Design Engineering Heat Sheath Aluminized Sleeving – 1-inch I.D. x 3 ft High-Temp Heat & Abrasion Protection for Hoses, Wires & Lines | Reflects Up to 2000°F

Overview

Design Engineering Heat Sheath™ Aluminized Sleeving blends robust 19 oz fiberglass insulation with a durable aluminized outer layer. This combination delivers reliable protection for hoses, lines, cables, and fluid paths that are exposed to extreme heat and heavy wear in automotive and industrial settings. The sleeving is designed to keep connections flexible and protected, even when conditions are demanding, helping components maintain performance over time.

Key benefits at a glance

• Extreme heat and abrasion resistance to guard hoses, fuel lines, wiring, and cables from wear and damage.
• Reflects radiant heat up to 2000°F while tolerating direct heat up to 500°F, supporting cooler operating temperatures.
• Protects against oil, chemicals, dirt, grease, and road debris typically found in busy automotive and industrial environments.
• Slip-on installation for fast service: disconnect, cut to length, slide on, and reconnect—no special tools required.
• Heavy-duty, fire-resistant construction with a fiberglass core and aluminized shell for durable thermal protection.

Material and durability

The 19 oz fiberglass insulation provides a resilient core, while the aluminized outer layer reflects heat and withstands exposure to high temperatures. The product is reinforced with aramid fiber thread, adding abrasion resistance and long-term durability without compromising flexibility. This design helps shield lines and components from oil, fuel, chemicals, dirt, and road grime, extending the life of critical systems.

Ease of use and real-world value

Designed for straightforward slip-on installation, Heat Sheath is well-suited for hands-on maintenance and field work. Its rugged construction is intended to endure demanding automotive and industrial environments, and it is proudly made in the USA. Note: do not apply directly to exhaust components, as the sleeve is not intended for contact with direct exhaust heat.

What you might experience

• Better protection for lines running near heat sources in engine bays or near high-heat machinery.
• Maintained flexibility of hoses and wires in cool-to-warm operating ranges due to heat reflection.
• Reduced risk of heat-related wear and external contamination from oil, fuel, and debris.

Whether you’re upgrading existing lines or mounting new assemblies, Heat Sheath offers a practical blend of heat resistance, abrasion protection, and ease of installation. Consider it as a possible option to help your lines stay protected and functional in tough environments.
