599993 A coupling 10 comprising a housing 12 having a first lateral side 100 for receiving a first pipe segment 2, a second lateral side 102 for receiving a second pipe segment 4, the second lateral side 102 being spaced from the first lateral side 100 to define a medial axis AA of the housing 12, and an inner surface 22 defining a cavity. A gasket 40 is disposed in the housing cavity for forming a seal about a pipe joint. The gasket 40 includes a first lateral side, a second lateral side spaced from the first lateral side, an exterior surface and an inner surface, with the exterior and inner surfaces extending between the first and second lateral surfaces. The gasket is disposed in the housing 12 such that the exterior and inner surfaces are bisected by the medial axis AA of the housing 12. The inner surface of the gasket defines a central leg extending along the medial axis, and further defines a first sealing lip and a second sealing lip. In an assembled configuration, the housing 12 engages the gasket so as to fold the gasket such that at least one of the first and second lateral sides of the gasket are directed laterally against the sidewall portion of the inner surface of the housing. The coupling provides a better seal. |
