Fire Sleeve .625in ID x 25ft

The Design Engineering Fire Sleeve .625in ID x 25ft provides critical thermal protection for sensitive automotive components exposed to extreme under-hood temperatures. This protective sleeving is essential for shielding fuel lines, oil lines, and wiring harnesses from the intense radiant heat generated by high-performance exhaust manifolds and turbochargers. By mitigating heat soak, it prevents vapor lock and protects electrical systems from melting or degrading over time. Professional builders and automotive enthusiasts use this sleeve to ensure long-term reliability in harsh racing or high-performance street environments.

Constructed from a high-grade fiberglass base and coated with a thick layer of iron oxide-impregnated silicone, the Design Engineering Fire Sleeve .625in ID x 25ft is engineered to withstand continuous temperatures up to 500 degrees Fahrenheit. The dense weave of the fiberglass interior provides structural integrity, while the silicone outer jacket sheds molten metal splash and resists chemical abrasion. This specific .625-inch inner diameter allows for a snug fit over 5/8-inch hoses, ensuring minimal bulk while maintaining maximum insulation. The included 16-inch fire tape allows for secure, professional-grade finishing at the ends of the sleeve to prevent fraying or fluid ingress.

This 25-foot bulk roll of Design Engineering Fire Sleeve .625in ID x 25ft is an ideal solution for comprehensive plumbing projects where multiple lines require uniform heat shielding. It is highly compatible with standard AN-6 hoses and various sensor wires found in modern engine bays. Installation is straightforward as the flexible material slides over lines before final assembly, and the black finish provides a discreet, factory-like appearance. This product is a necessary specification for any custom build requiring rigorous fire protection and advanced thermal management.
