Silicone Tapered Plugs, 600°F (powder coating, e-coating, anodizing, plating, painting, Cerakote and thermal spray applications)

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. Made from fully cured silicone to avoid leaching into plating tanks, tapered plugs are perfect for just about any metal finishing situation, including powder coating, e-coating, plating and anodizing. Ideal for use in Cerakote masking situations.

These plugs can withstand temperatures up to 600°F / 315°C and are clear so they contain no potentially harmful coloring agents.
