I am looking for what has worked in the past.
Andrew,

I have used the Swagelok QC-6 connectors with the PVR-BASC unit back in 1998, it worked fine and was needed for the high-er gas flow needed for SCR.

In addition, I have used the QC-4 connectors with the MK-15 unit since 2000, it also worked well for the low-er gas flow needed to top off loop volume.

Both are not exactly "zero-water-intrusion" which means a few dropplets will be introduced into the system when you plug/unplug the connectors u/w (i.e. gas switching from bottom mix to deco mix on the PVR, for example), but this amount is minimal and not critical unless you have a small orifice (i.e. KISS) for the gas to flow thru. Then the orifice might get clogged after a prolonged period of use.

If you are planning to use the connector for much higher flow of OC-bail-out, then I suggest the QC-6 since the rated flow is higher in exchange for lower pressure rating.

Personally, I am incorporating the APV GCS connector system into my unit over the holiday since they are much lighter weight than the QC-series. And cheaper as well, not mentioning easier to work with since they use standard scuba rubber hoses.
