In case anyone else has invested in a bunch of Kegland disconnects and is tired of using steel pliers to get the caps off, here is a tool that makes it much easier:

Not only does it have non-marring jaws, but it closes to exactly the right width to turn the caps without marring them or squeezing them against the disconnect bodies. When you squeeze the caps against the bodies, it creates a lot more friction.
I wouldn't shell out $32 just to get disconnects open. I already had this thing. There are probably other pliers that will do the same job.
The main problem with the disconnects seems to be getting them open when they're new, but it may be that problems could arise later, so if you have a whole bunch of these disconnects, this could be a good investment.
