Stanley ACP0050-632 Classic Universal Stopper A

This stopper does have the pour thru ability simply by unscrewing one full turn. This picture does not show the sides of it, which have a channel that allows fluid to come out without taking the entire stopper off. If your seal is worn out it may leak and certainly not insulate as well as it should. Buying a stopper separately is not available at most stores anymore. I love my thermos and put coffee in it immediately to seal in the flavor and keep it hot for hours. If you leave coffee on the burner in your coffeemaker, not only do you waste electricity, you oxidize and burn coffee that makes it unsuitable for drinking. If you have a Stanley and have had a difficulty cleaning the inside of the thermos, I have an excellent suggestion on cleaning it. Add a quarter cup of baking soda, a little dish soap, and some copper BBs. You heard me right BB's. Boil water and carefully add it with the thermos in the sink (it will want to overflow quickly so be careful). Carefully add more water, but leave enough room in the thermos for empty space later when you shake it.. Let it sit at least an hour and put the stopper on. Start shaking and allowing the BB's to act like a rock polisher and scour the inside of the thermos til it is shiny like new. You may have to repeat this process if it has been several years since it was cleaned. A Tablespoon of BB should be enough to gently clean the inside of your thermos. You wont believe the nasty stuff that will come out when you pour out the stuff inside. Make sure you use a strainer with small holes to capture the BB's.You don't want them going down your drain! I rinse them off in the screen strainer and use them again for later. Hope this helps.Tasty coffee awaits your patience in using a clean thermos again. You won't regret it!

I was worried that after I lost my original stopper, I wouldn't be able to find a replacement. Alas, amazon.com saved the day again.While I must admit that some of these reviews weren't entirely promising, I decided to spend the six dollars after all (without the stopper, my thermos leaked constantly!).After receiving it in Stanley packaging, I rinsed off the stopper, screwed it on my thermos, turned the half-full thermos upside down (over a sink), and furiously shook the thermos for about ten seconds. Nothing spilled - the gasket is a perfect fit, the stopper screws directly into my thermos, and this replacement stopper makes it feel like I never lost my original one to begin with!

I was surprised that this not only included the screw-top but also the metal covering lid/top that sometimes people use as a cup, in silver with the same dark plastic green ring as is the color of the screw top. It fit my thermos perfectly. I didn’t need the extra metal covering lid/top but I’m sure at some point I’ll lose that too, so it’s very nice to have an extra.

I could not find the right size gasket at the time so I replaced the whole cap. I have since found the gaskets, so now I have a spare ready (not that I will probably ever need it!) Still, my classic green thermos is a life-long companion. Had to replace the cup last year because the old was was really dinged up bad from years of carrying into work.

It is "almost" identical to the OEM stopper it is replacing. The only reason it didn't get 5 stars is because the replacement part didn't fit quite as well as the old one. I did some research and this is, in fact, the OEM replacement for the stopper on my original thermos. My particular thermos is about 20-yo so there may be some manufacturing differences between then and now. Long-story-short, it does work, I just have to be careful not to over-tighten it because it will jump the threads and, if you're not paying attention, it will leak.As far as the vendor is concerned, they did great. Great price, quick shippment. I would recommend them and purchase from them again.

I was so happy to find this replacement stopper here at Amazon. My husband has had the tall Stanley thermos for many years, uses it daily at work, and it's still in great condition. But the rubber seal on the stopper had turned black over time, so gradual that I didn't even notice it or remember that it once was white. But recently it started leaving a black ring on the counter even after washing, and very soon after that the seal, which had not only turned black but hardened with age, broke. This new stopper is exactly the right fit and the seal is soft and pliable.

The item I received is different from shown in this picture, The ring is black rubber,not white sillicone. The top has a concave gap on the edge of the top of cap. The quality is not as good as the picture shown.

I purchased this to replace the original stopper on my 1.1 quart Stanley thermos (model # 10-01246-001) and the truth is that it works great, perhaps better than the original. I use the thermos just to keep coffee, and at times, even ten hours later the coffee is still piping hot . With the old stopper I would have to drink it all before five or six hours went by and even then it would only be warm. So if you're looking for an inexpensive stopper to replace the original stopper model # RS47, try this one, you won’t regret it. Again, it replaces the stopper for the Stanley 1.1 quart Overtime Vacuum Bottle.
