Vibrant 10409 M12 x 1.25 Stainless Steel O2 Sensor Weld Bung

The Vibrant Performance 10409 oxygen sensor weld bung is designed for custom exhaust fabrication on motorcycles and other applications requiring M12 x 1.25 thread pitch. This precision-machined bung allows you to install an oxygen sensor at the optimal location in your exhaust system for accurate air/fuel ratio monitoring.

Key Features:

• M12 x 1.25mm thread pitch compatible with most motorcycle O2 sensors
• Constructed from high-quality stainless steel for corrosion resistance and durability
• Designed for permanent welding into exhaust pipes or headers
• Precision-machined threads ensure proper sensor fit and seal
• Compact design ideal for tight installations on motorcycle exhaust systems

This weld bung is an essential component for custom exhaust builds, turbo installations, or when relocating oxygen sensors for performance tuning. The stainless steel construction withstands high exhaust temperatures while resisting rust and oxidation. Professional welding is required for proper installation.
