I don't have a photo. (edit: Not true, see attachment.)
My Bowden extruder had 6mm threads for a tube fitting under the extruder, I believe that this is typical.
My hotend had 1/8" NPT threads for the tube adapter fitting on it.
I fit them together by purchasing a 1/8" NPT to 1/8" "nipple" fitting. Then I ran the nipple fitting though a 6mmx1mm thread die. The end result is a solid brass fitting that screws into the Bowden extruder and into the top of the E3D style heatsink. I used a 6mm nut as a spacer, but could have just cut a bit off of the top of the nipple fitting. I also drilled a small hole to add a grub screw to the fitting before I added the spacer nut, but I don't think that it was really necessary in the end.
