various orientations while still creating a good seal and vibrationally decoupling the members 0036 fig7 illustrates a sixth preferred embodiment of a gasket 510 according to this invention elements in this embodiment that are similar to elements in the previous embodiments will be similarly designated but with 500 series numbers this embodiment is similar to the embodiment of fig6 but with a different sealing and retaining arrangement for the first and second sealing portions only the second sealing portion 514 illustrated but with a similar elastic arm 516 the flange 562 of the second member 520 includes a retaining protrusion 566 extending therefrom the elastic portion 528 surrounds the flange 530 but preferably does not include sealing ribs instead the elastic portion 528 catches on and abuts against the retaining protrusion 566 to create a seal the flange 530 still creates the sealing and retaining force for the second sealing portion 514 the retaining protrusion may be cast molded or formed in some other preferred way on the flange 562 0037 fig8 illustrates a seventh preferred embodiment of a gasket 610 according to this invention elements in this embodiment that are similar to elements in the previous embodiments will be similarly designated but with 600 series numbers a second sealing portion 614 is similar to the second sealing portion in the fifth embodiment of the present invention with a generally u shaped flange 630 creating a sealing and retaining force for sealing ribs 632 abutting a flange 662 of a second member 620 the first sealing portion 612 is now shaped similar to an o ring and fits into a recess 668 with an interference fit between the two in order to create a sealing and retaining force between them.
