Heat Shield Sleeve Fuel Line Heat Shield Auto Hose Spark

Ummickl Titanium Heat Shield Sleeve is a flexible, 1" ID x 10' basalt-based wrap that blocks radiant heat and protects fuel lines, spark plug wires, brake cables and wire looms from extreme temperatures up to 2500°F intermittently.

When engine bay temperatures rise, sensitive hoses and wiring can degrade, melt, or suffer heat-induced failure. This Ummickl heat sleeve is woven from high-temperature basalt fibers and coated to resist radiant heat, offering a lightweight, cut-to-fit solution for protecting lines and cables near exhaust manifolds, turbochargers, or other heat sources. It reduces radiant heat transfer and is expandable to fit over boots and fittings while remaining thin and flexible for low-bulk installations.

How does this sleeve reduce heat exposure to wires and hoses?

The basalt-fiber construction reflects and resists radiant heat while providing thermal insulation. Rated for intermittent exposure up to 2500°F, it lowers heat transfer to underlying components and reduces the risk of vapor lock or insulation failure.

• Blocks roughly 80% of radiant heat to nearby components
• Basalt fiber withstands higher temperatures than common fiberglass wraps
• Thin, reflective coating improves thermal resistance without bulk

Can I install it over spark plug boots, AN fittings, or uneven connectors?

Yes — the sleeve’s woven, expandable design lets it stretch and contract around irregular shapes. You can thread wires, hoses, or fittings through the sleeve, then trim the length to suit each application for a neat, customized fit.

• Expandable weave fits over boots, clamps and angled fittings
• Easily cut with shears for customized lengths
• Thin profile preserves clearance in tight engine bays

What specific components should I protect with this heat sleeve?

Use it wherever heat can damage rubber, plastic, or electrical insulation: fuel lines, spark plug wires, clutch cables, brake lines, and bundled wire looms. It’s especially useful close to exhaust headers, turbo housings, and downpipes.

• Fuel lines and AN hose assemblies to prevent vapor lock
• Spark plug wires and boots to avoid melting or arcing issues
• Brake and clutch lines where heat transfer is a concern

How durable and maintenance-free is the Ummickl heat wrap?

The basalt weave combines high-temperature endurance with abrasion resistance for long service life under normal automotive conditions. While durable, the sleeve should be inspected periodically for physical damage after off-road use or heavy exposure to debris.

• High-temperature basalt fiber resists melting and charring
• Flexible and abrasion-resistant for long-term use
• Simple visual checks suffice; no special maintenance required

Who is this for: Enthusiast mechanics, DIY car owners, tuners, race teams and professional technicians who need a low-profile, high-temp thermal barrier to protect hoses, electrical wiring and lines in hot engine bays. The Ummickl 1" ID x 10' roll is ideal for targeted repairs or for protecting multiple runs of wire and hose where space is limited and reliable heat resistance matters.

Package includes one 10-foot roll of Ummickl titanium-style heat shield sleeve (approximately 1" inner diameter). Ummickl offers responsive after-sale support for installation questions and product concerns.
