A 180 mm swab with an 18 mm foam head — for cleaning wide channels and connector shells without a wipe.

Construction

The largest head in the range, on a shaft stiff enough to reach into a channel without bowing. Open-cell foam holds solvent at the tip rather than letting it run down the handle.

Where it is used

  • Connector shells and wide ports
  • Cooling channels and slots
  • Applying solvent to a defined strip

Handling notes

Use one swab per pass. Re-dipping a used head contaminates the solvent bottle; decant a small volume first.
