Its is a float valve just like the one phito pointed out. You can buy them online at J&L Aquatics. Mine is a coralife, but I think J&L carries Kent Marine.

awsome thanks.its the last piece i need for my water top up.the cheap 4 dollar ones on ebay from china look umm...china cheap lol

When ordering keep in mind that you only need the float valve. Sometimes they come in kits with a bunch of stuff you don't need.
