Haltech's O2 sensor weld-on bung is CNC-machined from high-grade 6061 aluminium alloy for professional exhaust fabrication work. This precision component allows you to permanently install oxygen sensors at optimal locations throughout the exhaust system for accurate air-fuel ratio monitoring. The 6061 alloy offers excellent thermal stability and corrosion resistance in harsh exhaust environments, while its lightweight construction minimises added mass. Designed for clean TIG welding, this bung ensures a secure, leak-free installation critical for reliable wideband sensor readings during tuning and ongoing engine management.
