Stopper Gasket for SW-GCE36

Finally got around to replacing the old gasket on my lunch jar and this one fits perfectly into the lid groove. The seal feels nice and tight when I close it, and no leaks so far.

The rubber is stiffer than the original one that came with my jar, but it seated into the lid groove without any fuss. Took about two minutes to swap out and the lid seals just as tight as day one.

I noticed the gasket fits perfectly into my food jar's lid without any extra effort, and it seals tightly now like when I first bought the container. The old one was getting loose, but this replacement part restored the vacuum insulation completely.
