ABSTRACT:
The exhaust tube gasket comprises two elastically squeezable steel rings (20, 22; 120, 122) received on an annular, malleable steel sheet (10; 110). One of the rings (20; 120) closely surrounds the tube passage, while the other, outer ring (22; 122) follows the contour of the joining flanges of the exhaust tube. The inner and outer rims (28, 30; 128, 130) of the steel sheet are folded to extend over the two rings (20, 22; 120, 122), leaving an uncovered space (32) between them. The two rings are preferably V-shaped in cross-section, and they may be joined to each other as an integral plate (40). The outer ring (24; 124) may be absent.
