What is the thread size on the 5/8" compression side of the adapter

the compression side of the fitting is sized for 5/8" tubing which is different from piping sizes, the compression parts under the nut fit around the tubing and when it is tightened the proper amount they lock together and give you a pressure tight seal, if they are assembled correctly and the tubing is inserted fulling into the fitting.

Is this fitting bore-thru to allow a piece of 1/4" tubing to pass through or is there a shoulder/stop to keep it from passing through?

The fitting is not bore-thru there is a shoulder/stop to keep it from passing through. If you need it to pass thru you would need FH4BZ. http://www.amazon.com/Parker-FH4BZ-SS-CPI-Thermocouple-Connector/dp/B00OZCNLMI/ref=sr_1_6?ie=UTF8&qid=1447687808&sr=8-6&keywords=4-4+fh4bz-ss

Is this fitting bore-thru to allow a piece of 3/8" tubing to pass through or is there a shoulder/stop to keep it from passing through?

It is shouldered & stops the tubing.

Will the 3/8 tube side thread allow A standard compression fitting braided hose work!

not enough information. one end of the FBZ fitting is ordinary npt threads, the other is for a compression tube connection. So if your braided hose has a straight 3/8 tube on the end, it should fit into the nut and ferule and then compress to a tight secure connection. Braided hose or rubber hose won't matter.

For 1/8" tubing. Not a 1/8" hole through the whole fitting.

Know that the 1/8" tube size hole does not go completely through the fitting. I purchased this for holding a thermocouple and had to drill out the 3/32" through hole for my 1/8" probe. Otherwise it is a nicely machined part and worked well, once drilled out.
