Thread-On Sensor Bung Ad apter

The Thread-On Sensor Bung Adapter by Vibrant Performance is a precision threaded coupling designed for exhaust system diagnostics and oxygen sensor installation. This adapter bridges 18 mm x 1.50 male and female threads, enabling seamless connection between sensor bungs and exhaust ports on custom fabrication, performance exhaust systems, and engine tuning applications. Technicians and fabricators rely on this component to create flexible, reusable sensor mounting solutions that accommodate multiple gauge installations and diagnostic equipment.

Manufactured from stainless steel in a natural finish, the Thread-On Sensor Bung Adapter resists corrosion and thermal degradation in high-temperature exhaust environments. The matched 18 mm x 1.50 metric thread pitch on both ends ensures a secure, leak-free fit without requiring welding or permanent modification to exhaust components. Stainless construction delivers durability across repeated installations and sensor rotations, critical for systems undergoing frequent diagnostics or multiple sensor changes during engine calibration and testing.

This adapter is ideal for custom exhaust fabricators, engine builders, and performance shops managing oxygen sensors, air-fuel ratio gauges, and exhaust gas temperature probes. Installation is straightforward: thread the male end into an existing female bung or port, then attach your sensor or secondary adapter to the female end. Compatible with any component featuring standard 18 mm x 1.50 metric threads, it streamlines system modularity and supports both OEM diagnostics and aftermarket tuning equipment without permanent commitment to fixed mounting geometry.
