Tim,
joiner1970 is using a Midi vac, and as such the Festool Y adaptor may not be entirely suitable. Although the Y adaptor is quite long, it's not quite long enough to reach into the vac port:

If you orient it with one leg of the Y into the cut-out/shaped part of the hose dock, you can angle it forward & get it into the port, but it doesn't quite seat properly & there will be a little bit of air leakage around it, but not enough to worry too much about:

If there was some pull on the hoses, it may possibly fall out, but for a static application such as a router table it shouldn't be a big deal.
These pictures were taken with my Mini, though the Midi is exactly the same shape on top.
Joiner,
You say you have some spare hose - is it 27mm or 36mm?
If it's 27, then there's an easy, off-the-shelf solution. The 27mm hose is a nice, tight fit inside 30mm solvent weld waste pipe (which has an OD of 36mm):

So with a short length of that fitted to all the ends, you can use a solvent-weld Y or T fitting. Because the solvent weld pipes & fittings are quite tight, you can get away without using any solvent, making it easy to set up & break down.
Edit: It's just occurred to me that if you're using 36mm hose, you may well be able to do the same with 40mm SW waste pipe (which an ID of 38.6mm). Unfortunately I don't have 36mm hose so I can't check the OD of that.
