AN Expander #6 Female x #8 Male

The AN Expander #6 Female x #8 Male from TRIPLE X RACE COMPONENTS is a precision hydraulic and fuel line adapter designed for high-performance racing, automotive fuel systems, and industrial fluid transfer applications. This straight-thread fitting adapter expands a #6 AN female port to accommodate #8 AN male connections, enabling system builders to transition between different line sizes without requiring complete reconfiguration. The swivel design reduces installation stress and prevents overtightening, making it essential for engines and systems where vibration and thermal cycling demand flexibility.

Constructed from aluminum and finished in black anodized coating, this adapter delivers corrosion resistance and a professional appearance while maintaining lightweight characteristics critical to racing applications. The anodized surface protects against oxidation in high-moisture or salt-air environments, ensuring long service life. The swivel connection design allows controlled torque application without transferring rotational stress to the main hose barbs or threaded ports, a feature that extends hose life and reduces leak points in pressurized fuel, coolant, and hydraulic systems. Weighing only 0.05 lbs, the compact form factor (1.8 x 1.05 x 2.75 inches) fits tight engine bays and tight spaces where weight and clearance matter.

This adapter is ideal for motorsports enthusiasts, professional race teams, and custom fuel system builders who require reliable step-up fittings for turbocharged engines, EFI conversions, and high-flow cooling loops. Its straight-thread design and swivel feature ensure leak-free performance under sustained pressure and temperature cycling. Installation is straightforward: thread the #6 AN female port into the component requiring expansion, then connect the #8 AN male line with proper thread-seal tape or approved sealant. Verify compatibility with your system's working pressure and fluid type before installation.
