ABSTRACT:
A telescoping seal uses a split resilient gasket surrounding the slide pipe at the bottom of the tank. The gasket has a slanting outer side, mating with a slanting seat in a lower flange which is attached to the bottom of the tank. An upper flange compresses the gasket downward into the seat, causing the gasket to be compressed inward around the slide pipe, thereby providing a watertight seal which still permits the vertical sliding motion of the slide pipe.
