Plugs & InsertsVinyl Plus Plugs

More flexible than rigid poly plugs, Plus Plugs are easier to insert and remove with our unique 360° pull tab design. Plugs conform to internal threads and won't move during manufacturing and shipping.

Due to the flexibility of our vinyl one size often fits many holes. Choose the plug with a minimum OD that is slightly larger than the hole you are trying to plug.
