The vibration and dust isolation system for use in isolating first and second spaced elements (20, 22) which together form at least a part of the structure (14) to be sealed. A resilient strip (30) is interposed between the elements and a fastener (26) secures the elements in sandwiching relation to the strip. The improved strip is generally planar with a considerable majority (40) of the strip having a first thickness less than the spacing between the first and second element, an edge (42, 56) having a second thickness somewhat greater than the spacing, and a load bearing portion (38) having a thickness somewhat greater than the spacing and comprising a considerable minority of the total surface of the strip. The load bearing portion is the predominant part of the strip contacting both elements.
