That part is called a sewer vent pipe cover gasket.
They only last 2 to 3 years.
A screen is added over the pipe, then the gasket is slipped over the screen and pipe.
Then the gap between the gasket and pipe is filled with Vulkem sealer.
That gasket costs very little.
All of them should be replaced at the same time.
