Ribbed pipe clamp with sealing sleeve

摘要

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.
