#5 Rubber Stoppers with 2 holes

These are top quality EPDM Rubber stoppers. There may be cheaper stoppers out there but these are my first choice. Perfect fit and stopper softness. Another feature I love is that the stopper SIZE number is molded into most of them. My latest order did not have this feature. I hope WidgetCo corrects this. This is a real time-saver plus, knowing what size I have. WidgetCo carries many items that can be difficult to find. Great all round service. Highly recommended.

I am making a poor-man's medical suction for family use. (roughly the same vacuum strength as a dental suction) I needed a method of sealing a glass vessel as the trap for materials suctioned. I used a small glass bottle and sections of steel drinking straws for the input (material being suctioned) and output (vacuum) sides. The rubber stopper worked as conceived. The holes were the right size for the steel straw sections. Prompt service from WidgetCo. Stoppers exactly as I anticipated. Great pricing and free shipping.

Fast shipping, always in-stock, small orders accepted. In addition to their very high quality, this is why I use WidgetCo rubber products, exclusively.

The right size with 2 holes was impossible to find except here. Not only that, no minimum purchase and no shipping - Yea...

Let's face it...all rubber stoppers are pretty much the same...at least in my experience. But when you need just one or a few in a variety of sizes, it's great to have a vendor like WidgetCo who will sell you one or a couple at a fair price and with free shipping. Great company to deal with, prompt shipping, good quality products, no hassles.

I needed different size rubber stoppers from chemistry lab. I needed some with one hole, some with 2 holes, and multiple sizes. WidgetCo had everything I needed at very reasonable prices (cheaper than Amazon) and for me the shipping was free. They arrived very quickly. Thank you

Arrived promptly. Excellent quality and service. Thank you regards

Stoppers were received as they were described.
