A connector for interengaging the exhaust header components of an internal combustion engine that are subjected to movement and vibration to a turbine compressor and/or tail pipe components that are constrained and relatively unmoving wherein inner and outer sleeves of generally telescoping type are separately joined to said moving and constrained components by angular misalignment compensating ball socket joints held in assembled relation with said components by mating flanges. Said inner and outer sleeves further cooperatively provide a close interfitting engagement between a smooth cylindrical surface on one sleeve and a plurality of spaced circumferential ribs on the other sleeve to provide spaced apart pressure sealing zones whereby the pressure of any escaping exhaust gases are reduced by stepped gradients. A pressure collar disposed exteriorally of the interfitted sleeves and in communication with at least one of said zones is itself subjected to superatmospheric pressure to minimize loss of exhaust gases past said seal zones and pressure collar.
