The perfect fit
After several attempts to seal my mother's antique handmade piggy bank, this stopper is the one that fits! Silicone is definitely the way to go with crafts that might not be quite perfect.

Quickly filled the order and was accurate.
JM, Connecticut - 5/23/2018
Product arrived on time and as advertised. I ended up buying the wrong size (too big) but was able to mold it to my needs. I don't need this sort of material often, but when I do, I'll be coming back here.
Jason M, Tennessee - 11/8/2017
This is an excellent product, very high quality, great selection of sizes, easy to deal with good fast service.
Ian O, Canada - 10/21/2017
I purchased these for a project I am working on and they were perfect! They're strong, all the same size and thickness and my order came faster than I had originally been quoted. Thumbs up WidgetCo!
Megan L, Idaho - 10/4/2017
These silicone stoppers are perfect. Silicone comes in many grades and densities so I wasn't sure what I was getting. Frankly, I did not have high expectations based on the pricing. However, I am extremely pleasantly surprised. Very high quality, dense and solid silicone with just enough flexibility to give a tight seal on the bottle and at the same time allowing for an easy release. You won't find better silicone bottle stoppers anywhere even if you pay several times the price of these. Also note the the company ships quickly, mine arrived in just a few days using just the standard delivery option. I'm always excited to find a company supplying an item that is for some reason hard to locate in the market and they do it by offering and excellent product, at a fair price, quickly and conveniently. You can't go wrong here.

Great Service, Wonderful company, Awesome!
Oh my goodness, size 7 white silicone rubber stoppers were the perfect fit for my old glass milk jars. I love to reuse my glass containers for juices and teas or just switching the milk bought in plastic jugs to my glass bottles. Such a difference in taste and temperature of the contents. I did order the size 9 as I was not sure which would fit the best, so i will need to return them unless my husband finds a use for them.

#7 white silicone rubber stoppers
#7 white rubber silicone stoppers arrived quickly and work perfectly for storing various foods and drinks in my old milk bottles.

Great company, great products
I have bad wrists and thumbs so I convert most bottle and container tops to stoppers. Never could have done it so easily without WIDGETCO.

Perfect for glass 5 gallon fermenter carboy
After making a 3/8" hole with a cork hole borer, I could fit my air lock and install the stopper in the top of my 5 gallon glass carboy fermenter. The grip was solid and the seal good right from the start, much nicer than what I have found with black rubber and other white (but not silicon) stoppers I bought with used equipment.

WIDGETCO Rubber Silicon Stopper
The site is very friendly and I ordered the stoppers to plug a bird feeder which had an unsatisfactory stopper. A reviewer had said how she had solved the problem with these stoppers and she was right. They fit perfectly and were shipped promptly which I appreciated and I think the birds did too. They are very well made and look like they will withstand the elements well.
Elise N., Cincinnati, OH - 6/9/2016
Exactly as ordered and early delivery!
Would definitely purchase more at this company. The stopper was for a vintage refrigerator pitcher and (luckily I measured correctly) the silicone stopper fit perfectly and is flexible enough to keep the liquids safe from spilling or refrigerator smells. YEAH! It was absolutely what I needed and perfect!
Mary Pauline K., Orange, CA - 5/27/2016
I ordered some of each size for liquid-tight bottle stoppers. Very happy with the quality, performance. Especially appreciate the high temperature range for sterilizing, as they are used for consumable liquids. Order was processed, shipped, and received in very timely manner (OK--Texas is close to California, but they processed the order very quickly). Order was received complete and correct. NO hassles!!
Dave S., Chartsworth, CA - 3/1/2016
Good quality finish and fit perfectly
Vaughan H, Canberra, Australia - 11/23/2015
Fit perfectly! Thank you!
Adrian G, Cocoa Beach, FL - 9/17/2015
Had been looking a long time for a replacement stopper for a bottle that was a gift which had a cork originally and it fell apart. I was happy to find your website. My order came
within two days and I now have a stopper which will last the life of the bottle. Thank you for your excellent customer service.
Ronald L W, Omaha, NE - 8/4/2015
I have ordered 2 times from this company and they always deliver on time. Exceptional customer service. The products are exceptional. Good quality product. Satisfied customer here.
Humberto A, Robins Air Force Base, GA - 3/24/2015
Simplicity done right
I used these in borosilicate jars, storing spices. The tapering fit makes them ideal for a variety of sizes and air tight seals.
Al, USA - 3/23/2015
Perfect for my needs
Using to Cerakote my guns. Perfect for plugging holes and avoiding unwanted overspray
Karl E., Asheboro, NC - 2/7/2015
Works great for my glass milk bottles.
Randy S, Denver, CO - 1/29/2015
An amazing resource
Who knew? I tried looking online for a stopper for a retro glass milk bottle I'm using and found this great source of perfect food-grade silicone stoppers that work perfectly. How did we live before the internet and access to amazing resources like this?
Kent S., City of Angels, CA - 12/27/2014
Best Online service I have ever had.
You hold the record for the fastest order processing and shipping that I have ever had. Thanks.

