Product review (5 stars): Whirlpool 3378134 Dispenser Cap
I got the Whirlpool 3378134 Dispenser Cap. My boyfriend broke the cap so I ended up ordering one. It fit perfectly and have not had a problem with it. Twist it on and off easy as that. Do recommend this product to anyone that needs this size of Whirlpool 3378134 Dispenser Cap. :)
