Ummickl Titanium Heat Shield Sleeve for Fuel Lines & Wires 1/2in ID 10ft — 2500°F Basalt Composite

Ummickl Titanium Heat Shield Sleeve is a 1/2" ID, 10-foot basalt/titanium composite wrap designed to protect fuel lines, spark plug wires, brake lines and cable looms from extreme radiant heat up to 2500°F.

This flexible, cut-to-fit heat sleeve combines basalt fibers and a titanium surface to block radiant heat and prevent nearby hoses, wiring, and cables from softening, charring, or vapor locking. It's a thin, expandable sleeve that slips over spark plug boots, hoses, and braided lines and shrinks somewhat for a snug fit, making it a practical retrofit for cars, trucks, and many motorsport or industrial applications.

How does this sleeve reduce heat exposure to wires and fuel lines?

The sleeve reflects and dissipates radiant heat away from sensitive components while providing a thermal barrier against convective heat. Its woven basalt core resists high temperatures and retains structural integrity where standard fiberglass wraps can fail.

• Reflective titanium-faced layer sends radiant heat outward.
• Basalt fiber core resists melting and maintains shape at high temps.
• Can reduce measured radiant heat exposure by roughly 80% in many installations.

Will it fit my spark plug wires, hoses, and cable bundles?

The sleeve is expandable and can be trimmed to length, so it accommodates straight and angled spark plug boots, braided hose ends, and cable looms. It’s supplied as a 1/2" internal diameter roll in a 10-foot length, allowing multiple short runs or one long wrap depending on your needs.

• 1/2" ID fits many common wire and hose diameters; stretches for snug coverage.
• Cut-to-length design works with 45° and 90° boots and straight connections.
• 10-foot roll gives enough material for several protected runs or a full harness.

How simple is installation and what tools are required?

Installation is straightforward: push the wires or hose through the sleeve and position it over the heat source. No specialized tools are required, though scissors or a utility knife to trim length and zip ties or high-temp clamps to secure ends are recommended.

• Slip-over or feed-through application — no adhesives needed.
• Trim with scissors or a knife for a custom fit.
• Secure ends with zip ties, stainless clamps, or high-temp tape for long-term hold.

What materials and temperature resistance does the sleeve offer?

The sleeve uses high-temperature basalt fibers with a titanium-like reflective outer layer to increase radiant heat rejection. It’s rated for intermittent exposure up to around 2500°F, making it suitable where short bursts of extreme heat are present.

• Basalt fiber core resists high continuous temperatures better than typical fiberglass.
• Titanium-style reflective surface reduces radiant heat transfer.
• Intermittent temperature resistance up to 2500°F; ideal for sporadic high-heat zones.

Who is this for? Installers, mechanics, performance vehicle owners, and DIYers who need a compact, high-temperature barrier for spark plug wires, fuel lines, brake lines, and cable looms will find this sleeve useful. It’s aimed at anyone wanting an easily trimmed, flexible, and highly heat-resistant protective wrap for automotive and light-industrial heat-management tasks. If you require dedicated thermal insulation for continuous ultra-high heat or pressurized hose wrappings, pair this sleeve with proper clamps, shields, or engine bay routing solutions for best results.
