Skimmer part?

Can you tell me what the pictures item is in my skimmer? I’ve been having problems vacuuming (pressure loss) and I suspect this maybe the culprit?

It’s hard to say for sure but it looks like it may be a valve cuff. These are used with suction cleaners. It may be something like part number 3238-028.

Sounds feasible, thanks for your expertise!
