Alm Female Weld Bung 10AN ORB

The MOROSO Alm Female Weld Bung 10AN ORB is a precision aluminum fitting designed for custom fuel system and fluid line applications in high-performance and modified vehicles. This component acts as a threaded port adapter, enabling fabricators and tuners to integrate auxiliary fuel delivery systems, surge tanks, gauge bungs, and bypass lines into welded aluminum bungs during engine bay construction.

Manufactured from lightweight aluminum, the MOROSO bung features a 10AN ORB (O-Ring Boss) female thread pattern, which accepts standard 10AN male fittings and hose ends commonly used in fuel injection and custom cooling circuits. The ORB design includes an integral O-ring sealing surface, which helps reduce leak potential under pressure cycling and vibration, eliminating the need for additional thread sealant.

This fitting is ideal for fabricators welding custom fuel systems for street rods, race cars, or late-model performance vehicles. Its compact design allows for integration into tight engine compartments without interfering with headers, intake manifolds, or other components, making it a reliable connection point for AN-rated hose assemblies.
