Product review (5 stars): There are some good videos online about how to change this out
Bought this to replace the seal on my Sears HE3 washer. Fit perfectly!  Have not had any leaks from the washer now since I installed a few months ago.  There are some good videos online about how to change this out.  I am sure I easily saved over $100 dollars by changing this out myself. You do need some rudimentary skills to change these out but it isn't rocket science.
