-3 St. Alum. Hose End

The -3 St. Alum. Hose End by EARLS is a precision Speed Seal straight hose fitting designed for high-performance fluid transfer systems in racing, marine, and industrial applications. This 3 AN (Army-Navy standard) hose end connects 3 AN hose to 3 AN female ports with a secure, leak-free design that eliminates the need for traditional crimping. Compact and lightweight at just 0.02 lbs, this aluminum fitting is engineered for users who demand reliability under pressure and vibration.

Constructed from aluminum and finished in blue and red anodized coating, the -3 St. Alum. Hose End utilizes EARLS' proprietary Speed Seal technology for rapid, tool-free installation and superior sealing performance. The straight configuration minimizes dead volume and turbulence, making it ideal for fuel delivery, coolant circulation, and hydraulic applications where flow efficiency matters. The anodized surface provides corrosion resistance while maintaining aesthetic appeal in engine bays and visible installations. The Speed Seal mechanism employs a cone-and-thread interface that ensures repeatable, vibration-proof connections without hardware removal.

This fitting is ideal for custom fuel systems, supercharger plumbing, transmission coolers, and any application requiring 3 AN hose termination. Users benefit from simplified maintenance—the Speed Seal design allows quick disconnect and reconnect cycles for system servicing. Compatibility spans any system using standard 3 AN female ports; verify hose inner diameter matches -3 specification before purchase. Installation requires only hand-tight connection with the hose; no torque wrench or specialized tools needed, reducing assembly time on the bench or in the vehicle.
