OK,
@day_trippr and
@doug293cz , here's what I ended up doing after your responses and ideas.
I realized with my setup that it would be difficult to get a camlock on and off a fixed connection. The place for the line to go through the front facade of the sink has to be all the way to the left, to clear the sink bowl, and in that location, I wouldn't be able to close the camlock wings.
So I checked my parts box and found I had a rubber grommet that is exactly the right size for that 1/2" ID silicone tubing. I drilled a hole with a step-bit, added the grommet, then put a male camlock connector on the silicone tubing. Fed it through and sent it down the PVC pipe coming up from the trap, and connected the other side to the steam slayer.
It works. I have the double-elbow on there to raise the height so as to have enough elevation drop to avoid any pooling of the water. As said by either
@Bobby_M or
@BrunDog if the line terminates in water or fills with water, it won't work. The other advantage is that last time I used this, I had a boilup of hops, and that went out the port and into the water bucket. This should prevent that, at least to some extent.
I ran the system this afternoon with a few gallons of boiling water. Here's a short you-tube video showing it working and taking the lid off showing the steam.
Also some pics showing how it works. I wanted something that wouldn't require me to monitor a bucket full of water, but if I add a short piece of silicone tubing with male camlock to what comes off the steam slayer, I can drop that tubing into a bucket to reuse for cleaning.
