Fuel lines, oil lines, and wire looms already routed through a hot engine bay present a real problem: you cannot sleeve them without disconnecting everything first. The Heatshield Products Thermaflect Sleeve with Hook and Loop closure solves that by splitting lengthwise, wrapping around any line or loom already in place, and securing with a hook and loop seam, no disassembly required.
Reflects up to 90% of radiant heat. The lightweight silver and chrome fiberglass construction bounces radiant energy away from protected lines and wires, holding a continuous rating of 1,100°F (593°C) and an intermittent rating of 2,000°F (1,093°C). Maintaining at least one inch of air gap between the sleeve and the heat source maximizes that 90% reflectivity figure.
Tested to recognized standards. The sleeve meets ASTM F1939, the standardized radiant heat resistance test method, and Mil-C-24929A, the military specification for protective sleeving used in aircraft and military vehicles. Those certifications confirm thermal protection performance beyond typical shop claims.
Protects fuel systems and wiring alike. By keeping radiant heat off fuel lines, the sleeve prevents vapor lock and reduces fuel evaporation. On intake tubes and intercooler pipes it helps hold intake air temperatures down. On wire looms it guards insulation from heat-soak damage. Available in inside diameters from 1/2 inch through 5 inches and lengths from 6 inches to 10 feet, the sleeve fits a wide range of applications in high-performance and daily-driven vehicles.
Removable and serviceable. The hook and loop seam lets you open, inspect, and reclose the sleeve during routine maintenance without cutting or replacing it. If airflow around the sleeve is limited, sealing the ends with hook and loop closure, HP Shrink, or clamps prevents heat from entering at the terminations.
