Panel Plugs
Plug an electrical knockout or create a finished appearance with Essentra panel hole plugs. Our selection of products fits a range of panel thicknesses in hundreds of standard hole sizes.

Essentra sheet metal plugs are economical snap-in plugs that provide an attractive finish and secure fit for entry holes in sheet metal. These panel plugs are available in black LDPE in flush or recessed styles to fit hole sizes from 0.250" - 3.500".

If environment is a concern, Essentra PVC hole plugs are resistant to ozone, acids, and sunlight with excellent aging qualities. Our 26 different sizes are non-staining and available to fit panel holes from 0.187" - 2.031".

Essentra also offers durable panel hole plugs in ThermoPlastic Rubber. TPR is a hard material which has both the characteristics of rubber and plastic. Essentra TPR panel plugs withstand temperatures of 100°F to 300°F and are resistant to oils, acids, and alkalis. We also offer our blanking panel plug in TPR which is resistant to temperatures up to 350°F (short term). For a splash-proof seal our flexible plugs are made of Thermo Plastic Elastomer and are ideal for plugging holes in unused panels. The unique head design enables each panel plug size to cover a wide range of panel thicknesses.

For a clean and easy way to close optional wiring or access holes use Essentra locking plugs. We offer over 20 solid sizes and 3 vented sizes of locking plugs in black heat-stabilized nylon UL94 V-2 (CSA, Canadian Standards Association rated). Our solid style is designed to lock into multiple standard sheet metal thicknesses with a flush finish. The vented design allows heat and emissions to escape easily.

Achieve water tight protection with Essentra blind plugs and IP67 liquid tight plugs. Our blind plugs provide water tight protection to spare panel holes that need closed off in working temperatures from 40°F to 221°F. To close holes without a thread using our blind plugs Essentra offers optional locknuts in corresponding sizes. IP67 liquid tight plugs are made of black UL94 V-0 silicone and offer protection up to IP67 in temperatures from -40°F to 302°F.
