Intex Plunger Valve Air Inlet?

[Grootsquad]

I have this little valve thing on both of my Plunger Valves for my Intex Pool, one of them is leaking.

Anyone have an idea of what it is and how I stop it from doing so?

Welcome to TFP! All I could find was something from Amazon HERE. Perhaps part of the air intake portion, but yours doesn't have the cap like the one on Amazon so I'm not sure. For the leak, it may just be a simple O-ring that needs to be replaced.
