4 Pcs 141025 O-Ring Kits, Replacement Parts for Pull-Down Faucets

This should be put in and taken out with a toothpick without damaging the 0-ring. The o-ring and screen can be cleaned many times. You rinse the o-ring and use a toothbrush (clean, just for that purpose) and a clothes pin to keep the hose from dropping back down while you work on the faucet head. You can still use the water hose to since away debrisas you scrub. Use it on low. Definitely buy this and the o-ring is not forver , but not a one time use.
