PCV connection Adapters

Does anyone know what type of connector is on the PVC male, and the female on the intake manifold? Is it specific to MB/ M156?

Im asking because im doing a diy catch can. I ordered and have the catch can, all the hoses and attachments (10 AN) EXCEPT the adapters.

I have attempted to track some down from multiple vendors, and they are out of stock from the manufacturer. Have got estimates from 1- 4 months from various different vendors.. I don’t want to wait that long, so I’m trying to find a solution. If the connection is not common, then I’ll have to make/have them made. Here is a picture of said adapters: I really only need the 2 pieces on the right with the flange for the IM.

I'm going to build a custom catch can setup with the Improved Racing universal. I've been looking at PCV and intake adapters from various companies (e.g., Precision Works) but wanted to gauge the room for a consensus on which fittings are the best quality. The video above links to the Precision Works set, but is there a better option? Thanks!
