-8 Welding Bung 3/4

The -8 Welding Bung 3/4 is a precision aluminum weld-on fitting designed for high-performance hydraulic and fuel system applications where reliable sealing and permanent installation are critical. This 8 AN female O-ring bung serves as a sealed port adapter, engineered for builders and fabricators who need robust integration into custom manifolds, tanks, and line routing systems. Its weld-on design eliminates the need for threading, making it ideal for situations where welded attachment provides superior strength and leak-free performance over mechanical fasteners.

Constructed from natural aluminum, this bung features an integral female O-ring port sized to AN8 specifications, ensuring compatibility with standard -8 hydraulic hose fittings and adapters. The weld-on collar design distributes stress evenly across the mounting surface, providing structural integrity under pressure cycles common in racing, aerospace, and industrial hydraulic systems. The natural aluminum finish can be easily anodized or painted for corrosion protection in demanding environments, while the compact footprint (2.7 x 1.45 x 4 inches) allows flexible positioning in tight installation spaces.

This fitting is essential for custom build projects including race car fuel systems, hydraulic brake line installations, and aftermarket cooling or boost control circuits. Fabricators and engine builders rely on welded bungs to eliminate vibration-induced leaks that can occur with threaded ports in high-vibration environments. Installation requires TIG or MIG welding to a compatible aluminum or steel surface; proper weld penetration ensures maximum reliability and safety. The 0.1 lb weight and compact design make it suitable for weight-conscious builds where every component must justify its presence.
