Fire Shield Sleeve Black 3/8 in id x 3 ft Roll

The Fire Shield Sleeve Black 3/8 in ID x 3 ft Roll is a critical safety component for any serious boater, mechanic, or marine enthusiast who runs fuel lines, engine hoses, or electrical wiring in high-heat zones. Whether you're protecting fuel injection lines near a hot engine block, shielding hydraulic hoses from radiant heat, or safeguarding wiring in tight engine compartments, this fiberglass-silicone sleeve delivers reliable thermal protection where it matters most. Overheating fuel lines and exposed wiring are leading causes of onboard fires—this product eliminates that risk with proven heat-resistant construction.

Manufactured by HEATSHIELD PRODUCTS, the Fire Shield Sleeve is engineered from a fiberglass-silicone composite that withstands temperatures up to 500 degrees Fahrenheit, far exceeding typical engine compartment conditions. The 3/8-inch inner diameter fits standard fuel lines, brake hoses, and bundled wiring, while the 3-foot roll length provides ample coverage for multiple applications without waste. Installation is straightforward—simply slip the sleeve over your line or bundle before routing it near heat sources, or wrap it around existing hoses using the self-closing design. The black finish blends seamlessly into engine bays and resists UV degradation, ensuring long-term durability in marine environments where salt spray and sunlight accelerate corrosion and material breakdown.

This sleeve is ideal for inboard engines, outboard rigging, and any vessel where fuel, hydraulic, or electrical lines run near manifolds, turbochargers, or exhaust systems. Experienced anglers and boating professionals rely on HEATSHIELD products to prevent catastrophic failures during extended offshore trips or high-speed runs when engine temperatures spike. The lightweight design (0.25 lbs) adds negligible weight while eliminating insurance and safety liabilities. Stock the Fire Shield Sleeve in your marine maintenance kit for emergency repairs, or use it proactively during engine upgrades and winterization to extend the life of critical hoses and wiring. For 3/8-inch applications, this 3-foot roll is the professional-grade standard.
