Radiator hoses routed near exhaust manifolds, turbos, or tightly packaged engine bays absorb radiant heat that accelerates rubber degradation and drives up coolant temperatures. The Lava Hose Sleeve from Heatshield Products wraps radiator hoses in volcanic rock-based fiber, blocking that heat at the source and extending hose service life.
Volcanic rock fiber outperforms fiberglass. The lava rock-based construction is 25% stronger than fiberglass and resists not just heat but also chemicals, fluids, and acids that collect in a working engine bay. Continuous exposure up to 1200°F and intermittent spikes up to 2000°F fall well within the sleeve's rated range.
Expandable braid fits over real-world plumbing. The woven sleeve expands up to 15% beyond its nominal inside diameter, so it slides over bends, terminals, and fittings without cutting or disassembling hose runs. Once positioned, two included heat shrink seals lock it in place for a clean, rattle-free finish.
A secondary benefit in tight engine bays. By containing radiant heat around the hose, the sleeve also reduces heat soak into surrounding intake plumbing, which helps lower intake air temperatures in densely packaged engine compartments.
