Endura Tube Sleeve #3

The Endura Tube Sleeve #3 by Russell is a precision-engineered protective component designed for automotive fuel and coolant line systems. Built for mechanics and enthusiasts who demand reliability under engine bay conditions, this tube sleeve shields vulnerable hose sections from abrasion, heat damage, and fluid degradation. Whether you're restoring a classic engine, upgrading a performance fuel system, or maintaining OEM specifications on a stock build, the Endura Tube Sleeve #3 provides essential protection where lines pass through frame rails, brackets, or high-temperature zones.

Russell's Endura sleeve technology features a durable, heat-resistant polymer construction that accommodates tubing without restricting flow or creating installation stress. The sleeve's compact 2.65-inch length and 1.65-inch inner diameter are engineered to fit standard fuel and coolant line applications across a wide range of vehicle platforms. The lightweight design—just 0.04 lbs—ensures zero impact on fuel efficiency or system performance, while the protective barrier prevents chafing damage that can lead to pinhole leaks over time. This component meets the durability standards expected in both street and performance applications.

Tube sleeves are essential for anyone running custom or aftermarket fuel systems, or for restoring vehicles where original line routing may expose hoses to sharp chassis edges or hot exhaust components. Installation is straightforward—slide the sleeve over the hose section requiring protection and secure with existing clamps or brackets. Mechanics frequently install Endura sleeves during fuel system upgrades, engine swaps, and restoration projects where preventative protection against system failures is non-negotiable. Compatibility spans domestic and import vehicles; verify your specific line diameter and routing before purchase to ensure optimal fit.
