Frequently Asked Questions
Silicone Double Flange Pull Plugs are designed to mask holes and surrounding surfaces during powder coating and other high-temperature finishing processes. Their double flange design provides surface coverage on both sides of a component.
The two flanges help protect the areas immediately surrounding both sides of the hole while the central section masks the internal opening. This provides multiple masking functions from a single component.
The pull-through section is drawn through the hole until the plug is correctly positioned. This allows the flanges to sit against the component surfaces and helps speed up repetitive masking work.
Yes. High-temperature silicone makes these plugs suitable for compatible powder coating processes where the hole and surrounding surfaces need to remain free from coating.
The pull-through design makes positioning straightforward and provides an accessible section for removal after processing. This can improve efficiency when masking batches of components.
Yes. They can typically be reused over multiple masking cycles provided they remain undamaged and suitable for the application. Plugs should be checked for wear and excessive coating build-up before reuse.
