I am not sure what size your probes are but here's what I do:

I use pvc crosses to hold the lines for dP xmitter and for the temp probes. The liquid passes stright through to wb. To hold the temp probes I use compression fittings. I rig my temp probes up by putting a little piece of vinyl tubing that is the same ID as the OD of the probe. Then I tighten that down into the compression fitting using that tubing as a kind of washer. Works fine for me.
