Union AN Male -10

The ALLSTAR PERFORMANCE Union AN Male -10 is a precision hydraulic and fuel line adapter designed for serious engine builders, custom fabricators, and performance mechanics who require reliability in high-flow applications. This -10 AN fitting is essential for custom fuel delivery systems, nitrous oxide lines, and coolant bypass circuits where rigid tube connections need to transition to braided hose or where multiple line segments require seamless joining.

Featuring a straight-through bore design, this male union maintains full flow capacity without pressure drop, which is critical when feeding fuel pumps or return systems at high volumes. The -10 AN designation indicates compatibility with a 5/8-inch inner diameter hose, supporting pressures typical of fuel injection systems and forced induction cooling loops. ALLSTAR PERFORMANCE's precision machining ensures concentricity and thread accuracy, preventing leaks at connection points.

This compact fitting is designed to fit tight engine bay configurations, while its aluminum construction keeps weight minimal—essential for weight-sensitive builds. Experienced fabricators and performance shops will appreciate the reliability and ease of installation this union connector provides in various applications.
