Will this fit the vevor 6 ton press

It should as long as it isn't the pinned style release valve on the jack. May want to measure the release valve first so you get the correct size. I guessed on mine and it was too small (not much but enough something would have to be modified) returned and ordered the larger size (for my press HF 20ton) and it fit perfect. Very well machined and makes the press easier to use.

Will it work on the harbor freight 2 ton shop crane ( engine hoist ) .?

Yes it will, just buy the smaller sized screw hole.

Will this work on the HF 8 Ton Bottle / Press?

Should fit, they all seem the same release valve.
