First Time Customer
I purchased 10 stoppers (#4 white silicon) The stoppers arrived and were exactly as described. They arrived quickly which was a breath of fresh air. No Covid excuses for lousy customer service. A little pricey but the product quality, customer service and no shipping cost made up for litterally a few pennies. Will order from them again.

Perfect for Justrite Gas Cans With a 1" Flexible Spout
These silicone rubber stoppers are great for plugging the flexible nozzle on my gas cans. Prevents dirt and debris from getting in while not in use.

Backup
I ordered the #1 for our design application and just in case we had to increase the hole size ordered the #4 also. The #1's fir our design perfectly and will use the #4 on our other project later on.

Drilling Holes in Silicone Rubber Stoppers
How easy it is to drill holes in the Silicone Rubber Stoppers? if yes what type of drill bit do you need?
RaulC, San Antonio, TX - 4/26/2017
Perfect fit 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.

Individual
The stoppers I purchased and received were advertised as being the correct size for plugging beer and wine bottles. Unfortunately for me they were not, as they are too large in diameter. I was forced to go out and buy a couple of inferior quality stoppers at the local Target at a cost of six dollars. I must now go through the trouble of returning the three one inch stoppers I purchased for a refund.
[From WIDGETCO: Sorry, but we could not find where this item was advertised as fitting a beer bottle. If you are aware of such an advertisement, please email us so we can research it further. Thank you for the feedback.]

Will order again
Product was as described and delivery was quick. Had no issues and will order from WIDGETCO again.
DAVID P., Dallas, TX - 8/13/2015
Perfect for my problem!
I used this product to plug the towel bar holes in a fiberglass tub unit, after the bar broke and I was not able to get ANY replacement parts. The stoppers fit the diameter perfectly. Looks like it was manufactured with these. My order arrived very quickly. Thanks.

F H, Albuquerque, NM - 8/16/2014
Great service!
I ordered #4 white silicone rubber stoppers; it was easy to place the order, delivered as promised, good quality, and reasonable price. This is my second time ordering from WIDGETCO and it will not be the last one.
Jose L, Englewood, CO - 7/17/2014
Excellent products
All of the stoppers I have ordered have been of the highest quality with fast delivery and good prices.
The silicone stoppers in particular work very nicely even at very cold temperatures.
Any chance of silicone stoppers being offered with holes?
[From WIDGETCO: Nothing planned as yet but we are always working to improve our product lines. This is a suggestion we will certainly consider. Thank you!]
