Description

Walker Products Oxygen Sensor Bung Plugs are OE Replacement service components designed to seal unused oxygen sensor ports in automotive exhaust systems. Whether used during exhaust system modifications, sensor relocation, or test procedures, these plugs maintain system integrity by preventing exhaust leaks, backpressure issues, and contamination. Each plug is precisely machined to match standard O2 sensor thread pitch and size, ensuring a secure, vibration-resistant seal in upstream or downstream bung positions. Constructed from corrosion-resistant, high-temperature steel alloys, Walker bung plugs are built to endure extreme exhaust conditions and repeated thermal cycling. Designed for easy installation and removal with common hand tools, these plugs offer a reusable solution for tuning shops, emissions service centers, or DIY installers. Walker Oxygen Sensor Bung Plugs are trusted by technicians to support clean, professional exhaust repairs and system customizations without compromising performance or durability.
