Overview:
The DEI Fire Sleeve is a high-performance thermal insulator designed to protect your vehicle’s critical lines and wiring from extreme heat and abrasion. Crafted from a durable braided glass material and coated with 100% iron oxide silicone rubber, this sleeve offers superior resistance to direct heat up to 500°F and intermittent heat spikes up to 2000°F. Whether you’re safeguarding fuel, transmission, brake lines, or electrical wiring, the DEI Fire Sleeve provides reliable, fireproof protection that enhances the longevity and safety of your vehicle’s components.
Ideal for daily drivers, performance enthusiasts, and off-roaders alike, this versatile sleeve helps prevent heat damage and abrasion, ensuring your vehicle’s vital systems remain intact under demanding conditions. With a generous length of 25 feet and a 5/8 inch diameter, it fits most applications and can be easily cut to size for custom installations.
Key Features:
The DEI Fire Sleeve combines advanced materials and thoughtful design to deliver exceptional heat protection and durability. Key features include:
- Constructed from high temperature resistant braided glass fiber for superior strength and flexibility
- Heavily coated with 100% iron oxide silicone rubber to provide fireproof insulation and abrasion resistance
- Protects fuel, transmission, brake lines, wiring harnesses, and other vulnerable components from heat and wear
- Withstands continuous heat exposure up to 500°F and intermittent heat spikes up to 2000°F
- Measures 0.625 inches (5/8 inch) in diameter, suitable for most hose and wire bundles
- 25 feet length allows for multiple applications or custom cuts to fit your needs
- Flexible sleeve design enables easy installation around complex routing paths
- Fireproof and abrasion-resistant coating enhances safety and component longevity
Construction & Design:
The DEI Fire Sleeve features a braided glass fiber core that provides excellent thermal insulation and mechanical protection. This core is tightly woven into a sleeve that maintains flexibility while resisting fraying and damage. The entire sleeve is then coated with a thick layer of iron oxide silicone rubber, a material known for its outstanding heat resistance and fireproof properties. This combination ensures that the sleeve can endure harsh engine bay environments, including exposure to flames, radiant heat, and physical abrasion.
The 5/8 inch diameter is a common size that fits most fuel, brake, and transmission lines, as well as wiring bundles, making it a versatile solution for a wide range of vehicles and applications. The 25-foot length provides ample material for multiple runs or larger projects, allowing you to customize the protection to your specific needs.
Installation & Fitment:
The DEI Fire Sleeve is designed for universal fitment and can be used on most vehicle makes and models. It is ideal for protecting lines and wiring in tight engine bays, undercarriages, or any area exposed to high heat or abrasion.
Installation is straightforward: simply cut the sleeve to the desired length and slide it over the hose, line, or wiring bundle you want to protect. Its flexible construction allows it to conform to bends and curves without compromising coverage.
- No special tools or modifications are required for installation
- Can be trimmed to fit any length or application
- Compatible with a wide range of automotive hoses and wiring
What's Included:
- One 25-foot length of DEI Fire Sleeve, 5/8 inch diameter
Ideal For:
- Protecting fuel, brake, and transmission lines from heat and abrasion
- Insulating wiring harnesses and electrical components in high-temperature areas
- Off-road vehicles exposed to extreme heat and rough conditions

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
