In order to facilitate the application of O-ring seals to, for example, a faucet valve stem having a serrated upper end portion and a lead screw having relatively sharp edges which would tend to cut or abrade an O-ring seal there is provided a hand tool having an elongated tube, one end of which presents an expansion member, and the other end of which presents a head member. A plurality of O-ring seals are mounted on the tube in stacked relationship, with each O-ring seal being operatively rolled over a divergent walled portion of the expansion member thereby smoothly and uniformly to expand the O-ring seal, and then being rolled along a plurality of equi-angularly spaced, reiliently deformable prongs for application to the valve stem while the serrated upper end portion and the lead screw of the valve stem are disposed within these prongs. The tool also serves to store the O-ring seals in an orderly and convenient manner prior to use. |
