Converting Xantia strut tops

[white exec]

An engineer will have to take the Activa unions, and plug the threaded hole in them (which previously took a 10mm pipe), and re-drill and tap a new thread for your 3.5mm screw-in unions. The drawing above should help.

Either this, or couldn't same engineer scratch-fabricate a dedicated screw in plug that can be loctited into the strut top, with the 3.5mm fitting drilled into it? Just thinking, Activa unions surely aren't required as a starting point & might be easier to start with a simple piece of round bar machined to fit?

You could be right. Activa union without its 10mm bell-ended pipe probably wouldn't seal anyway, without thread sealant.

That was my thoughts too, it'd require Loctite/epoxy or similar to seal the threads anyhow so it'd probably be quicker/easier to make an adaptor from scratch (unless one used the idea of brazing to a section of Activa 10mm pipe of course)
