Product review (1 stars): Unit continually leaked after installing in a Kenmore fridge. ...
Unit continually leaked after installing in a Kenmore fridge.  After a hour of trying different things, I took off the o-rings on both units.  The new ones were smaller in thickness.  I then used the old o-rings on the new filter and there is no leak.  Bottom line....beware of the o-Rings on these replacement filters.
