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 and an inner member having a tapered end designed to frictionally engage the seal and spring wherein the inner member is reciprocally disposed within the outer housing. The inner member is retracted inside the outer housing by a retraction spring; and the tapered end of the inner member is forced beyond the end of the outer housing to engage the seal and spring.
