#8 Port Plug 3/4-16 Black

The #8 Port Plug 3/4-16 Black from FRAGOLA is a precision hydraulic and fuel system fitting designed for professionals and enthusiasts who demand reliable, leak-free connections in high-performance applications. This port plug serves as a closure component for AN-series fluid lines, sealing unused ports in custom fuel systems, cooling circuits, and hydraulic assemblies. By providing a secure, vibration-resistant seal, this fitting eliminates the need for temporary plugs or improvised solutions, ensuring system integrity during operation and storage.

Engineered from aluminum and finished with black anodizing, the #8 Port Plug features an O-ring seal that conforms to AN standard specifications for the #8 (1/2-inch) line size, with a 3/4-16 thread pitch for secure installation. The hex head design allows for controlled torque application using standard wrenches, preventing over-tightening while maintaining consistent clamping force. The O-ring creates a positive seal without requiring thread sealant tape, reducing assembly time and the risk of particle contamination in sensitive fuel or hydraulic systems. Black anodizing provides corrosion resistance and a professional appearance suitable for engine bays and visible installations.

This fitting is ideal for custom fuel system builders, drag racing platforms, and performance cooling system installations where AN-series fittings are the industry standard. Mechanics and fabricators benefit from its compatibility with the extensive FRAGOLA line of adapters and manifolds, ensuring seamless system integration. The lightweight aluminum construction (0.04 lbs) makes it suitable for weight-conscious applications without sacrificing durability. Installation is straightforward: thread into the AN port with hand pressure, then apply controlled wrench torque until the O-ring compresses for a watertight seal.