Retap bottle cap
Needed a food grade silicone replacement for my retap glass wate bottle. Works better than the cap it originally came with. Easy to keep clean and the perfect size as listed.

Milk Jug Cap
A better cap for the glass milk bottle.
C.F., New Hampshire - 9/23/2014
I have a lawn roller which is to be filled with water. I bought it without a plug for a discount. I tried a bathroom stopper which did not work. This stopper was perfect. The problem I have with WIDGETCO is they first sent these in a flat priority envelope. Needless to say the stoppers must have easily broke through the envelope. It arrived with only an invoice. When I spoke to the customer service they said they always send them that way with no problems. I insisted they send another in a padded envelope at least. The rep said he would try to see what he could do. It finally arrived in a padded envelope with the stoppers inside.
George Y, New Castle, Pa - 9/21/2014
I used these on my 5-gallon glass carboys, they are perfect! And, the shipping was very fast, thank you!
Rick L, Lincoln, NE - 5/21/2014
Excellent Service. Great Product
What more can I say. The quality is excellent and the shipping was very prompt. Would definately recommend to all.
T.L., Tucson, AZ - 2/8/2014
Fits my need. Fast delivery.
Fast delivery. When cut down to the proper depth they are just what I need for a new product. This was my second order and I'll be placing more.
Ken M, Redwood City, CA - 1/27/2014
Very nice product! Using it to stop hot liquid from flowing through a pipe. Food grade, rated at 350° F. Awesome!

Service was efficient and fast.
Ed M., Albany, NY - 7/1/2013
The best online experience I've ever had. You get what you order with quickness. I will go out of my way to send contractors to this site. A 10 out of 10.
JB W, Atlanta, GA - 6/4/2013
Great stoppers. I'd buy more.
Dave L, San Diego, CA - 5/13/2013
Exactly what I was looking for
This was exactly what I was looking for to close my glass milk bottles that I keep drinking water in. Cork stoppers got moldy so I bought other rubber stoppers but they infused the water with a strong rubber smell. Silicone is the solution! Shipment was very fast.
Karen M, NC - 3/27/2013
Silicone Rubber Stoppers
I ordered various cork & silicone stoppers because I did not know exactly what size I needed for a pottery jug that I have. These are just what I needed!! They arrived super fast and I would definitely recommend this company to others.
MJE, Columbus, OH - 2/15/2013
#7 White Silicone Rubber Stoppers
Good material compresses well to fit as desired and make a gentle but firm seal. Quick and easy shipment at a reasonable price.

#7 White Silicone Rubber Stoppers
Great service. Quick and easy!!!
JZ, Buckley - 9/30/2012
Using the stopper to plug ports in my BBQ where I put my temperature control fan. Pliable enough to stay put and obviously heat resistant.
