Hi there. Can anyone tell me the name of the cracked nut in the photo. I know it's some sort of bleed valve but can't find them on the Internet. Need to get a new one.

Better to replace it with automatic air vent.

Yes, and don't forget to put a service valve under it for future maintenance while you are at it.
