<p>A coupling (10) for connecting a vehicle exhaust pipe (14) to an exhaust conduit for removing vehicle exhaust gases has a cylindrical housing (18) with an inlet (26) at the front end and an outlet (60) at the rear end, the rear end being connectible to an exhaust. A bristle assembly is mounted within the housing (18) adjacent the front end. The bristle assembly includes an annular retainer (48, 50, 52) and a multitude of resilient bristles (40) extending radially inwardly from the retainer (48, 50, 52) towards the longitudinal axis of the housing (18) and therminating at a position spaced from the longitudinal axis to provide central aperture. The bristles (40) project radially inwardly from the retainer (48, 50, 52) by a distance in the range from about 4:1 to about 8:1 longer than the radial thickness of the retainer (48, 50, 52) to enable the front end of the housing (18) to be pushed over a vehicle exhaust tail pipe (14) to cause the tail pipe (14) to bend the bristles (40) rearwardly into engagement with the tail pipe (14) to produce an effective gas seal between the front end of the coupling (10) and the tail pipe (14).</p> |
