Earl's Performance Swivel-Seal AN Hose End Fittings

Earl's Performance Swivel-Seal® Hose End Fittings are the industry benchmark in adjustable AN hose end technology, trusted by professional race teams and performance builders for decades. Earl's invented the self-indexing adjustable hose end in 1972, and the Swivel-Seal line remains the most reliable and widely sold premium adjustable AN hose end on the market — engineered as the definitive solution for rubber-lined braided hose plumbing systems.

Key Features:

• Aerospace-Grade Aluminum Construction: Manufactured from aluminum alloys that meet or exceed minimum requirements for aerospace hose end specifications, delivering the strength and durability demanded by competition and high-performance applications.
• Dual Plane Anti-Seepage Sealing System: Earl's original dual plane anti-seepage seal provides a robust, leak-free connection that maintains sealing integrity under sustained pressure across all operating conditions.
• 360° Post-Installation Adjustment: Stainless steel retention pins allow full 360-degree rotation and repositioning after the fitting is installed, making routing corrections fast and straightforward without disturbing the seal.
• Aerospace-Proven Nipple-and-Cutter Primary Seal: The nipple-and-cutter design has been aerospace-proven for over 55 years and used in competition applications for over 30 years, delivering unmatched primary sealing integrity at the hose interface.
• Optimized Bend Geometry for Maximum Flow: Precision-machined bent tube designs deliver excellent fluid flow capacity, minimizing restriction in fuel, oil, coolant, and other high-performance plumbing circuits.
• Direct-Thread Port Compatibility: Swivel-Seal hose ends thread directly into female ports, eliminating the need for intermediate adapter fittings and keeping plumbing layouts compact and clean.
• Independent Coupler Rotation: The coupler rotates independently of the hose end body, allowing full torque to be applied to the port connection while the hose assembly remains stationary — preventing hose twist and stress during installation.
• Precision Machined to Exacting Tolerances: Every component is precision machined for consistent fitment and trouble-free field performance across all configurations.

Swivel-Seal hose ends are engineered for use with Earl's Perform-O-Flex™, Pro-Lite 350™, Pro-Lite Ultra™, and Auto-Flex™ braid-protected hose lines, forming a complete and fully matched fluid transfer system. Use with other manufacturers' hose is not recommended. Available in a wide range of AN sizes, angles, and configurations to suit virtually any plumbing application in racing, performance street, and high-output motorsports builds.
