Good replacement for the original
We’ve owned our Stanley thermos for 25 years or so. The original cap finally shattered after a drop. The replacement fits well and does not leak.

RS41. Almost as good as an OE stopper. But not quite.b
This is a direct replacement for the Stanley RS41 stopper used on the classic 16oz thermos. As well as many other Stanley products. It fits and is functional. Although it is a lesser quality build than the original. The Threads arent cast as well, so it tends to get crooked and can easily be tightened too tightly and become loose. The rubber seal was installed backwards on mine, but was easy enough to remove and reinstall correctly. The plastic itself is of similar quality, just poorly cast. I have used it for 7 days. And it keeps my coffee nearly as hot as the original stopper. But not quite as hot.On a budget... This will fit your old reliable stanley and keep your coffee hot for 8-10 hours. And gives you time to shop for an OE quality replacement.

Correct for Stopper RS41 - No Leak
A little loose but only a little more than the original. NO LEAK. Stanley does not sell or even have this stopper. They want you to buy a new bottle. “Made in China”. 60 dollars US for an 8 dollar part. Wasteful!

There is a good reason why Amazom posts a warning Indicating this item is frequently returned
For referance I have included a picture of my Stanley thermos bottle.This replacement stopper is slightly bigger than the original stopper.It will not fit insde the bottle, unless the gasket is removed.If I force the stopper in, the gasket falls offThis stopper has a better designed seat for the gasket. But the new gasket extends beyond the edge of the stopper and this Makes it to big To fit inside of the bottle. The original does not extend past the edge of the stopper.I will have to return this and continue my search for replacement stopper.

It fits. Kind of.
It fits my old Stanley 1.1 qt, but it’s nothing like the original. The pour with stopper partially on is really sloppy and I’ll probably just take it off to do that. It’s awkward to screw in, but once it’s tight it it’s technically functional. Probably not worth the price.
