Nice plugs
Got these to to add a thermometer to a column. Used a piece of brass tubing to bore a hole in the center to insert the probe of the thermometer. The plug size was accurate and it works great.

Wondering if these would fit a Bottle or the Quality?
I already had a similar rubber cork like this for fermenting in plastic Five Gallon Carboy's (using the hole in the plastic top it came with) and fermenting overflow's in 750ml bottles but it seemed to always sink in too much so I measured the top and went with this #3 Silicone Stopper - and sure enough, it works SO MUCH BETTER!! It also stays in tighter so no need for worries - Cheers!

WIDGETCO has good stoppers
I was asked to review a recent purchase of a #3 White Silicone Rubber Stopper. Based upon my experience with stoppers, this was the best one I've procured to date. It was as described in the WIDGETCO specification and fit my application perfectly. While I have not confirmed precise material properties of the silicone, I can say based upon experience that the temperature range meets and may exceed the needs of most cooking processes e.g. 400 degrees F. I certainly will consider WIDGETCO for any future stopper needs.

Quickly received...always perfectly what I ordered!
I have purchased from this company numerous times...it's always for things I cannot find elsewhere and for pieces that lack what I am finding at WIDGETCO! Everything comes perfectly as ordered and super timely. I love this company!

Good stopper
Good stopper. Doesn't have the chemical smell that some other silicone products do.

Great stopper
The idea was exactly as described. I was 100% satisfied. Also, the shipping was incredibly fast. I not only recommend this company, I will shop here again.
Greg H, Tuscaloosa, AL - 10/9/2016
Very fast delivery
I was very satisifed with the quick delivery of this order. I bought the product to plug a drain in my swimming pool. I hope the silicone material these stoppers are made of are compatible with a salt water pool, but if not that is not the fault of WIDGETCO.

Perfect for my need
I bought a #3 and #4 size into which I wanted to install a 1/2" OD stainless steel dip tube for my beer brewing kettle, which has a welded outlet. I made a slightly smaller than 1/2" hole with a cork hole borer. The cut was clean and the dip tub fit perfectly in each. The two stoppers both fit into the hole in my kettle, just with differing depths of insertion. The seal is good and should work well to hold the dip tube rotated into the correct position.

Silicone to the rescue
I've been collecting spirits (Whiskeys, vodka, Rum etc.) for quite a while and never opened the bottles. Years after the purchase I find that the cork stoppers are falling apart. Well I never thought that I needed to tip the bottles like wine! I needed a food grade stopper to replace the originals. The silicone stoppers sold by WidgetCo are the perfect solution. They perform perfectly and keep the liquor ready for my next guest to sample.
Wayne S, Fort Myers, FL - 1/15/2014
These worked great
I needed replacement buttons for my longworth chuck. The originals didn't hold worth a hoot so I ordered these and the next size up, after drilling a hole thru them they worked way better than the originals. I'm very happy to have found these.
Dan S, Solon, IA - 1/8/2014
Just right
Exactly what I needed, when I needed it. Even the white color. Nice when everything goes right.
