Abstract:
An engine exhaust system comprises duct pieces (201, 202) and a sealing joint (30) for interconnecting their adjoining ends. The sealing joint (30) comprises a one-piece tubular body (31) including a first axial end portion (331), a second axial end portion (332), and a bridge portion (34) extending therebetween. The first end portion (331) is at least partially positioned within a female recess (231) of the first duct piece (201) and the second end portion (332) is at least partially positioned within a female recess (232) of the second duct piece (202). Depending upon the thermal expansion-contraction conditions in the exhaust system, the bridge portion (34) can extend across a gap (24) and/or it can be positioned partially within female recesses (231) and (232).
