoses.

Beneath the heavy coating of our proprietary compound of cool blue silicone rubber, Cool Blue's braided interior layer is twice as thick as (and denser than) our heaviest grade of Aerostyle Pyrojacket® fire sleeve.

Heat transfer through the fire sleeve is gently dissipated, so that Cool Blue™ remains friendly to human touch even at elevated temperatures.

Note: The exterior coating will not adhere to human skin.

Excellent modulus of elasticity
Cool Blue™ can be used to bundle groups of hot hoses or tubes.

Performance rating
Depending on your operating conditions, Cool Blue™ firesleeve can reduce an outer temperature of 380 ° F (194°C) to approx: 130°F (54°C).

Insulflex® Cool Blue™ firesleeve can typically be installed on hose assemblies operating up to 600°F (316°C).
