Ummickl Heat Sleeve for Spark Plug Wires & Fuel Lines, Titanium 3/4" ID ×10ft — 2500°F Protection

Ummickl's titanium basalt heat sleeve is a flexible, cut-to-fit wrap that shields spark plug wires, fuel lines, brake cables and wire looms from extreme radiant heat up to 2500°F.

High under-hood temperatures can damage wiring, melt hoses and cause vapor lock. This 3/4" inner-diameter, 10-foot roll of basalt-based titanium heat sleeve is engineered to reduce radiant heat by roughly 80% while remaining thin, expandable and easy to fit around cables, hoses and connectors. It’s intended as a protective barrier where clearance is tight and traditional bulkier shields won't work.

How does this heat sleeve reduce engine bay heat exposure?

The sleeve is woven from high-temperature basalt fibers with a titanium reflective layer that repels radiant heat and withstands intermittent exposures up to 2500°F. It acts as an insulating and reflective barrier, lowering the heat that reaches sensitive components.

• Reduces radiant heat transfer by about 80%
• Titanium-reflective outer layer disperses infrared heat
• Basalt core resists higher temperatures than fiberglass options
• Maintains flexibility for curved routing and tight spaces

Will it fit my wires, hoses and spark plug boots?

This wrap is built to be versatile: the 3/4" inside diameter expands and contracts to clear terminals, boots and fittings while remaining snug enough to stay in place. You can trim the roll to exact lengths, making it suitable for individual wires or longer harness runs.

• 3/4" nominal inside diameter with expandable weave
• Cut-to-length roll — customize per component
• Compatible with straight, 45° and 90° boots when trimmed properly
• Thin profile preserves clearance in tight engine bays

How easy is installation and maintenance?

Installation requires only basic hand tools: slide the sleeve over the wiring or hose and trim to fit, then secure ends with clamps, ties or high-temperature tape. The material resists fraying and stays flexible for rerouting or future maintenance.

• Simply pull wires/hoses through the sleeve and cut to fit
• Works around connectors thanks to expandable weave
• Can be anchored with clamps, stainless ties or heat-resistant tape
• Low-profile design simplifies service access and inspection

What specific components does it protect and against what risks?

Primarily designed for spark plug wires, the sleeve also shields fuel lines, brake lines, clutch cables, harnesses and other heat-sensitive parts from radiant and convective heat. By reducing heat exposure, it helps preserve insulation, fittings and fluid stability in close-clearance areas.

• Spark plug wires: prevents heat-related breakdown and arcing risk
• Fuel lines and hoses: reduces vapor lock risk by lowering surface heat
• Brake and clutch cables: protects polymer coatings from melting and glazing
• Wire looms and sensors: keeps connectors within intended temperature range

Who is this for? Mechanics, restoration enthusiasts and performance vehicle owners who need a slim, durable heat barrier for tight engine bay routing will find this sleeve useful. It’s also suited to DIYers upgrading exhaust shields, turbo inlet areas or custom wiring routes where space is limited and high heat resistance is required. Ummickl includes a 10-foot roll to cover multiple wires or longer runs and offers lifetime after-sale support if you need help with fitment or replacement.
