Lightweight, Heavy-Duty Heat Protection

Thermaflect Sleeve provides high-performance radiant heat protection in a lightweight, flexible design. It reflects up to 90% of radiant heat (ASTM F1939 & MIL-C-24929A certified). Use it on air intake charge pipes to lower intake temps, improve fuel efficiency, and reduce emissions. It also protects wiring, fluid lines, and hoses from heat damage in harsh environments. Custom options are available for OEMs in heavy equipment, robotics, fire apparatus, and defense industries.

What do ASTM F1939 and Mil-C-24929A mean?

ASTM F1939 is a standardized test method for measuring the radiant heat resistance of materials, simulating high-temperature conditions. Mil-C-24929A is a military specification that outlines performance criteria for protective sleeving used in aircraft and military vehicles. These certifications ensure the sleeve meets rigorous standards for thermal protection and durability.
