ABSTRACT:
A boot seal in the form of a bellows for a shock absorber in the form of a liquid spring mounted in a sleeve having a sleeve flanged secured to a deck by bolts, the boot seal including a collapsible central bellows portion, an upper cylindrical boot portion attached to the liquid spring casing by means of a hose clamp, a lower annular resilient boot flange extending substantially perpendicularly to the longitudinal axis of the boot and having a plurality of first scalloped cutouts in its outer periphery, an annular trim ring overlying the annular boot flange and having second scalloped cutouts in its outer periphery overlying the first scalloped cutouts of the boot flange, retention and spacer washers having lower washer portions extending through the aligned first and second scalloped cutouts and having upper washer flange portions bearing on the trim ring, the lower washer portions being of a length which is less than the combined thickness of the trim ring and the annular boot flange so that when the bolts pass through the retention and spacer washers and are tightened into the deck the lower washer portions will bear on the sleeve flange to maintain a rigid connection between the sleeve flange and the deck and the annular boot flange will be compressed the correct amount to provide a good seal.
