Vibrant Saddle Style Oxygen Sensor Weld Bung T304 SS (M18 x 1.5 thread) - Retail Pack of 1 pc.

If you're fabricating a custom exhaust system and need to add a port for an oxygen sensor, this saddle-style weld bung from Vibrant is a solid choice. It's designed to make adding that sensor port a cleaner, more straightforward process.

This bung is made from T304 stainless steel, which is well-known for its resistance to corrosion, so it'll hold up well in exhaust environments. The saddle design features a radius that matches the curve of typical tubing, allowing it to sit flush and create a stronger, cleaner weld. The M18 x 1.5 thread size is standard for many modern oxygen sensors.
