A pipe coupling has a housing, a mounting portion extending away from a first side of the housing, and a hinge portion extending away from a second side of the housing. The housing is defined by a first axial wall, a second axial wall spaced apart from the first axial wall, and a semi-cylindrical outer surface extending between the first axial wall and the second axial wall. Each of the first axial wall and second axial wall have a semi-annular shape defining a passage radially inward from the first axial wall and second axial wall. The mounting portion has a flange and a hole formed through the flange. The hinge portion includes a tab and a frame. The tab extends partially between the first axial wall and the second axial wall, and the frame also extends partially between the first axial wall and the second axial wall.

Pipe coupling

A pre-assembled pipe coupling includes a gasket, a housing surrounding the gasket, and a fastener. The housing has three segments sequentially coupled to each other to define an insertion boundary. A first segment includes a first mount extending lateral in a first direction from the wall and having a plurality of first lateral walls that define a first aperture, and a second mount extending laterally in a second direction from the wall, the second mount having a plurality of second lateral walls that define a second aperture. A second segment includes a first hook disposed in the first aperture and a first tab defining a first fastener aperture. A third segment includes a second hook disposed in the second aperture and a second tab defining a second fastener aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture.

Pre-assembled pipe coupling with manually manipulatable segments

A pre-assembled pipe coupling includes a gasket, a housing surrounding the gasket, and a fastener. The housing has three segments sequentially coupled to each other to define an insertion boundary. A bridge segment has a first mount extending lateral from the wall and having a plurality of first lateral walls defining a first aperture and a second mount having a plurality of second lateral walls defining a second aperture. A first clamp segment has a first hook disposed in the first aperture. A second clamp segment has a second hook disposed in the second aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture. The fastener has an adjusted length at which the first clamp segment grips the gasket, and the second clamp segment grips the gasket to locate the first sealing lip and the second sealing lip within the insertion boundary.

A coupling arrangement that includes a gasket seal and a housing having a first lateral side for receiving a first pipe segment and a second lateral side for receiving a second pipe segment, the second lateral side being spaced from the first lateral side to define a medial axis of the housing. An inner surface of the housing defines a cavity for engaging and housing a gasket seal disposed about the first and second pipe segments. The gasket seal includes a peripheral surface and inner surface which can include features than engage both the housing and the pipe segments to form a fluid tight pipe joint assembly.
