The Berkeley S16800 seal-retainer gasket is a replacement gasket for the seal-retainer location on compatible Berkeley B4ZQKHS pumps. Its 5-1/8-inch inside diameter and 6.94-inch outside diameter provide two useful checks when comparing the removed gasket with the replacement.
The seal-retainer gasket is a different service item from the volute gasket and mechanical shaft seal. Selecting S16800 for the correct location avoids ordering another gasket from the same pump assembly. Use the pump B/M number as well as the gasket dimensions; size alone does not establish fit.
