This custom machined screen (11mm diameter) is for keeping secure the balls inside the Tempest Cap.
There is about 2.5mm of space between the top of the Bowl and the Ball Retaining screen inside the Cap.
BR screen doesn't choke the airflow, as the Tempest Heater design favors Restricted Direct Lung or Mouth To Lung draws.
It's common sense that users should regularly check if this screen is still screwed to the Cap threads, particularly with heavy use, drops, shock, thermal expansion...
Threads have a slight angle, so it is normal that one side of the RB screen looks a bit bent, when correctly installed.
Users who will want to often change ball materials inside the Tempest Cap, should order some spares BR screens.
The online Tempest instructions suggest a ball cleaning maintenance every 300 bowls, so better to get some spare BR screen, just in case.
Using a small flat head screwdriver, the Reload Debowler rod, or the Leather case multi-tool to screw the BR screen until the end of the threads.
Be gentle, do not insist if it feels tight and take time to correctly catch the threading, without over-tightening at the end.
If the BR screen doesn't stop at the end of the threads, there are too many balls inside the Cap.
Bowl's screens can't be used as a substitute, they are 10mm diameter, in SS mesh.
