ENHANCED STABILITY GASKET AND COUPLING

A coupling for joining pipe elements has cast segments attached end to end surrounding a central space. The segments define a channel that receives a gasket. Side surfaces within the channel have angularly oriented capture surfaces which are engaged by bulbous rims on the gasket which prevent the ga...

Beschreibung
Zusammenfassung:	A coupling for joining pipe elements has cast segments attached end to end surrounding a central space. The segments define a channel that receives a gasket. Side surfaces within the channel have angularly oriented capture surfaces which are engaged by bulbous rims on the gasket which prevent the gasket from being dislodged from the channel when at least one pipe element is inserted into the central space. Side surfaces may also have support surfaces between the capture surfaces. The gasket supports the segments in a preassembled state wherein the segments are in spaced relation sufficient to permit insertion of one or more pipe elements while the segments are attached end to end.
