will this work on a 3/4in loc line ball valve?

This model is for 1/4 inch hose they make one for 3/4 inch hose. The valve will have an NPT and a snap on the other the 3/4 inch hose pliers is at https://www.amazon.com/Loc-Line-78004-Hose-Assembly-Pliers/dp/B0025PUF1M/ref=sr_1_17?gclid=Cj0KCQiA-qGNBhD3ARIsAO_o7ykQ0P-6cnGP7cuE91XITp1lLlKzlDx1E2H3kmR7fVatx8HcyleMR74aAu9tEALw_wcB&hvadid=409959260398&hvdev=c&hvlocphy=9027743&hvnetw=g&hvqmt=b&hvrand=16941392670538074310&hvtargid=kwd-327306091120&hydadcr=24658_11410763&keywords=3%2F4+inch+loc+line&qid=1638453487&sr=8-17

The ball is in ball end and socket is in socket, but I cant get them to snap lock. It looks like the plyer fingers splay out with pressure. Why?

I think you may have them reversed. Last time I used this, it seemed to work when I put the ball end in the socket labeled side of the pliers and vice versa. try that. Good luck '

Can someone measure between the "spokes" on these? Im trying to find something that will work with plastic doll armature that looks like this tubing.

These pliers are intended specifically for Loc-Line's 1/2" coolant hose system, so we cannot confirm or deny that they will work in your application. That being said, the width of the opening on the working end, varies from .60" to .75". I believe that is the dimension you're looking for.

How do I use these to disconnect pieces??

Insert the tool in between two connecting pieces and apply pressure to the tool handle. Further videos can be found online
