The Frigidaire 218710300 Filter Wrench helps remove the filter cup on Frigidaire and Kenmore refrigerators that use either the WF1CB
PureSource or WFCB
PureSourcePlus refrigerator water filter.
The 218710300 Wrench is also known as P_N_218710300.
The wrench should never be used to tighten the filter cup. The wrench should be used only for loosening the filter cup.
If you apply a little vegetable oil to the Frigidaire O-ring
and hand-tighten the filter cup, you probably won't need to use the wrench next time.
