Not sure where to ask about this, since its a bit of a mixture of things (heh).

What I want to do is have my autodoser dump fertilizers directly into the filter output line.
So that means I need a tube thing that has a 16mm "main" line with a 4mm sideline.
Anyone have an idea what that might be called, or if that's even a thing?

I've found a few similar injector line T-split things, but the diameter is never right;

Anyone know where I could possibly find a 4mm - 16mm/16mm one?
I've been scouring ebay and the likes for ages, can't find anything that fits.

You may be able to get the basic 16mm barbed fitting and drill a small hole into it and glue a 4mm nipple onto it making sure the 4mm piece will fit snug in the first place after you drill a hole.

I have never seen one. I would use a standard 3x16mm one and then get a reducer down to 4mm and join it with tubing.

Ive tried looking for a straight union barb reducer piece that goes from 16mm to 4mm,
but it seems that step is a bit out of range since I can't seem to find any of those. :')
