Aluminum Weld Bung 1/8in Female

The Vibrant Performance Aluminum Weld Bung 1/8in Female (VIB11170) is a precision-engineered threaded port fitting designed for systems that require a permanent, leak-free connection point. This weld-on bung provides a 1/8" NPT female thread, allowing integration of sensors, gauges, or auxiliary components directly into tubing or tank walls. Manufactured from lightweight aluminum with a natural finish, it delivers corrosion resistance suitable for automotive, fluid management, and industrial applications where vibration tolerance and structural integrity matter.

The 1/8" NPT female thread accepts standard metric and imperial port adapters, hose fittings, and instrumentation connectors. Aluminum construction keeps weight minimal while maintaining sufficient hardness for sustained use; the natural finish provides a baseline surface ready for anodizing, painting, or powder coating if additional corrosion protection is required. The compact weld flange design (3.5 x 0.55 x 5.95 inches) minimizes space consumption and allows precise positioning during installation. At just 0.02 lbs, it adds negligible mass to finished assemblies.

This fitting is engineered for engine builders, transmission specialists, cooling system integrators, and custom fabricators who need a permanent, vibration-resistant port for coolant temperature sensors, fuel pressure gauges, or vacuum distribution. The weld-on design eliminates threading into cast or aluminum bodies, avoiding the stress concentration risks that drilling introduces. It is particularly valuable in high-performance and racing applications where thermal cycles and engine vibration demand absolute reliability at every connection point.

Vibrant Performance is recognized in the automotive aftermarket for precision fuel and cooling system components. This weld bung exemplifies that focus on durability and compatibility, offering a straightforward, proven solution for integrating measurement and control ports into custom-built systems without compromising structural integrity or introducing leak paths.
