Abstract
A sealing member is disclosed having an outer surface that supports segments of a pipe coupling for joining pipe elements in end to end relation. The segments are supported in spaced relation to permit the pipe elements to be inserted into the coupling without disassembly. The sealing member is a flexible ring that has conical lips around its inner circumference to engage and guide the pipe elements into the coupling. A tongue extends radially inwardly between the lips, the tongue having conical shoulders which engage and guide the pipe ends. The tongue locates the coupling segments relatively to the pipe elements.
