When sizing for Silicone flanged 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.
- Ideal for use in powder coating, e-coating, plating, and anodizing.
- Use in temperatures up to 600°F / 315°C.
- 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.

NOTE: These plugs are manufactured from a softer (40-45 durometer, Shore A)
silicone rubber material than many of our other caps and plugs (55-60 durometer,
Shore A). This is to allow the flange to pass through a hole fully when removed from a part to be
masked. Due to this softer durometer, some plugs will experience a higher rate of tearing and/or
shrinking.
