Caps, Plugs & Corks

Viadon's caps, plugs, and corks category includes silicone, EPDM and vinyl caps and plugs, and wood corks. They're often used for paint, powder coat, anodizing, and plating masking applications, but which have been used for other projects as well. Silicone is often chosen for higher heat applications up to 600°F and EPDM withstands up to 350°F.

STP Silicone Tapered Plugs Silicone

Viadon's silicone tapered plugs (sometimes called silicone corks or stoppers) are ideal for almost any masking situation involving threaded or non-threaded blind or through holes.

ETP EPDM Tapered Plugs

Viadon's EPDM tapered plugs are a great all-purpose solution to wet spray paint, plating and anodizing masking requirements of blind or through holes where carbon can be introduced to tanks safely. Made from flexible EPDM rubber, these plugs can withstand temperatures up to 350°F.

SC Silicone Straight Walled Caps

Viadon's silicone caps are ideal for powder coating, e-coating, plating, anodizing and wet painting. Inexpensive and reusable, they will withstand up to 600°F / 315°C.

EC EPDM Straight Walled Caps

EPDM rubber caps are often used for masking parts in lower temperature powder coating applications, plating tanks (that are not affected by carbon) or high temperature wet spray curing ovens.

SPP Silicone Pull Plugs Silicone

Viadon's Pull Plugs perform an important masking task - masking a through-hole in it's entirety with a single plug. How does it work, you ask? Place the narrow diameter end through the hole and pull the large diameter end through the hole.

EPP EPDM Pull Plugs EPDM

Viadon's Pull Plugs perform an important masking task - masking a through-hole in it's entirety with a single plug. Place the narrow diameter end through the hole and pull the large diameter end through the hole.

SFP Silicone Flangeless Plugs with Handle

Viadon's Silicone Flangeless Plugs are especially well suited for threaded holes. They are more effective than standard tapered plugs, because they also mask the top thread, without masking the surrounding area.

HTP Silicone Hollow Tapered Plugs

Viadon's silicone hollow tapered plugs are a great solution for many high temperature operations. The hollow core plug design allows for greater flexibility for easier insertion into threaded or non-threaded holes.

SFPP Silicone Flanged Pull Plugs 40-45D

Got a weld nut that needs the threads, and the top thread masked off? Silicone Flanged Pull Plugs are the solution.

TFP Silicone Tapered Flange Plugs

Viadon's tapered flange plugs are recommended for powder coating, e-coating, anodizing and plating. Providing a concentric mask around a hole, these silicone masking aids are ideal for establishing grounding surfaces.

SCE Silicone Expandable Caps

Viadon's silicone expandable caps (SCE's) take one standard masking device - the silicone cap - and make it better so that one cap can mask multiple sizes of threads, screws, bolts and studs.

VMFP Multi Flange Plugs Up to 600F

Multi-flange plugs are a great option when the priority is being able to mask as many different holes sizes with a small inventory of plugs. Allow for masking holes from 0.109" up to 0.709".

Wood Corks

Viadon's high quality corks are an inexpensive masking solution for most wet painting operations, and can also be used in hundreds of other applications.

Custom Molded Parts

Our in-house engineering staff can design parts from a drawing, sketch or the part to be masked. The products will be designed to your specifications and your material requirements.

VFC Silicone Flange Caps

Ideal for masking studs or bolts and a circular area around them, typically for grounding purposes. Alternatively, try using them as a plug - the area around a hole can then be masked by the flange.
