A simplified tool for removing and inserting a plumbing fixture seal, particularly for use with ball type faucets using a rubber seal engaged by a cylindrical compression spring. The tool comprises an outer housing; an inner member having a tapered end designed to frictionally engage the seal and spring, the member being reciprocally disposed within the outer housing, the inner member being retracted inside the outer housing by a retraction spring; and a mechanism for extending the tapered end of the inner member beyond the end of the outer housing sufficient to engage the seal and spring.
