#3 St. Hose End

The #3 St. Hose End by EARLS is a precision-engineered hose fitting designed for professionals and enthusiasts who demand reliable fluid transfer in high-performance applications. This straight hose end connector serves as the critical interface between AN hose lines and female ports, making it essential for fuel systems, hydraulic lines, and coolant circuits where pressure integrity and leak-free operation are non-negotiable. Built for durability and repeatability, the EARLS Speed Seal design eliminates guesswork during installation.

Manufactured from steel and finished in natural coating, this #3 AN hose end features a straight configuration that minimizes flow turbulence and maintains optimal pressure ratings across demanding circuits. The Speed Seal technology ensures consistent, replicable connections without the need for shims or adjustments—a hallmark of EARLS' engineering precision. The 3 AN to 3 AN female connection standardizes compatibility across AN-threaded component ecosystems, while the compact form factor (measuring 2.85 × 1 × 0.65 inches and weighing just 0.05 lbs) allows for flexible routing in tight engine bays and chassis spaces.

This hose end is ideal for custom fuel injection builds, drag racing fuel systems, and any motorsport or high-performance application requiring SAE-compliant AN fittings. Professional mechanics and fabricators trust EARLS fittings for consistent performance under sustained pressure and temperature cycling. Installation pairs seamlessly with 3 AN hose and female receiver ports commonly found in fuel rails, manifolds, and distribution blocks, making it a must-stock component for anyone maintaining or building serious automotive systems.
