Heat Protection & Thermal Sleeving

Shield Your System from Extreme Engine Bay Heat

In the high-stress environment of a performance vehicle, managing heat is just as important as managing flow. At AN Fittings NZ, our Heat Protection collection is designed to shield your vital fuel, oil, and brake lines from the intense radiant heat generated by turbochargers, exhaust manifolds, and headers. Without proper thermal management, hoses can become brittle, fluids can boil, and the risk of localized fires increases significantly.

We provide professional-grade solutions, including the industry-leading Speedflow Fire Sleeve, to ensure your plumbing system remains cool, flexible, and functional—even under the most grueling racing conditions.

Advanced Thermal Barriers for Every Application

Our range of heat protection hardware is curated to offer varying levels of defense based on your proximity to heat sources:

  • Fire Sleeve (Silicone Coated Fiberglass): The ultimate in hose protection. Rated to withstand continuous temperatures of 260°C and intermittent flame exposure, this sleeve is essential for fuel lines running near exhaust components or through the cockpit.

  • Heat Reflective Sleeving: A lightweight, "slip-on" solution designed to reflect up to 90% of radiant heat. Ideal for protecting wiring looms, sensor cables, and oil lines from heat soak.

  • Heat Shielding Tapes: High-adhesion thermal wraps for protecting air boxes, firewalls, and larger diameter pipes where a slip-on sleeve isn't practical.

  • Spark Plug Boot Protectors: Specialized high-temp socks that prevent ignition leads from melting or "arcing" due to header proximity.
