First Claim
Patent Images
1. A method of coupling a first pipe element and a second pipe element in end-to-end facing relationship comprising:
- aligning a coupling with an end of the first pipe element;
the coupling comprising;
at least one segment, each segment defining a first end and a second end, the first end disposed opposite from the second end, each first end and each second end defining a fastener hole;
at least one fastener, each fastener extending through at least a one of the fastener holes; and
a gasket, each segment positioned annular to the gasket, the gasket comprising;
an annular body; and
a pair of sealing ribs each extending substantially radially inwardly from the annular body and defining a sealing ridge at a radially inward end of each of the pair of sealing ribs, each sealing ridge of the pair of sealing ribs defining a cylindrical sealing surface at an innermost radial extent in an uncompressed state, the cylindrical sealing surfaces defining a coupling void;
inserting the end of the first pipe element into the coupling void;
aligning an end of the second pipe element in end-to-end facing relationship with the end of the first pipe element;
inserting the end of the second pipe element into the coupling void; and
engaging each fastener with the at least one fastener hole of the at least one segment to bring the at least one segment into contact with a first outer surface defined by the first pipe element and a second outer surface defined by the second pipe element.

Abstract
An annular gasket includes an annular body; an annular body; a pair of sealing ribs each extending substantially radially inwardly from the annular body and having an innermost radial extent; and at least one center rib extending substantially radially inwardly from the annular body, the at least one center rib having an innermost radial extent closer to the annular body than the innermost radial extent of each of the pair of sealing ribs.

11. A coupled pipe joint assembly comprising:
-
a first pipe element defining a first end; a second pipe element defining a second end, the first end and the second end positioned together in an end-to-end facing relationship; and a coupling, the coupling comprising; at least one segment, each segment defining a first end and a second end, the first end disposed opposite from the second end, each first end and each second end defining a fastener hole; at least one fastener, each fastener extending through at least a one of the fastener holes; and a gasket, each segment positioned annular to the gasket, the gasket comprising; an annular body; a pair of sealing ribs each extending substantially radially inwardly from the annular body and defining a sealing ridge at a radially inward end of each of the pair of sealing ribs, each sealing ridge of the pair of sealing ribs defining a cylindrical sealing surface at an innermost radial extent in an uncompressed state, the cylindrical sealing surfaces defining a coupling void, the first end of the first pipe element and the second end of the second pipe element disposed within the coupling void; and at least one center rib extending substantially radially inwardly from the annular body, the at least one center rib defining an innermost radial extent closer to the annular body than the innermost radial extent of each of the pair of sealing ribs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
