Abstract: A pipe coupler for use in connecting a pair of automotive exhaust pipe ends each having a circumferential rib. The pipe coupler includes a ribbed band and internal split sealing sleeve along with a tightening mechanism for clamping the band and sleeve over the pipe ends. The sealing sleeve fits within the band and both the sleeve and band have a pair of ribs positioned to fit over the ribs on the pipe ends. The sleeve extends circumferentially from a first end to a second end, and includes a tongue-and-groove sealing configuration located axially inwardly of the ribs at the first and second ends. Each tongue has a particular construction that accommodates larger clamp opening dimensions required to fit the coupler over the pipe ribs during assembly. The sleeve can include inwardly protruding sealing beads that help prevent leakage of exhaust gases from the pipe junction.

Abstract: A pipe clamp that is used over a ball joint formed between a balled end of a first pipe and a flared end of a second pipe. The pipe clamp has a band and a tightening mechanism. The band extends axially from a first edge to a second edge, and extends circumferentially from a first end to a second end. The band has a step formed circumferentially in a body of the band between the first and second edge. The step accommodates a stepped seam that is produced between the balled end and the flared end when they are overlapped with respect to each other. The tightening mechanism draws the first and second ends of the band toward and away from each other in order to respectively tighten and loosen the pipe clamp.

Abstract: A band clamp used to connect tubular bodies such as vehicle exhaust system components. The band clamp has a band extending from a first end to a second end and includes a pair of spaced ribs extending at least part way between the first and second ends. A tightening mechanism is connected to the band and includes two clamp members movable toward and away from each other for tightening and loosening of the band. The band clamp further includes a gasket located on an inner surface of the band between the ribs and extending between the first and second ends. The use of the ribs with the interposed gasket provides a mechanical interlock of the band clamp with the tubular bodies while providing a hermetic seal at the junction between the two bodies.
