Stainless Bros 604-00100-7000 M18x1.5 O2 Sensor Bung Coped Type for 1.75-2.50 Inch Tubing

The Stainless Bros 604-00100-7000 is a precision-engineered O2 sensor bung designed for adding oxygen sensors to factory or custom fabricated stainless steel exhaust systems. This coped-type weld bung is CNC machined from high-quality SS304 stainless steel, providing exceptional durability and corrosion resistance in harsh exhaust environments.

Key Features:

• CNC machined from premium SS304 stainless steel for superior corrosion and heat resistance
• M18x1.5 thread pitch compatible with most standard narrowband and wideband oxygen sensors
• Pre-coped design specifically fits exhaust tubing from 1.75 to 2.50 inches in diameter
• Coped profile allows for precise fitment and easy welding to curved exhaust pipes
• Ideal for custom exhaust fabrication and performance monitoring applications

This weld-in bung provides a secure mounting point for oxygen sensors, ensuring accurate exhaust gas readings for proper engine management and air-fuel ratio monitoring. The pre-coped design simplifies installation by conforming to the curvature of round exhaust tubing, making it perfect for both professional fabricators and DIY enthusiasts working on automotive, motorcycle, or powersports exhaust systems.
