har har 8 sided, yes i know i cocked up thats why i put the annotation in the video. if its going to work well you need to use a 6 sided spanner or knock the next size down over it, if you have to knock a spanner over it use a 12 point spanner and plenty of wd40. the closer to paralell to the nipple you can get the better.
i got lucky with this one as it wasn't too seized, if you can get most of the shit off with a wire brush you might be on to a winner
