Standard Plugs Closed

These versatile plugs can be used to block off almost any easily accessible opening. They feature durable brass hardware, solid rubber, and a corrosion-free wingnut. Our heavy-duty plastic wingnuts are about the same strength as brass wingnuts (except in particularly dry environments), but are lighter and will not corrode over time.

We recommend choosing a plug size that is about 1/8” smaller than the inside diameter of the pipe opening you are plugging off. The measurement listed for each size is the actual diameter of the unexpanded rubber. Additionally, recommended pipe applications for each size can be seen under “Specifications” once you select a size from the drop down menu.
