6.4mm x 4.8mm Stepped Silicone Plug | 16.8mm Length | Black

Engineered for high temperature masking work, this black stepped silicone plug is useful across powder coating lines, fabrication workshops and component finishing areas. Its 6.4mm to 4.8mm tapered section helps seal varied openings while leaving surrounding surfaces ready for coating.

The flexible body allows the plug to compress into suitable holes while maintaining contact around the opening. This helps create a cleaner masked edge and reduces finishing rework on parts where exposed holes must stay free from coating build-up.

What Are Silicone Step Plugs?

Silicone step plugs are reusable high temperature masking plugs with a stepped profile that helps cover several compatible hole sizes. They are commonly used during powder coating, anodising, electroplating, painting and spraying to keep holes, threads and internal surfaces free from coating or process contamination.

Common Applications

  • Masking general engineering components before high temperature curing
  • Protecting threaded and non-threaded holes on steel fabrications
  • Covering openings on machine guards, panels and powder coated brackets
  • Reducing coating clean-up around holes during repeated finishing runs
