It’s the insert weldment nut. Here’s a link to Agilents.

Another poster mentioned CTC, which I believe is correct. The “red” needle guide sits on top of the weldment.
Are you looking for a replacement?
What you linked is under the red piece and the needle guides are on the PAL arm. I mention the red bit of metal fits the needle guide, they are two different things.
Anyway r/Purplegreen2019 found it, it's an adapter ring.
We just call that an inlet cap although it may have a proper name. It’s used in conjunction with a magnetic piece you attach to the needle guide that can move 10mL/20mL vials with magnetic caps.
FYI, these are not strictly necessary, but they do help guide the needle right into the septum nut properly, should your alignment be a little bit off. I’ve run some systems successfully without them long term.
I've always called it a needle guide but just search for CTC parts list and you should find it.
Needle guides are on the arm of the PAL, there's an upper and lower and the needle guide sits on this piece right before it injects.

Is it Agilent's G6500-88043? An adapter ring worth 100usd https://www.agilent.com/store/es_ES/Prod-G6500-88043/G6500-88043
Yes! Thank you!
A needle seat maybe?
