Pipe clamps are commonly used to join tubular components together; for example, pipes or tubular housings. These clamps can be used in a variety of applications with some clamps specifically designed for specific components or for use in specific applications, and others of a design intended to make them more generally or universally applicable. One such application of pipe clamps is in connecting pipes or other components in automotive exhaust systems. Often, these exhaust system applications require or at least desirably provide a joint between pipe ends that seals against exhaust gas leakage and that has good resistance against axial separation. One type of pipe clamp is a band clamp which is used with telescopically overlapping pipe ends, and another type is a pipe coupler which is used with end-to-end abutting pipe ends. Both types usually include a metal band to be placed and tightened over the pipe ends, and both types can include a sealing sleeve and/or a gasket to be sandwiched between the band and the pipe ends.
