No, it's a metal to plastic machine flange fit, designed to be sealed with sealant. No gasket used by the factory. The reported sealant that Electrolux used is not even on ebay here, but it is from international sellers. Something 781 I think.
There's a video of one of the guys in this thread showing his 515 failure (that's not in this thread--in this thread is when he says hey, use this) BUT he's used 1184 since (as shown in that vid). This thread keeps kicking up when I search, so it needed updating for accurate reference sake.
I have Threebond 1184 in route. Dunn tinkin' 'bout it for a spell. The thing is that search results don't autmagically sort by date so old gets mixed with new. fin
