Flashforge Finder / Finder Lite Spare Mica Pad – Hotend Insulation Plate

You're seeing heat bleed into the heat-sink side, or your hotend temps are drifting and you can't figure out why. The mica insulation pad is doing its job until it isn't — then it cracks, degrades, and lets heat escape where it shouldn't. This is the correct replacement mica pad plate for the Flashforge Finder (TL4220) or Finder Lite (TL4222). Pop in the new pad, torque it to spec, and your temperature stability comes right back. Small part, big difference
