Weld-on sleeve with sealing ring and screw plug for the exhaust on your moped, moped or small motorcycle, as well as for Piaggio Vespa scooters or scooters and any other combustion engine, to measure the air oxygen content.
The welding plug can be welded on using any common welding process.
Note: We recommend leaving the screw fitted during the fusion process and not removing it during the cooling process, as the thread could otherwise become distorted.
