Product review (4 stars): easy repair. My washer is from the early 1990s ...
works on old whirlpool washer. Only problem was does NOT include the cap seal o-ring  pictured. Thought it was a missing item but the description does not say it includes the seal as pictured. Ordered new cap and seal separately for $5.75. Overall, easy repair. My washer is from the early 1990s and it worked just fine.
