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 for automotive enthusiasts, mechanics, and daily drivers alike, this fireproof sleeve safeguards fuel, transmission, brake lines, and electrical wiring from damage caused by high temperatures and harsh conditions.
Whether you’re working on a street car, off-road rig, or race vehicle, the DEI Fire Sleeve delivers reliable heat protection to extend the life of your components and maintain vehicle safety. Its durable construction ensures long-lasting performance in demanding environments.
Key Features:
The DEI Fire Sleeve offers superior heat resistance and abrasion protection through advanced materials and design:
- Constructed from braided glass material that resists high temperatures and mechanical wear.
- Heavily coated with 100% iron oxide silicone rubber for enhanced fireproofing and durability.
- Provides continuous heat protection up to 500°F, withstanding intermittent heat spikes up to 2000°F.
- Ideal for insulating and bundling fuel lines, transmission lines, brake lines, wiring harnesses, hoses, and oil lines.
- Flexible sleeve design allows easy installation over existing lines and wiring.
- Measures 3/4 inch (0.75") in diameter and comes in a 25-foot length to accommodate various applications.
- Resistant to abrasion, chemicals, and environmental exposure for reliable long-term use.
- Helps prevent heat-related failures and improves overall vehicle safety and reliability.
Construction & Design:
The DEI Fire Sleeve is engineered with a braided glass fiber core that provides excellent thermal insulation and mechanical strength. This core is then coated with a thick layer of iron oxide silicone rubber, which enhances fire resistance and protects against heat damage. The combination of these materials ensures the sleeve can endure extreme temperatures and harsh automotive environments without degrading.
The sleeve’s flexible design allows it to conform to various shapes and sizes of hoses and wiring bundles, making it versatile for many automotive applications. Its durable coating also resists abrasion and chemical exposure, ensuring your lines remain protected even in demanding conditions.
Installation & Fitment:
The DEI Fire Sleeve is designed to fit most vehicle models and can be easily cut to length for custom applications. Its flexible construction allows for straightforward installation over existing lines and wiring without the need for special tools or modifications.
No cutting, drilling, or special tuning is required to use this sleeve. Simply slide it over the components you wish to protect and secure it as needed with clamps or ties.
- Fits most automotive fuel, brake, transmission lines, wiring, and hoses.
- Cut to desired length for a precise fit.
- Compatible with a wide range of vehicle makes and models.
What's Included:
- One 25-foot length of 3/4" diameter DEI Fire Sleeve
Ideal For:
- Automotive enthusiasts seeking to protect critical lines from heat damage.
- Mechanics and fabricators working on custom or performance vehicles.
- Off-road and racing applications where extreme heat exposure is common.
- Daily drivers looking to improve vehicle reliability and safety.
- Anyone needing a durable, fireproof sleeve for wiring, hoses, or fluid lines.

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!
