#6 AN Plug

The FRAGOLA #6 AN Plug is an essential hydraulic and fuel system component designed for high-performance automotive applications where precision fluid management is critical. Whether you're building a race engine, upgrading a custom fuel system, or restoring a classic performance vehicle, this compact fitting serves as a reliable port closure solution. AN fittings have become the industry standard in motorsports and custom fabrication because they deliver consistent performance across extreme temperature ranges and high-pressure environments without leakage.

Built by FRAGOLA, a trusted manufacturer known for precision-engineered hydraulic components, this #6 AN plug features the brand's signature quality construction and reliable sealing integrity. The compact 3.3 by 0.6 by 3.9 inch profile and minimal 0.02 lb weight make it easy to integrate into tight engine bay layouts without adding unnecessary bulk or vibration concerns. The AN thread standard ensures compatibility with FRAGOLA's complete line of fittings, hoses, and adapters, allowing you to create a cohesive system that responds predictably under load.

Mechanics and fabricators rely on FRAGOLA plugs when sealing unused AN ports during custom fuel system builds, boost control systems, or auxiliary cooling circuits. This fitting is indispensable when rerouting lines or transitioning between different system configurations without leaving open ports that risk contamination or fluid loss. Proper installation with thread sealant or PTFE tape ensures leak-free operation over thousands of miles, making it a cost-effective safeguard for any precision automotive project.
