The thermostat housing or water outlet is a coolant passage that not only protects and seals the thermostat, but also allows coolant to flow back to the radiator when the thermostat is open. Thermostat housings may suffer from corrosion or other damage over time that can prevent them from maintaining a complete seal - this could lead to leaks around the housing or radiator hose. Coolant leaks can quickly lead to engine overheating and damage, so if you suspect that your water outlet or thermostat housing may be leaking, they should be inspected and repaired as soon as possible. In some cases this repair may be as simple as replacing a gasket, but if the housing has been damaged or if the sealing surface is pitted or corroded, it may be a good idea to replace the entire housing assembly or outlet. If you plan to replace your thermostat, make sure to always check the condition of your water outlet or thermostat housing before reassembly, and replace your thermostat housing gasket with a new one to ensure a leak-free repair.

I carefully examined that and decided that it was probably sealed since I could see that there was rubber all the way around between the parts and that the gasket at that point was probably slightly off-center or out of the track.
