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

Would work for the right product

I got these to use on heavy duty joints, not for the coolant hose system. I think they would work for what they are designed for but the pieces I had required a heavy duty solution. This just couldn't keep up but that's fine
