you might use a 1/32" low mass external union from VICI, that is reusable (with new ferrules)
Fix it a bit on the steel capillary to avoid stress during autosampler moves.
What might also work a glass press fit (as on the PoraPlot column inside the Gasbench).
However, I prefer to build my own 25$ needles from standard swagelock parts. There is a principle instruction on the isogeochem website or caontact me off list.

We do have some Press-Tight fittings (Restek 20446) and some epoxy... Am I a fool to consider it? If I do try, are there issues to consider besides leaks and dead volume in the connection?
