The product is made of stainless steel.

By using a groove in the socket design, you can easily weld the socket into the pipe. The assembly consists of drilling a 23mm diameter hole in the place where we plan to place the probe. Then we install a new socket in the hole, which thanks to the rolling will rest on the pipe wall. Then we weld the place of contact of the socket with the pipe. Thanks to the use of stainless steel, we are sure that our new socket will never corrode, and we will not have problems in future unscrewing the probe from it. The socket is universal, fits almost all lambda probes. It has a M18x1,5 thread
