Loc line coupling for RSR 350

[Paleozoic_reefer]

Can someone point me in the right direction on what I need to purchase to connect a split loc line to a RSR 350 display return? I need to find (or 3D/Resin print) a coupling that will work. My LFS didn’t know and said RSR piping is proprietary (?!)…
Thanks!

It’s metric. Google up @Vivid Creative Aquatics. They have the adaptor as well as the rfg random flow generators which are amazing
