High-Temperature Protection for Powder Coating & Plating

Pull Plugs (SPP's) make quick work of thru-holes with a single plug to mask paint & other coatings. These masking plugs reduce your costs by allowing for faster threaded hole masking as these through-hole plugs are quick to insert/place.

  • High Temp Resistance: Withstands up to 600°F (315C°C), ideal for powder coating cure ovens.
  • Versatile fit: Designed to mask both threaded and non-threaded thru-holes.
  • Reusable: High-grade silicoen rubber will not hardern or metl, allowing for multiple uses.
  • Chemical Resistant: Safe for use in anodizing, e-coating and electroplating baths.

To see all pull plugs and other styles that work with common thread sizes, see our Masking Plugs & Threaded Holes Chart.

  • Masking 101 Helpful Hints

    When sizing for Silicone pull plugs, look for the major (larger) diameter of the plug to be approximately 2 - 4% larger than the hole when used for powder coating and wet spray, and 3 - 7% larger for applications where the part is immersed in fluid (plating, anodizing, e-coating) to ensure the best seal.

    • SPP's are ideal for use in powder coating, e-coating, plating and anodizing.
    • SPP's offer great high temperature and resistance.
    • HINT: If the plug is a bit on the large side for the hole, but no smaller stock size is available/suitable for the hole, try dipping the plug in water, alcohol, or some other liquid to lubricate it before pulling the plug into place.
    • HINT: Pull plugs can sometimes be, "backed in" to a hole - in other words, try pushing the plug "large end first" into shallow, blind holes, which may stay in place and mask more effectively than a tapered plug.
