<p>Various embodiments of the present invention provide improved coupling devices for joining pipe ends that have improved sealing performance and manufacturability over known pipe coupling devices. One of the improvements provided by embodiments of the present invention is a unique design of the gasket (40, 70, 160). Various embodiments of the gasket (40, 70, 160) include an innovative pipe interface profile (46A, 46B, 80A, 80B, 190, 172) that improves the manufacturability of the gasket (40, 70, 160) itself and its sealing performance.</p> |
