Expert Insight:
The 1-021JKABNF is the most common fix for a faucet that drips from the spout even when the handle is turned completely off. Because Chicago Faucets' Quaturn system closes with the water pressure, this washer is pressed firmly against the brass seat to create the seal. Pro Tip: If you replace this washer and the faucet still drips, check the internal 1-027JKABNF Monel Seat for pitting or scratches. A rough seat will chew through a new rubber washer in weeks. For the best results, always use the genuine "Chicago Faucets" branded washer; generic hardware store versions often lack the specific durometer (hardness) required for a long-lasting seal.
