When asked about the weakest link in the 996/997 cooling system, many will quicky chime "water pump!" or "coolant reservoir!". In reality, it's this little connector. The Porsche engineers put this little plastic doo-dad to connect two hoses. Unfortunately, as the cars age, the plastic bemes brittle and they break with only the slightest touch.
Replace it with another factory plastic piece, or upgrade to our new and improved aluminum version.
