Looking For Part; Inline Fertilizer Injection Splitter Piece? Question

    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 thats 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, cant 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.

    Look at rainbird drip systems. Lots of fittings for this application

    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 cant seem to find any of those. :')
