The best powder coating plugs

Viadon stocks a full range of high temperature silicone, high heat masking plugs that are ideal for use during powder coating. Below is a short description of the different types we carry, and we offer FREE SAMPLES of most plugs & sizes (Contact Us for details). These will easily withstand temperature up to 600F, and are available in the following configurations:

  • Standard tapered plugs - simple, effective and most often ordered plugs.Powder coating silicone high heat plugs and caps
  • Tapered plugs with handle - much like the tapered plugs above but have handle on larger side for easier insertion/removal.
  • Hollow tapered plugs - as tapered plugs get significantly larger, so does their cost. Hollow sections on the narrower end of the largest tapered plug sizes reduces the total volume of silicone required to manufacture the plug, while retaining its external dimensions and masking properties.
  • Flangeless plugs - ribbed plug design with a narrow-taper plus a handle. Uses a harder durometer for greater strength, which aids in removal/insertion.
  • Tapered flange plugs - have a flange at the larger end to help create concentric masked areas for grounding or metal-to-metal bolt/washer contact.
  • Multi-flange plugs - a unique design that can mask multiple hole sizes, or provide good masking for holes with a large, chamfered area at the end.
  • Pull plugs - created specifically for masking threaded and non-threaded thru-holes in parts, typically for lengths 1” or less. Have a handle and plug section for quick insertion and removal.
  • Flanged pull plugs - same basic design as pull plugs above but has a flange at the end of the wider plug section. Perfect for masking lead/first threads or small chamfered areas and the hole length.
  • First thread plugs - first thread plugs are perfect for blind holes that are ½” in depth or longer. Masks the internal threads and the lead-in thread or small chamfer at opening.
