Abstract

A handle and housing assembly has a graspable handle turnable about a principal axis relative to a housing, structure extending from the handle along the principal axis through an opening defined by the housing, and a seal that turns with the handle and defines a thin annular skirt of resilient material extending about the principal axis and pressed substantially flatly into engagement with an annular portion of the housing extending substantially concentrically about the opening. In some embodiments, the structure includes a shaft that extends from the handle through a spacer that is encircled by the skirted seal; in some embodiments, an O-ring is interposed between the handle and the spacer; and, in some embodiments, a rear part of the spacer extends into the housing opening to facilitate smooth turning of the handle and the spacer about the principal axis.
