AN Plug 6an (2pk)

The AN Plug 6AN (2pk) from EARLS is a professional-grade hydraulic fitting plug designed for high-pressure fluid systems in performance vehicles, racing applications, and industrial equipment. This two-pack set provides reliable port closure when AN hose lines are not in active use, preventing contamination and fluid leakage in critical fuel, coolant, and oil circuits. Whether you're building a custom cooling system, assembling a fuel delivery setup, or maintaining existing hydraulic infrastructure, these plugs deliver the dependable sealing performance that professionals demand.

Each plug features a hex head design machined from aluminum and finished in black anodize, combining lightweight construction with superior corrosion resistance. The 6 AN port size accommodates standard -6 hose fittings, creating a secure, leak-free seal that withstands pressure cycles and temperature fluctuations common in performance environments. Black anodized aluminum resists oxidation and maintains a professional appearance while reducing overall system weight—a critical advantage in racing and aerospace applications where every fraction of a pound matters. The hex head geometry allows easy installation and removal with standard wrenches, ensuring quick service access without specialized tools.

Buyers working with EARLS AN fittings—including those assembling fuel rails, transmission coolers, turbo lines, or nitrous systems—will appreciate this two-pack format for redundancy and convenience. The plugs are compatible with any standard -6 AN female port, making them essential spares for race teams, fabricators, and enthusiasts who value system integrity. Installation requires only hand tightening followed by light wrench torque to achieve proper seal; over-tightening should be avoided to prevent aluminum thread damage.
