218720100 Frigidaire PureSource Water Filter O-Ring

	218720100
	$4.10

The Frigidaire O-Ring 218720100 fits Frigidaire and Kenmore refrigerators that use the PureSource (WF1CB) and PureSourcePlus (WFCB) filters.

The O-ring seals the filter housing to the refrigerator, and prevents water from leaking into your refrigerator compartment. It sometimes gets damaged when the filter housing is unscrewed, especially if it's so tight that you have to use the Frigidaire Filter Wrench to unscrew the housing. The O-ring should be replaced if you can see any nicks, tears, or any other visible damage.
