A pivot joint comprises a pivot pin mounted to a first member and a second member with a housing defining a bore receiving the pivot pin, thus forming a pivot axis for pivotal movement of one member relative to the other. A resilient toroidal gasket is provided at either end of the housing in the bore at axially spaced positions of the pivot pin, and a circumferential recess receives each gasket in fixed axial location along the pivot pin. The gasket spans radially of the pivot pin from a base of the recess and across a circumferential gap formed between an inner surface of the bore and an outer surface of the pin where lubricant is suitably received. Thus the gaskets form a sealed interior of the bore closed at either end by the respective gasket so as to maintain the lubricant therein and contaminants out.
