These stoppers work great to replace the threaded plastic caps that will no longer screw on my metal oil paint tubes! WidgetCo is my go to place when I need more of them. I previously ordered the wrong size (in my ignorance) and the authorized return with no hassle and immediately shipped out the new order.

High Quality EPDM Rubber
Searched far and wide for the correct sized stopper i needed. With free shipping, a wide selection and no minimum orders, WidgetCo came through. They definitely fill a niche in the market. It's one of the few places I could find these individually sized stoppers in small quantities.

Perfect fit for holes I drill in glass vases for use in semi-hydroponic water culture with orchids. Fill the base with water, let it sit define the orchid sucks up water, the pull the rubber stopper and let the excess water drain.

The graduated size made for a nice tight seal. Needed 7mm and the 5mm-10mm worked perfectly!

Stoppers came packaged very nicely. Some of the stoppers had a little flashing on them causing them to be slightly bigger than the 1/4" (.250) size that I needed. I will send them down to fit. Otherwise good quality.
Scott F., Wisconsin - 6/13/2020
Fast service, no minimums and free shipping - it really can't get better.

Rubber stopper plugs
I used these to plug a hole in a small bird feeder. When the feeder gets water in it, just remove the plug to drain. They have some give to them and each one is is tapered so that your measurement doesn't have to be so precise, just push them in as far as you need to. Fast shipment, well packaged.

Wonderful Rubber Stoppers
Great Rubber Stoppers. Replaced old cork with these and what a difference. Might get larger ones for wine bottles.
Carol S, California - 3/31/2019
It's nice to be able to get what you need when you need it. I have an unending supply of small bottles I use for my sand collection. These bottles have no tops or anyway low cost way to affix one. The Part Number: 7-R00000-EPDM-RS stoppers are perfect for the job and are readily available. Thanks for the good work.

These stoppers worked great for my application. Service was swift and accurate. Would use and recommend to others.
Larry L, Valley Center, CA - 5/29/2017
This one is perfect!
On my third try I finally got the perfect stopper/plug for the vintage tom turkey salt shaker I bought for future Thanksgivings that came without a plug. The matching turkey hen got a plug that fit on my very first try due to careful measurement. The first try for Mr. Tom was too big, the second too small. There wasn't an in between size so I had to get a little smarter. This plug is tapered so it fits several size holes. I hope this review will save someone else my trial and error method!

I have bought five different sizes and quality and service is outstanding. Once you figure out what size you need these people can fix you up. Their measurments are correct and texture is good for Parkerizing. Shipping is FAST.

Like many internet providers, WIDGETCO has items that local stores don't carry. These very small rubber stoppers are an example. Exactly the right size and material for my project and wicked fast shipping, all for less than the cost of fuel to drive into the big city!

I was extremely happy with the short delivery time, the great layout of their ordering website, and the quality of the stoppers I needed for ink cartridge filler holes for my large format printer. The dimensions of all the different WIDGETCO stopper sizes helped me a lot. I would certainly recommend WIDGETCO to anyone.

Shipment came in a hurry, and it was exactly what I ordered. Unfortunately, I ordered the wrong size (totally my fault). So I went ahead and put in a new order and I should see it I a few days. Thanks guys!
Travis S, Seattle, WA - 1/29/2015
Perfect for my French Horn Lead Pipe
My teacher and I needed a way to protect our horn cases from moisture leakage. These stoppers fit our lead pipes (where the mouthpiece attaches to the horn) perfectly. They seal the opening and seat half-way so there's no risk of the stopper getting pushed down the pipe. Excellent price - fast delivery - accurate dimensional description - would recommend these stoppers highly.
Mary K, Wayzata, MN - 1/27/2015
Appear to be Lab Quality
I've worked in many laboratories during my career. These, that I ordered, are for a home lab. However, they look, feel, and behave just like a good laboratory black rubber stopper should. The price was very fair, and delivery was fast. I would certainly recommend them to others.
Grant T., Salem, OR - 1/21/2015
