Its a 'desoldering pump', guys. I have two, and the blue ones with the yellow plunger work the best, even over the metal-casing one I have. Its tagged as a 'Soldapullt SS750' for anyone looking.

The white plastic tips are replacable and are relatively heat resistant, and are held in place with a simple rubber o-ring. Very easy to clean too: slight twist to open, bang over a trash bin, mebbe pick a bit at any caked-on pieces on the plunger and poke any out of the tip, then re-assemble. Can do it in under a minute.

I never use braid/wick any more. Keeps the heat at the board more than a pump.
