Product review (5 stars): A substitute part, but it works
61001884 is the part number in the official parts list for my Maytag MTB2446AE fridge.  Original part has threaded fittings for both inflow and outflow.  Part supplied has compression fitting instead on outflow.  So far, there is a slow leak.  Not sure if a 'redo' is an option.  I find myself unable to detach the tube, at least with the part in situ.  If this continues I will remove the part and try to detach/reattach the tube.  Hopefully this will work.

Update: Did manage to remove part and reattach hose.  So far it's holding after 30 minutes and at least one ice drop.  Rating upgraded to 3 stars.

Update2: Going strong after four hours.  This appears to be a satisfactory part.
