A seal assembly for a vapor generator each wall of which has spaced lower and an upper portions to accommodate relative movement there between. The seal assembly includes a trough containing water and connected to one of the portions of each wall. A dip skirt extends into the trough and divides same into an inner chamber and outer chamber, and a partition extends from the dip skirt, across the space between the wall portions, and to the other wall portion to expose the water in the inner chamber to the boiler pressure and the water in the outer chamber to atmosphere. As a result, relative movement between the wall portions is accommodated by corresponding movement of the dip skirt in the water trough while maintaining an airtight seal.
