$9.99

$9.99

This Stainless Bros thread adapter allows the installation of an M12x1.25 oxygen sensor into a standard M18x1.5 exhaust bung. This reducer is essential for custom exhaust fabrication when utilizing specialized wideband sensors or motorcycle-spec sensors that use the smaller M12 thread pitch. Precision-machined from high-grade stainless steel, this adapter ensures a leak-free seal and maintains thread integrity even through extreme heat cycles.

  • Material: 304 Stainless Steel for maximum corrosion resistance and durability.
  • Outer Thread: M18x1.5mm (Standard automotive O2 bung size).
  • Inner Thread: M12x1.25mm.
  • Design: Integrated hex head allows for secure tightening and easy removal with standard wrenches.
  • Application: Suitable for custom headers, downpipes, and tuning equipment setups.
