.69in ID Firesleeve

The .69in ID Firesleeve by AEROQUIP is a 10-foot hose and wire protective sleeve engineered for high-temperature environments where thermal protection is critical. Designed for technicians, mechanics, and engineers who work with hydraulic systems, fuel lines, and electrical wiring in engine bays and industrial applications, this firesleeve safeguards vulnerable components from radiant heat, open flames, and abrasion damage. The silicone/fiberglass construction provides dual-layer defense, combining flexibility with proven thermal resistance.

This .69-inch inner diameter firesleeve accommodates standard hose diameters and wire bundles within that range, making it ideal for 11/16-inch nominal hose routing. The silicone-fiberglass weave balances heat resistance with workability—silicone maintains flexibility across thermal cycles while fiberglass reinforcement prevents collapse under pressure or contact with hot surfaces. The bright red finish improves visibility during installation and maintenance, reducing the risk of accidental routing errors in complex engine compartments. A 10-foot length provides ample coverage for single-run protection or multiple shorter segments on a single vehicle or system.

This firesleeve is ideal for custom automotive builds, marine engine installations, agricultural equipment, and industrial hydraulic systems where hose routing passes near engine manifolds, turbochargers, or exhaust components. Installation is straightforward: slip the sleeve over the hose or wire bundle and secure with hose clamps or spiral wrap at intervals to prevent migration. AEROQUIP's reputation for durability ensures this sleeve will perform reliably in temperature-intensive environments, making it an essential upgrade for builders and technicians prioritizing system longevity and safety.
