Abstract: A housing has an opening therein, a rod extends within the opening in the housing, and an annular seal arrangement is provided around the rod within the opening for effecting a fluid seal between the housing and the rod with respect to a fluid pressure which is present at a location along the rod on one axial side of the seal arrangement. The seal arrangement includes an annular washer part which is provided closely around the rod and an annular sleeve part axially adjacent the annular washer part, the annular sleeve part having an inside dimension which is less than an outside dimension of the washer part and which is substantially greater than an inside dimension of the washer part and an outside dimension of the rod. The washer part is located on a side of the sleeve part axially remote from the location at which the fluid pressure is present.
