Danco 36450B Faucet Washer Assortment, Rubber, For: 13/16 in, 15/16 in Aerators

This Danco aerator washer fits between the end of the spout and the aerator. It provides a positive seal at the faucet spout and helps prevents faucet drips. Replacing worn out washers will stop dripping water and will save water and money. Aerators limit water flow through the faucet allowing water use to be reduced compared to the same time flow without an aerator. In the case of hot water, because less water is used, less heat energy is used.
