Clamp On Exhaust Oxygen Sensor Bung
O2 Oxygen Sensor Title:
oxygen sensor plugs m18x1.5 o2 sensor bung stainless steel for Car
Oxygen Sensor Plugs Introduction:
Plug is a matching threaded seal that prevents exhaust gas leakage when the sensor is not installed.
Core functions:
Extended monitoring points: Provide oxygen sensor installation interfaces for modified vehicles or non original exhaust systems to achieve precise control of air-fuel ratio;
Sealing protection: Blocking can isolate high-temperature exhaust gas and moisture, protect threads, and extend the life of the base;
Compatible with: Standardized thread (M18 × 1.5 mainstream) compatible with 99% oxygen sensor models;
Material:SUS304、SUS312、 Titanium alloy;
Base type:
Standard Type,Saddle Type,Finned Style,45 Degree Style,Lipped Type,Notched Style,Hex Bolt Plug Cap,Hex Socket Plug Cap,Oxygen Sensor Bung+ Catalytic Converter,etc.
Saddle Type: The curved bottom conforms to the curved surface of the exhaust pipe, with high welding strength;
Finned Style: External heat dissipation fins accelerate cooling and protect sensor wiring harnesses;

 | SB-SS-R02 | Oxygen Sensor Bung + Catalytic Converter | M18*1.5 |
Application:
Newly added monitoring points for modified cars (second oxygen sensor installed on turbocharged models), emergency maintenance on race tracks, and adaptation to hydrogen energy vehicles.
Sensor and blockage installation
Thread processing
Use M18 × 1.5 tap to clean the carbon deposits inside the base threads;
Apply high-temperature anti sticking paste evenly on the sensor threads.
Tightening specifications
Final debugging and verification
