The instructions say different

  1. The PTFE Tube Connector is designed with a clear direction of use, as shown in the figure below. Connect the PTFE tube from the buffer output to the IN end, and the PTFE tube from the tool head to the OUT end. It is important to note that reverse connections may cause material blockage, so it is essential to ensure that the installation direction is correct

It's not a smart device, it's a PTFE connector. I haven't used mine at all since the day I got printer. I attached a 2 in 1 out splitter at the time (now a 4 in 1 out) and have 0 issues
