The Stainless Bros M18x1.5 Step Type O2 Sensor Bung is an essential component for professional exhaust fabrication and custom header builds. This precision-machined bung provides a secure, threaded mounting point for standard oxygen sensors or wideband air-fuel ratio gauges.

Designed with a specific "step" shoulder, this bung simplifies the welding process by allowing the part to self-center within a pre-drilled hole in the exhaust tubing. This feature ensures the bung remains stable and properly aligned while you lay your TIG or MIG beads, preventing it from slipping into the pipe. The M18x1.5 thread pitch is the industry standard for most automotive O2 sensors, making this a versatile choice for forced induction setups, downpipes, and naturally aspirated exhaust systems.

  • Manufacturer Part Number: 604-00100-8000
  • Thread Size: M18 x 1.5
  • Profile: Step Type for self-centering fitment
  • Application: Custom exhaust systems, turbo downpipes, and headers
