Rated 1 out of 5 by from Not Needed I suppose it's going to work OK, but it's not the part that I really needed. I discovered only after I had ordered this that the tank had cracked in the corners and that was causing leaks. A few minutes with a hot glue gun have fixed the tank. Tossing this item in the garbage now - don't need it and not worth the time to return it.

Rated 5 out of 5 by from Exact replacement. The cap has a spring plunger in the center with a membrane that seals the orifice after filling the tank. The plunger then releases the water at level for supply to the wick pool. The membrane will eventually dry out and become ineffective. The only recourse is to buy a new cap. Good news that these are available.

Rated 5 out of 5 by from Excellent Bought two caps becuse my old unit is 11 years old and was leaking bad.That fixed the problem with the rubber seals but found out that my tanks were also leaking around the seams. I used some plastic model glue on all the seams and now all should be good for a few more winters.
